[nemo77]

hi guys

i m new to modding and i recently discover polished landscapes mod by Gutefiek.

after adding it, i realize that desert trees wasn't implemented in map
I ve export from native (static mesh) map_desert_tree and import in a BRF of my mod.

The mesh looks nice on OpenBRF but in game show an ugly mesh.

i ve paid attention to shader, flags, materials...
and it doesn't work this little bull**** drive me insane for 3 weeks now

any suggestions are welcome

thx
