line-weight Posted December 4, 2017 Share Posted December 4, 2017 (edited) For editing and for early-stage models, when working in OpenGL perspective views, I like to turn textures off (under "OpenGL Options"), because I find them distracting when working on the basic geometry. However, this makes any material that should be transparent, like glass in windows, appear solid, which is not what I want most of the time. Also, it means I can't really use this mode for creating quick presentation images and so on. One workaround is to give the objects that I want to appear transparent "no fill". That works in the basic OpenGL view but it then means that textures aren't applied if I switch them on or do a rendering. I control materials by class. When I edit a class, in the "Graphic Attributes" dialogue, under the "fill" options I can adjust opacity. This ought to so what I want, but it doesn't seem to have any effect in OpenGL view. Am I missing something? Edited December 4, 2017 by line-weight Quote Link to comment
Vectorworks, Inc Employee PVA - Admin Posted December 4, 2017 Vectorworks, Inc Employee Share Posted December 4, 2017 Correct, there are a number of wishes in related to this at the moment. Often I just disable Color from OpenGL instead of texture to get clear windows and still have gray geometry, but that mainly works because I only give objects 3D attributes via textures and not via solid fill attributes.

Phil hunt Posted December 4, 2017 Share Posted December 4, 2017 really need a white model render.....but in open gl which would be great.......guess as jim said build your model without colours and then apply the textures when your happy with the geometry at the end Quote Link to comment
zoomer Posted December 4, 2017 Share Posted December 4, 2017 I think that would be a very nice idea. For now, doesn't it work by Class transparency ? And I would like to get my OpenGL transparency back - when using C4D imported Materials. Quote Link to comment

It only affects 2d screen plane or 2d layer plane objects. Once you turn something into 3d (extrude or convert to NURBS for example) it doesn't do anything. Kevin Quote Link to comment

Often I just disable Color from OpenGL instead of texture to get clear windows and still have gray geometry, Have just tried this and I see that disabling colour: - does remove colour - does remove the image maps associated with the textures (whereas you might expect that it would make them greyscale) - doesn't remove the transparency associated with the textures As ever with VW not exactly intuitive but useful to know. The reason I like to have the colours on is that I find it makes models more legible whilst working on them - provides distinction between materials (or whatever you use your classes to control) without the distraction of the tiled image maps, which can make edges hard to see.

Phil hunt Posted December 6, 2017 Share Posted December 6, 2017 i sometimes use no colour but add line edges in open gl ....that works for me to Quote Link to comment
