Hi,
what I usually do is put the 3D member in an external cast. Then create another movie (e.g. call it "screenshot") the exact size you want the screengrab to be and place the 3D member on the stage. Put in a frame script to loop on the frame. When you want a screenshot, create (but don't open) a MIAW from your "screenshot" movie, and grab window("screenshot").image

I have run into this bizarre problem:
I have a 3D-szene, of which I would like to make a screenshot.
(win2K and winXP, Dir 8.5.1)
So here's what I do:
screenshot = new(#bitmap) screenshot.image = the stage.image.
I have tested this on approximately 10 windows machines from 400 Mhz to 2.8 GHz and it worked well on all systems as long as the 3D member was NOT directToStage.
However - as you can imagine - I don't want my 3D movie to run extremely slow all the times, so I decided to run it directToStage, but to switch DTS temporarily off just before taking the image of the stage and turn in on again afterwards.
Well this works fine on some machines, but not on all.
On some machines the screenshot doesn't show the 3D cast member, just as if switching off DTS at runtime had no effect.
I've been hunting for the reason why this is happening for some weeks now and what I have found out is:
It has nothing to do with the processor power of the machines. It could work on very slow machines and fail to work on fast machines. I figured out that it had something to do with the hardware renderer. If Director decides to use the software renderer, then switching off DTS at runtime fails to 100 %. If Director uses DirectX, it may or may not work. It works more often with DirectX5_2 than with DirectX7_0. If tested with OpenGL once and it didn't work either.
I have also tried to extend the time between switching to non-DTS and capturing the stage by some frames, but with no effect. With software renderer, it only works when the 3D member ist non-DTS right from the start of the movie.
Does anyone have a solution to the problem? Thanks for any help or comments!
