These are quite good little low poly tree models, but there are some issues! I tried to import the FBX models into Twinmotion. They came in easy enough, but their pivot points are not at the base of the trunks, which is a bit frustrating. I then moved on the 3ds Max file, and in the same way the pivot point of the geometry was on at the base of the tree trunk. I had to edit every object to fix this, which is a bit frustrating. I would also like to make a suggestion for the materials too: the two colours, while clever to have them within the same texture, would be better to be two separate materials, both pointing to the same texture. This would allow a user to easily change materials on the separate parts without editing the texture.
The trees are also a strange scale, and I therefore had to rescale them.
I should also point out that while there are a large number of trees, there are quite a few of them that are strikingly similar, and therefore it feels like there aren’t really that many variations.
Having said all that, I do like them.
