I followed many tutorials on how to create hair in blender with the new geometry nodes system.
At first when I create my first strands, their radius is way thiner than the ones everyone is supposed to.
And when I try to change the radius nothing happens.
I tried other nodes in order to see if the problem was coming from my node tree, but it seems not
I also tried the "Set Hair Curve Profile" node which neither has an effect.
It is the first time in my 2 years of learning blender that I got really blocked without finding an already existing solution.
Thanks a lot for your help, hope any of you could do something
EDIT_1 : I created this same node system on 3 different computers, they all have the same problem. Is there a prerequisite or a button I did not checked ? Don't hesitate to try the simple node tree on your own computer
EDIT_2 : I still can make a geo node group at the end to convert my hair to mesh and change the radius of my profile curve circle. But I loose all the interest of working with curves and my computer bercomes really laggy
