Me and GKB have been thinking of doing a common tree atlas for our tree resources, and we would like to invite anyone else who made trees to join as well in this project.

We would like to include all tree mods if possible

The first issue is that we have lots of trees, and we will need a large tree atlas.
I have run some FPS [censored] in Tamriel and in Hoddminirs worldspaces using different resolutions for the atlas, 1024, 2048, 4096 and 8192. I can't see any FPS reduction with the higher resolutions, which surprised me.

If anyone would like to run some additional tests this would be much appreciated!

The idea is to test the load in game when using high resolution tree lod textures. I have included four variants of different resolution, 1024, 2048, 4096 and 8192.
The trees in each lod are colored with four different color (yellow, pink, blue and red) so it is easy to see that they are loaded correctly.

If you test this, please report your findings here.

I'm working on a dynamic Trees LODGen that will create atlases itself from provided billboard textures.

If everything will work as I planned, we can forget about those horrid atlases and compatibility hell
