I'm still not very familiar with Geometry Nodes and can not figure out how to control individual hair length with them in the new Blender 3.3 Hair system. I've added a new hair object and added some straight hairs in the sculpt mode. Now I want to be able to randomize their length with Geometry Nodes without affecting their direction. I haven't found any node like "Scale Curves" or "Scale Splines", while Scale Elements and Scale Instances nodes don't work with Hair Curves. Transform node affects the whole object. I tried following approaches:
At first I tried to directly Set Position of the hair tips using Noise Texture with indices as X coordinates, but it just randomly moves hair tips all around. I understand the reason but it is not what I am looking for: I tried multiplying normals with noise which worked fine for the mesh displacement but I'm not even sure what the normals are for the hair curves. At least it doesn't work: I tried to capture Normals from the mesh object as a Named Attribute in all modes to use this attribute as vectors in the Hair Geometry Nodes, but it doesn't affect anything: I tried to fix Hair Normal rotation angle but failed: I am out of ideas of how to control length of individual hairs. Can anyone help with this please?
UDD. Uploaded .blend file with all 4 Geometry Nodes data blocks in it.
