Hello!

I'm a beginner for Houdini FX 15.5. And I encounter problems while trying to texture leaves and trunks.

For my research requirements,I import a tree object(.obj) into the Geometry node,it is divided in to two part, one is for leaves and another is for trunks. The leaves object(.obj),including thousands of leaves, as a whole. I'm doing a tree morphing animation, so there are many different leaves and trunks for every frame,so I import obj as a sequence.


And HERE'S THE FIRST PROBLEM:
I find out that Houdini texture the leaves obj as a whole,not texture every single leaf,so I have to scale the texture in UVtexture node to a very small size so that I can see the map clearly. But the texture is quite weird.


From the attachments below, we can see that the texture is not mapping correctly according to the shape of the leaf.

HERE'S THE SECOND PROBLEM:

The texture of the trunks stretches in some directions.I don't know how to adjust the uv or choose which projection type to make it correct.

So I come here and share my problems.Is there any way to make Houdini recognize every single leaf as a primitive in the whole .obj so that I can texture correctly, and adjust the uvmap so that the texture of the trunks can be correct?

If anyone knows,please tell me and I would appreciate any of your help.
