Hi! The instructions are available on this project page!
Please let me know if you run into any issues
The settings there are for the built-in render pipeline. But generally for the leaves and branches you'd need to only enable 'alpha is transparency' in the texture settings, and also set the shader to render both sides.
The texture filtering of 'point (no filter)' is optional, but recommended!
The tree shader for URP might have a slightly different name, so it's a good idea to look for tutorials for URP specifically, if you're somewhat inexperienced.
At the worst case scenario, inspecting the settings of these trees might give you a good example for URP: https://assetstore.unity.com/packages/3d/environments/unity-terrain-urp-demo-sce...
For urp I did
- texture > alpha is transparency > filter point no filter (crisp psx)
- extract and map materials from mesh
- URP lit shader
- surface opaque
- render both sides (optional but some leaves are upside down)
- aplha clipping ON!
- using transparent mat promotes z fighting in render resulting in weird look > has to be opaque with alpha clipping
I'm in URP on Unity 6 and still get black borders and edges of the texture bleeding to the edge of the model.. I've tried URP Lit and Speedtree8 materials as suggested. Pretty stuck on how to fix!
Edit - of course after posting this I get something that works... URP Lit material and Alpha Clipping on, with the Threshold at 0.5, everything else as advised...
I had to reapply the material to the mesh in the Scene. And possibly I was trying to mass-edit Textures and maybe caught one that had a different setup, so changes didn't apply properly..?
