  1. Hi Klinzey, I found a work around to it by just copying everything and pasting it onto a new file. The OIP fields then lined up. I checked my OIP Spotlight Preferences and indeed there were some customisations, probably over the course of 10 years of use. Before setting it to default, I wanted to keep whatever might have been customised so I saved a custom settings for lighting device parameter, and upon saving it the OIP fields lined up. I suspect somewhere along the lines these settings might not have refreshed when importing an older file, so all is good now, although this would definitely not be very intuitive to the average user. If there is any SP update for 2020 remaining perhaps this bug should be squashed. Great to know a solution for it though! Thanks! Gabriel
  2. Looking at the screenshots attached, we see that the data in the OIP does not make sense: DMX Address: 27.40kg I have already replaced the fixtures with lighting symbols from the 2020 library. The 2 screenshots are both of MAC TW1. One from the old file and 1 from the new library. Is there any quick solution to resolve this, or am I looking at manually replacing 200 over fixtures? Gabriel
  3. Cheers Kevin! I realised haven't given much thought to whether this would be a daytime scene or not. I suppose that means I will have to expand my experiment parameters and do both!
  4. Hi Kevin, Grant, Thanks for all the input. This is definitely still a work in progress. It was as much as I'd give my weekend to do all the tests so far. I'm likening these tests to a marathon that I will execute over a few weeks instead of a short sprint. Hoping this will be a LONG post eventually. Low settings are not the way to go, but it is a great way to understand what settings affect the which aspects of the render, without having to wait half an hour between each render. I have yet to experiment with the various directional lights - will do that in the next series of tests. I will probably compare what these directional lights do VS Ambient lighting. The ambient occlusion could definitely come down slightly. @Kevin K PMed you
  5. Test 8: Ambient On at 25% | Anti Aliasing High | Physical Sky Interior Renderworks Background | 01 x Line Light | 03 x Spot Light | Render time: 12m14s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting and Anti Aliasing👈, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: Physical Sky Interior Additional Light source in the scene 01 x Line Light at 5000 lumens with Cast Shadows and Soft Shadows checked 03 x Spot Light over kitchen counter at 4000 lumens with Cast Shadows and Soft Shadows checked. Distance Falloff set to Realistic Remarks: Where in Test 7, the contrast between shadows and light would be too harsh to be considered realistic, Anti Aliasing seems to smoothen that out into something acceptable for presentation. I suspect the round and curve elements for Spot Lights and the pendant lamp shades may have benefited from a higher Anti Alias setting. Render time take a big hit at 12m14s however, which is almost 3 times the render time for Test 7. Perhaps there is a need to weigh the options between render times and quality when there are round/spherical elements in the scene.
  6. It's the weekend! And I finally got down to doing some tests. Compiling results over here that hopefully might become a useful resource. What I've done is start from zero lighting sources, and progressively added them, taking note of the rendering times. Then with each permutation, one variable is altered so that I get to see the difference in quality and render times based on that variable. I place an emoji 👈 so that it's easier to pick out what the permutation is from the previous test. As a reference, I am using an iMac Retina 5K, 27 inch, 2017 workstation, 4.2Ghz Core i7, with 24MB DDR4 RAM and Radeon Pro 580 8 Gb Graphics. Test 1: No Ambient | No Environment Lighting | Render time: 2m28s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: Off Environment Lighting: None Remarks: Scene is full dark with zero sources of lighting. Interesting that reflective surfaces do render reflection even without light sources present. Also note the image prop of a hanging plant is self illuminating, perhaps suggesting it does not interact with lighting? ----- Test 2: No Ambient | Physical Sky Interior Renderworks Background | Render time: 3m06s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: Off Environment Lighting: Physical Sky Interior👈 Remarks: Adding Environment Lighting immediately adds a lot of information to the scene. The slight glow at the end of the room adds some depth to the scene and suggests that's where most of the light is filtering in from. Indirect Lighting Texture Options under Glass RT set to enable portal. Minimal impact to render times. ----- Test 3: Ambient On at 25% | No Environment Lighting | Render time: 2m33s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On 👈 Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: None👈 Remarks: Comparing this with Test 1, the only change will be turning on Ambient lighting at 25%. Compared with Test 1, again a lot more information in the scene, but noticeable a lack of depth when compared to Test 2. Notice the False ceiling on the right blending directly into the main ceiling itself. Additional rendering time (5 secs) is actually negligible when compared to Test 1, and it is in fact faster than Test 2. May consider this as a more detailed render with all light sources as opposed to OpenGL (which has a limit of 8 lights). ----- Test 4: Ambient On at 25% | Physical Sky Interior Renderworks Background | Render time: 3m11s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On 👈 Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: Physical Sky Interior👈 Remarks: Now we start combining two lighting sources, Ambient and Environment lighting, and the scene again looks better than Test 2 or 3 where only one light source was defined, as we get more information and depth as well. Render time is excellent at 3m11s. ----- Test 5: Ambient On at 25% | Physical Sky Interior Renderworks Background | 01 x Line Light | Render time: 4m19s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: Physical Sky Interior Additional Light source in the scene 01 x Line Light at 5000 lumens with