Black screen in 3D window

[Michal Forejt]

In AC 8.1, when I go to 3D window, I normally see model. But when I turn camera, whole window is black and I don't see anything. When I finish move with camera, I see model again. But it's too hard to find best view, when you don't see model during camera move :[


Thx and btw. excuse my poor english

Wow,
it's ok now. I made 3D window smaller and it works. I now, that 32 Megs is not enough and therefore I will buy ATI Radeon 9700 Pro MAC with 128 MB. I hope that will be fine:)

Thanks to everybody for helping me to solve this problem.

OpenGL seems to have a threshold - 64megulons is it. The 128 gives you this for two displays.... so don't overdo it.

Gudday,

I recently had this problem, and it was a real frustration, not being able to use the 3D OpenGL window! I use it all the time.

I tried the Internal Engine mode and it worked fine, but does not have the same effect for showing clients or for working with. When I did open in OpenGL, the window was black and would lock up AC in about 15 seconds. The file was OK if I just didn't open the 3D window using OpenGL.

I installed the latest video drivers off the net (ATI Radeon 9000 128MB) and it was working again.

ps.
I love how a 3D model in a program so hefty can whirl so smoothly with such brilliant effect (on myself and clients!).
And then the plans can be generated from that same model without needing redrawing in a separate CAD package.
All this was something that caught me up right back at the start!
