Question about alpha clips

[rrobnett]

has any one know how to set up the material and texture files for an alpha clip or opacity mask setup. I think I did what the manual indicated but I get an error :
No shader uses this combination of textures [IncorrectTextureMask]
"No shader uses this combination of textures : {'Textures': [<FbxProcessor.FBXTextureHelper object at 0x7fb6512c22d0>, <FbxProcessor.FBXTextureHelper object at 0x7fb65033abd0>, <FbxProcessor.FBXTextureHelper object at 0x7fb65033a810>]}"
I have tried a few other things but get the same error when uploading.

_OP

I'm far from an expert and I'm not sure about the specific errors but maybe this helps:

In your 3D software give the material a name ending in _OP like "Material01_OP"
Then name your textures "Material01_OP_BC" "Material01_OP_OP" "Material01_OP_RN" etc.
In the mask the parts that should show have to be white for 100% opacity, the invisible parts black for 0% opacity.
