Are you not suppose to see the leaves underneath, and are the trees suppose to have a bunch of black spots? I’m using Unity, trying to use this for my terrain.
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...
