  1. Hi All

    I am getting frustrated with Viewport Class Overrides.

    I have roofs and roof faces. They are all on class Roof-Main, which is set to 'use at creation'. All the roofs and roof faces have attributes set to 'use by class' (class style) etc.

    In my floor plan viewport I set the roof-main class to override so that only an outline of the roof will show. I do this by class override, so that Roof-Main has a dashed line and no fill.

    But only one of the roof faces accepts the class override correctly.

    The funny thing is, the override is partially working. If I change the color of the lines using calss overrides, then that works on all the roofs.

    The dashes only show on the one roof face, which also correctly displays the fill or hatch that I set in the class override.

    Anyone have any ideas?

    Thanks in advance. Mat

  2. Good to hear.

    I remember putting up with crashes for ages until finally I simply updated the video driver and voila. I tried updating quicktime, downdating quicktime, updating VW, updating windows, buying more RAM, and on and on. Seacrhing the tech boiard and trying all the suggestions.

    But simply updating the video driver fixed all my crashes.

    One of the techboard posts was from a VW Engineer which simply said "we have found most crashes can be traced back to outdated video card drivers."

    So there you have it.


  3. Hi All

    I am using the Renderworks Camera tool to set up my scenes. My project origin and my page are positioned bang in the center of the floor plan model.

    When I choose "display camera view", the 3d view (it's bounding box)is positioned way off center, meaning I have to pan and zoom to find it.

    Is there a way to trick the camera into positioning it's view on the page?

    Does this question make sense to y'all?

    Thanks in advance. Mat

  4. Hi All

    Has anyone got a quick and easy solution to get a white ceiling, with a soft pool of light showing from the light-source?

    I have tried using the matt reflectence shader, winding diffuse right down, and ambient right up. Of course, then I need to wind up the layer lighting level, which washes out the rest of the scene, but does give a nice white wall.

    If I dim the light source, then the shadows on the rest of the scene aren't as nice.

    If I move the light source away from the ceiling, then the overburnt area just occurs somewhere else.

    And I haven't got time for radiosity.

    I could build a lampshade.....then I get a huckery shadow from the edge of the shade. I could add another light, shining upward, with cast shadows turned off.

    But I really wanted something easier.

    Any ideas anyone, and thanks in advance. Mat

  5. Hi SRL

    In the Resource Browser, there is the option to edit the HDRI background. From here, choose Options, then wind down the quality. I find that for interiors, Low Quality produces a better result, since it cast 4 or 5 distinct shadows, more like what happens in reality with multiple light sources. Also, if you use high quality in interanl scenes, the result is often grainy. Apparently this is a shortcoming of HDRI, as it's not really designed for internal scenes. That's all I know.

    I have never had much luck with Radiosity - takes too long. But I haven't played with it much either.

    Good luck, Mat

  6. I used to do it like you (create symbol), but it becomes cumbersome when there are changes. I now just simply edit each individual window. If you get you classes right (style 1, style 2 etc) then the 3d appearance will on all of them at once.

    There's bound to be times when creating the symbol is faster, and leaving windows editable is faster.

    I figure if you have to open the file in 12 months time, remembering which windows are symbols and which aren't is probably too hard, and just overly complicates the job.

  7. It's on the layer DPI setting I think you want.

    Edit the layer to change it.

    We use 200DPI

    It's possible you have poor quality textures to start with, in which case you need to start with better jpgs.

  8. go to the sheet layer and select the viewport.

    In the OIP the bottom button is "Section Line Instances"

    Hit this button and use the drop down at the top of the box to choose "Sheet Layers"

    Put a tick in the viewport on the sheet layer you wish to see the section line.

    Be aware that naming your viewports makes this part easier.


  9. Hi All

    The new HDRI feature is great, and I have had some good success with it.

    The latest drawing I am doing however is exhibiting a pronounced grainness when the HDRI render quality is any higher than 'low'.

    Can anyone shed some light (haha) on this please.

    Thansk, Mat

  10. Hi All

    Here's what I do to improve my renders;

    1>Export the render as a jpeg, best quality

    2>Open it in photoshop, or the GIMP

    3>Duplicate the background layer.

    4>Use the find edges filter on the new layer, then set the opacity to 20-30 (Use 'difference of Gaussians in the GIMP)

    Sometimes it's worth experimenting and selecting all the white, and deleting it. This allows the edges to show through without bleaching your image too much.

    5>Duplicate the background layer again.

    6>Use the diffuse glow filter (soft-glow on GIMP), tweak the opacity until you are happy

    Import back into VW!

    Here's the pictures....

    The original image straight out of Renderworks


    the edge detect filter in The GIMP, I probably could have done more pronounced edges to get a more cartoony feel


    The soft glow filter in the GIMP


    With all layers on, and opacity adjusted


  11. Nicholas - diffuse glow in photoshop (on a new layer with opacity set to 25%), then find edges (of the original, (on a new layer with opacity set to 25%).

    Is, - you're right, I should have drawn the box - oh well it's gone to the Client now.

    Thanks guys


  12. Hi All

    I am designing an interior refurbishment for an elevator.

    I need to fake the drawing to give it a "expensive modern shiny look" rather than the crusty antique look that it has at the moment.

    I have played around with the light settings but the stainless steel walls either become too blue, or too yellow.

    The lights are an HDRI background, a little bit of blue layer ambient, a flourescent tube from the "accurate lamps" library, and a blue colored point light.

    Thanks in advance, Mat.
