Hi,
I have lastest version, and I tried to create groom, with optional mesh checked, and the groom is created.
But it don't appear in the list. I copied the lines between <mesh..>...<mesh> from one groom I created with older version and pasted it in the non working groom, and then now it is working...
hope it is clear, I don't have my computer in front of me.
Any idea ?