Cast Shadows and Soft Shadows checked👈 Remarks: Adding a third light source into the scene, we get more depth information of the false ceiling with respect to the main ceiling. Overall the scene looks slightly better lit than Test 4. Additional render time of 1min for 1 light source suggests that the light sources do start making renders more complicated. There is some splotchiness where the line light grazes the ceiling. ----- Test 6: Ambient On at 25% | Physical Sky Interior Renderworks Background | 01 x Line Light | 03 x Spot Light | Render time: 4m28s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: Physical Sky Interior Additional Light source in the scene 01 x Line Light at 5000 lumens with Cast Shadows and Soft Shadows checked 03 x Spot Light over kitchen counter at 4000 lumens with Cast Shadows and Soft Shadows checked 👈 Remarks: Adding three additional spot lights into the scene, the scene looks better lit than Test 5, with the pendant lights defining a nicely lit space around the kitchen counter. Interestingly, the additional render time of 9s for these 3 spot lights suggests that not that much computational resources are required as compared to a Line Light source. This 9s also is for computing the additional geometry of the lamp shades, so really not much load added on to the renderer. Notice also that the hemispherical shape of the lamp shades have a jagged edge to it, which likely suggests a higher Anti-Aliasing Quality is required (currently set to low). Also note the underside of the lamp shade is dull, and is missing a quality of a glow usually present. There is some scalloping of the lights on the wall on the right where the 2 bar stools are, and the contrast between light and shadows seem a bit too harsh. ----- Test 7: Ambient On at 25% | Physical Sky Interior Renderworks Background | 01 x Line Light | 03 x Spot Light | Render time: 4m31s Options Anti-Aliasing, Shadows, Textures and Colours checked. Additional options under textures were all left unselected. Quality All Low except Indirect Lighting, set to High. Max Reflections: 3 Lighting Options Indirect Lighting: Interior 16 bounces Ambient Info: On Brightness: 25% Ambient Occlusion strength 50% / Size 100 Environment Lighting: Physical Sky Interior Additional Light source in the scene 01 x Line Light at 5000 lumens with Cast Shadows and Soft Shadows checked 03 x Spot Light over kitchen counter at 4000 lumens with Cast Shadows and Soft Shadows checked. Distance Falloff set to Realistic 👈 (previously set to None) Remarks: Compared to Test 6, we now see a nice glow on the underside of the pendant lamp shade. The scalloping of lights on the wall on the right is still present. It is an improvement from the previous test, where the contrast between light and shadows are now a little more subdued, although I would still consider it unrealistic. Starting to notice some leakage of lights from the Line Light source which does not look ideal.
  7. Hi Dave, Currently there is only a Heliodon which I have set for Singapore, 6pm +8hrs GMT, where I am currently based. I did not know there was a "Use Portal" option under textures. You do learn something new everyday with VWX, even after using it for 10 years! Will definitely give that a go.
  8. Thanks Kevin! That's a fabulous suggestion which I can see for sort of the finer controls . Will try that out over the weekend. Hoping to post some improved renderings.
  9. Hi Mark, Thanks for the tips. On to experimenting! Cheers, Gabriel
  10. Hi all, Taking a deeper dive into this rabbit hole of Renderworks. Trying to figure out what causes the patchiness on Custom RW. Looking at the Custom RW render along the orange selection of the ceiling object, on top of the ambient occlusion effects, there are patches of white that make the whole ceiling look like mould is growing. I have included the Custom RW settings and lighting options as well. Nothing out of the ordinary here. The Walls and Ceiling objects are basically using a White Paint RT, using Color for Color Shader and Plastic for Reflectivity Shader. And just for reference, I have attached a Final Quality RW, that undesired effect is still there, though not as pronounced. What gives? Gabriel Vectorworks 2020 Spotlight
  11. Hi Mark, Incidentally, I attended your webinar just yesterday. Thoroughly enjoyed it. I was the one asking the question on whether to place the NURBs curve for better snapping on the same class as the truss geometry or not. Will definitely be looking out for that video when it is made available. Anyway, I'm looking at the modified file, and it seems that you've shifted the 3D loci to all coincide on the same x-axis, and the geometry seems to line up pretty well. The only issue is that the beams now originate from this new 3D loci position. Which I suppose is alright if I am not rendering the look for a client. I was planning to give up on the lights focusing to a proper focus point and just have it "pre-focused" in my symbol orientation. After a bit of fiddling, I did find a workaround by replacing the nested 3D symbol of the clamps with just the 3D geometry of the clamps affixed to the geometry of the yoke. This helps to retain the beam originating from the centre of each cell. Thanks for the help! Gabriel
  12. Trying to create a multi-circuit symbol. Working on Vectorworks 2020. I have created lighting symbols for the individual cells. They all have a z height of 0. I then add 2 3D loci also with a height of zero at where the clamps would have attached onto the pipe. So with the 6 objects selected, i.e. 4 individual cells + 2 3D loci, I proceed to create symbol. Thereafter, adding a light info record to this newly created symbol, I manage to insert the multi circuit symbol. However, examining the positions of the clamps, it seems they are not in the right position. Is there a solution to rectify this, or is this a bug? Gabriel Multi Circuit fixture.vwx
  13. Looking at the resource manager, there's a FixtureID field that is not accessible in Spotlight Lighting Symbol Maintenance. Does anyone know what this is used for and how it can be editable? I'm in the process of converting my old files created in VWX2017 to 2020, and this thing came up. Gabriel
  14. Just hopped onto 2020 from 2017, and I have this same question myself!
