hello i'm trying to make a tree sim but i cant make it ben and be stiff as a tree.. i set the parameters to be as much as stiff as possible but nothing

I'd guess not enough substeps and/or constraint iterations. What are your Settings in the Solver?

You might need to use the vellum constraint to "glue" branches together (I think...)

For the tree falling down, I've had the same problem and substeps helps but the main problem I had was, when I start the sim, the tree moves/bends a lot. I'd want the starting pose to be stable. I never understood how....

Hey,

I thought I'll give this a quick try. I am aware that the geo is a bit trashy, but I wanted to test it anyway.





It is the vellum hair constraint, glue constraint, four substeps and 4000 constraint iterations (this might be way to much). Of course this would need some tweaking, but I think it works in general and I hope it helps.
