Vellum Grains Issue - restless grains

[elPato]

Hello friends,

I have a issue with vellum grains. The simulation itself works well, but not with geo.

The substeps are on 15.

I copied the geo with copy to points. When I use spheres as geo, I dont have any problems, but with other geo the grains are still restless. You see it in the attached video.

Can anybody help me please?

This is because of the orientation of your points (in this case, your normal attribute N). One way is to override the N attribute after the simulation with a point wrangler with this : 

v@N = (0,1,0);

But you'll not get any rotation on your copied geo. If you want rotation, you should use rbd and a very low proxy of the copied geo as source. Also, 15 substeps is way too much. Try increasing constraint iteration to something like 1000 before increasing substeps.
