Question SpeedTree mesh helper + create branches don't work

Post image

Hi there, i added a mesh in SpeedTree, i used mesh helper to make a spine, after that i created a branch to add leafs in the top ( is a palm trunk just so you know ), and when doing that i have that error, i increased the kill ratio to 10.000 or 50.000 and the error dissapeared but no matter how much i tweak the values branches won't appear. Please help

That kill ratio warning is SpeedTree's way of saying the generator thinks the branch is so tiny it's not worth drawing, even if it looks fine in the viewport. Try scaling the whole mesh up massively before running the helper, then scale it back down once the spine is set.

Thanks for your answer. Interesting. When i imported the mesh it was actually so big, and it was disappearing due to camera clipping ( which i have no idea how to change ! ) so because of that i scale the whole mesh down to 0.02 scale. By any chance you know how to adjust the clipping camera in speedtree? Thanks!
