I'm sure this is an old topic but can't find anything in search.
In 8.1, WIN, textures don't remain assigned to materials, flipping back to the original in library objects. I can't see that it is the objects. These are varied, from the 8.1 library (newest), 3rd party etc.
This is very annoying! I can sometimes get a render going before the flip but often I can go around in circles changing the texture (so many clicks!) to have it flip in the 3D window. The textures are usually from the AC library but others do the same thing. Objects without textures also flip colours back to the "factory" setting (eg. off-check the "use objects materials doesn't always stay set but the box remains unchecked. Turning it on then off resets OK but it may not stay)
Yesterday, I could not get a glass to be transparent. I had to set the OpenGL options transparency slider to below 60% to get the 3D window to show transparency but this may/may not stay put for the render.
Anyone seen this behavior before?
