#Flicker off PAR

We have built numerous huts with thatched roofs within 3DSr4. Two of the four sides of the roof were square, but the other two were triangle. I created the triangles by moving the four upper vertices to the middle. When running the animation, the triangles flicker from dark to bright. I do not know why this is happening. Any help would be welcome. We are outputting directly to the PAR. Settings are medium, TGA.

Steve: I have had luck in getting rid of flickering faces by using CREATE/FACES/DETACH. Worth a shot. Bob

It flickers because, when you created the triangles by moving the four upper verts to the middle, you created coplanar faces. That's a big no-no when doing 3D animation.

Then how do I solve this problem. Can I rectify it easily, or do I need to construct new triangles; and how would I do that. I already went and deleted one of the faces by using Modify\face\delete, but I still have the problem. Any suggestions would be appreciated. Steve

Hi, Steve. PMJI, looks like you had 4 coplanar faces, and after deleting 1 you still have 3. Try deleting 2 more…this should solve your problem, if I am understanding your problem correctly…good idea to HOLD before each deletion.

Without seeing your specific file, I can't give you specific instructions. Perhaps one of the Autodesk guys can talk you through it.
