Hello from Brazil! =)
I don't speak english very well, sorry for any error, but I think you
can understand me!
I'm trying to load a model into Away 3D, that's ok, the model is
loaded perfectly, but when i try to apply a simple texture, like
colorshading, or even wirecolor I can't, the model stay black, I tried
with all types: obj, dae, 3ds and in all cases i get the same result.
Model in black.
Can you help me, please?
Thank you very much!
