Edit : I humbly deleted my long post as I've the answer

Stupid...(maybe no one noticed...unlikely :d)
I do have another inquiry though : I placed the wall in a dungeon and when I move around, I get clipping issues, as if the original base wall was still behind and both textures were overlapping...anyone knows where this could come from ? That's the script, if it can help

defineObject{
name = "TestWall01",
class = "WallText",
placement = "wall",
model = "mod_assets/models/env/TestWall01.fbx",
editorIcon = 28,
replacesWall = true,
}
Thanks !
