i have some problems with the assimp model loader and my textures and transparency. I am exporting my models from Blender to *.x files. Which works much better then the collada export from blender. I am now stuck with a problem when i use textures with alpha transparency.
There seems to be a problem with correct normal interpretation or something different. For a better understanding see a screenshot below:
The area which schould be transparent cuts away the leave behind it in the size of the actual mesh.
Now I like to know if somebody here has similar Problems and maybe a way to solve this. I am not sure where the actual problem is. Blender export is kinda crappy sometimes.
