hi all 
it’s been some day since i posted !
and here am i back with some new thingies.
blender handles atlases, but unfortunately dont handles texture arrays.
I had to find some tricks and i’d say shader almost works fine for splatting textures
Tho it’s not yet finished, here’s a pic of the very first model i posted here that i reworked and rendered quickly:
I now have to do the same thing for ground textures and then… rework all my models so that they look better.
Anyway i hope you like it
happy blending !
EDIT: if some want the splatting material nodes, just ask here and i’ll post it
