Popular Post zeno Posted October 19, 2021 Popular Post Share Posted October 19, 2021 Hello everyone. I want to share with you some experiments conducted with ies files in the 2022 version, comparing renderworks and redshift with a texture bump and with 3 ies lights placed in front of a wall pointing 90 degrees towards the wall itself and the same three lights placed at the top, oriented downwards. I think the redshift rendering is much more realistic and beautiful to look at. On the left of each photo the renderworks version on the right is the redshift version. the image is 300 dpi 90cm x 50cm Z 6 Quote Link to comment
bjoerka Posted October 19, 2021 Share Posted October 19, 2021 (edited) i posted something similar to this issue i still wonder which renderengine is the more realistic one compared to the IES data... Edited October 19, 2021 by bjoerka Quote Link to comment
Vectorworks, Inc Employee Dave Donley Posted October 19, 2021 Vectorworks, Inc Employee Share Posted October 19, 2021 For IES you need to know that Redshift does not render "From User Input" brightness it only does "From Distribution". Set your lights to "From Distribution". You can attenuate the brightness inside a symbol with the brightness control in the Obj Info palette Shape pane, to make it go up or down.

rjtiedeman Posted October 23, 2021 Share Posted October 23, 2021 Are there any actual instructions as to how Redshift works in Vectorworks. I have been experimenting with old files that rendered correctly in Renderworks but the Redshift version is terrible. So I am missing info which would make this a successful experiment. 1 Quote Link to comment

HTH This sounds very helpful. Where are thes controls in Vectorworks Fundamentals? With out abbreviations please. What are IES files? I have only ever used standard spot, point and area lights from the VW light menu. I can’t find "From Distribution" in and menu. Sorry if this sound stupid but I am just looking for the key to the door. Edited October 24, 2021 by rjtiedeman Quote Link to comment

Sorry if this sound stupid but I am just looking for the key to the door. In order to get the ‘Use Distribution File’ option on the Light source OIP, you first have to change your Light mode to ‘Custom Light’. Then you can load the correct IES light distribution file for your luminaire. Refer to THIS thread for some additional information on IES lighting files. Also refer to the following page from the VW 2022 Help File: Light Source Properties 2 Quote Link to comment

Hello @rjtiedeman There are several Renderworks features that are non-functional with Redshift rendering. Grass, displacement, area and line lights, caustics. There is a known bug where glass can show as glowing, we have a bug logged with Maxon about that. If you can post a VWX file I can take a look. IES files are used with Custom light objects. I have learned to say IES more often because the light distributions are always IES files in practice. In the past when these light types were first added there were other options but the industry settled on IES files for this. Quote Link to comment

Thank you Mr Donley, So far I have found that I can’t just open old files make changes and render with Redshift. Renderworks works works fine so if I am ever to use Redshift I will have to figure out what to change so that I can move forward. I have been able to convert one file but I wasn’t very careful and didn’t make notes as to what I did to make it work. So I know it’s possible. However the comparison of the before and after are very close. I am not sure it’s an big deal for rendering displays. I ,have diverted my attention to relearning mapping which is challenging.

mjm Posted November 28, 2022 Share Posted November 28, 2022 I have to say that I find it a mood, when I can render caustics in several render modes except Redshift, not that Redshift can't do caustics, that feature just seems to be locked away from us, which stirs the same internal reaction like the BMW seat warmer nonsense. Closest I have come to get to where I want is to render the redshift, then render only the caustics lighting in an appropriate render mode (for me, preview spotlight gets me there), then composite them in PS. It's a bit fiddly, getting the right lighting intensities… Oy Quote Link to comment
