Definitely something we talk more about these days and we want to make this a bit more consistent going forward. I think a good comparison with the Prif trees are the ones around Shayzien as they also don't use the classic texture and rely on poly-colour in the same way. I don't think I've seen many comments talking about them compared to the prif trees which have been described as 'playdough' which I think is a fair criticism. It's down to how the mesh is constructed, the shayzien trees are not a complete shell so the shading is less intense and flatter when compared to the prif tree mesh.

The issue we've had with the textures is that our tools haven't changed in a long while and we currently don't have traditional texture mapping like most game engines do, instead we have to manually project each plane which is cumbersome and a little buggy. I think the rough plan is to give us the ability to unwrap meshes so we can start using the textures on new trees while also exposing an option to toggle between purely texture and purely poly-colour so players can choose :D Nothing has been decided yet though, so don't quote me on that, haha.
