Displace Megascan Geo by uv in viewport Oct. 15, 2019, 5:59 a.m.

1. attrib promote: uvs from vertrx to points
2. subdivide the mesh
3. attrivop: bind uvs -> uv texture vop -> diplace along normal vop

comming out quite nicely. I like how the face coming down. Now I want to see the animation

Grain simulation troubles Sept. 21, 2019, 10:33 a.m.

Try to increase the constraints on the grain solver. The constraints works like how much layer can stacked one over another. So if you have 20 constraints, the solver can stack 20 particllayer. I am not sure if its 100% right…
But if you increase the resolution, you have much more „stacked layer“ to solve in stable way. so you have to increase the constraints much higher which cost a lot of simtime.

So my approach is to use low particle count as possible. Then I would upres the sim with point replicate SOP or you could use the vel field from the grainsim to drive some dumb particles(high count).
