Setting or Graphics problem?
I am trying to simulate a rotating object with GMO. It is a cube which rotates (or it should rotate) around a fixed axis outside the rigid body. Imagine it like rotating a big dice with a rope. M focus is only at a 10-12 degrees arc. So, when I input the data, and I have some first results this weird thing happens: I go to the display tab, and I can see the object moving for 1-2 frames, but then it starts deforming like being cut to slices with the same direction as the motion. Thes slices move together with different speeds as it seems. May I note that the fluid seems to be flowing on the surface, but it doesn't leave any marks, it's like passing through the object. I know, it is really weird, but if you have any clue, please help me. I will try to make the video out of the simulation when it is finished and I will update you.

Thanks a lot!!

Have you tried 2D slices, say in the plane of rotation?

Re: Setting or Graphics problem?
It seems to be a graphics problem, something is wrong with the rendering, because I tried several videos and they all were different. It struggles to handle the stl subcomponent. If there is any solution towards this direction...otherwise I will use my patience to render each image separately and then produce the video externally.

Well, if this is the hardware problem, then there is not much that can be done beyond replacing the card. So is it just slow or are the images bad?
