When I make an animation in RDS 5.0 I am getting a constant shifting on the surface of the moving object (say a spaceship). It looks like the material or the material maps are changing and it looks like the model is passing under a tree with leaves that produce shading patterns that are shifting. I can not seem to find a solution to this problem and get a solid rock look on my model. Anybody know how this problem can be solved? Thanks.

It's strange ! Are you sure the map hasn't got any keyframe in your animation ? Fabien3D CREAFab, la crtion numique autrement...

I'm not totally sure if this is in Carrara, but do you have your texture mapped globally? I remember in Bryce that textures could be mapped in global or local coordinates, and that when an object moved in global coordinates, the texture map stayed behind, giving it a shifting appearance. I'm not sure if this can be done in Carrara but check it out just in case. This may be caused by procedural effects. Nebula Supernova Studios

Perhaps you have the atmosphere plug-in turned on in RD? I'd make an animation and use the Atmosphere and have the sky not animate, but it the ground texuture would still appear to undulate upon the camera moving when I rendered my animation.

It might also be a problem with the soft DRT shadows in RDS; you can see (sort of) here that the shadow edges tend to "dance" or look like leaves casting shadows. It only seems to happen with the soft DRT shadow settings when animating.

Thanks for the ryplies. I will try the suggestions and see if the problem is solved.

Actually, I came up with another idea - Are you compressing your animation at all? Quicktime compression introduces little artifacts that very closely resemble the dancing pixels in AzChip's animation. Turn off all compression, especially ANY Quicktime compression. If that doesn't solve it, then the problem is defienetly in RDS, not a compression by-product. Nebula Supernova Studios
