Texture showing in Custom Renderworks but not OpenGL

Recommended Posts

Can OGL use reflectivity or bump in Vectorworks? If you copy/edit the texture to Image color with no reflectivity or bump, OGL sees class colored seams on black background. RW renders get their grey background color from the image color controls in the bump and reflectivity shaders.

Guessing: If the image had some color other than black in the background, I think it would show in OGL as an image color texture with chosen or class color, which does not help if you need reflectivity and bump in the RW output.

Anyone else?

I think your right OpenGL doesnt show reflectivity, or bump and those are the shaders which are actually showing your seam so its just taking the object attribute colour. remember OpenGL is just your own machines graphics and isnt really using renderworks exept for things like shadows

Ah right, thanks.

Not a huge problem but it does mean I have to render in Renderworks to check the standing seam.

what you could do is have the colour shader use the bump shaders image but invert the colours then you can see it in OpenGL

OpenGL has been created to view a model in a qiuck rendered view, NOT to handle textures so it does not use rendering time, but gives you a colored 3d view of your model/drawing.

If you want bettering rendering and textures in Open GL, go to your Open GL options and select Textures, High or Very High Detail, anti-aliasing and so forth.

But then you've negated the purpose of Open GL!
