viewport rendring in OpenGL

[joerg]

having 2 layers created a viewport and set the top layer in the viewport layervisibilties to grey ind rendered beautyfully transparent.

But in 2010 it doesn't!! am i missing something? or is this a bug? This was ( or hopefully is a very nice feature!)

Check your Preference and make sure you have Quartz Imaging turned on. I think this is required for transparency effects.

Thanks Pat, i had Quarzimaging turned on ...!

Your right. It seems to be broken in VW2010.

If you use a Unified View and render in OpenGL, the grey layers are translucent.

If you do the same thing in a viewport, they are opaque.

Can you use Fast Renderworks instead? Slower, but at least it does the transparency.

Funny, but OpenGL does work in Design Layer Viewports. But when you make a Sheet Layer Viewport of the layer with the Design Layer Viewport it does not work.

Thanks again.

i might report it as a bug than! Hey i paid for an upgrade not a downgrade ;-) There are probably workarrounds but i liked the siplicity of it! And i like the look and speed of openGL. It has a bit of the Sketchup look, still a drawing not too realistic!!!

cheers Joerg
