I’d importered a model from FBX with one of a alpha texture(*.png) just now.Then I loaded the model,setting the material(with the alpha texture).I sadly found that the material didn’t work probably while it worked normally in Material Edit.The error code is ‘Failed to create input layout for shader LitSolid(DIRLIGHT NORMALMAP PERPIXEL) due to missing vertex element’.What was the matter?How can I deal with it?
