and  do you know an easy way to fix this directly in the code ? (I am not a shader coder myself, but if you have a clue, I can ask around me :-))

Hey there, 
I was wondering is there was any imrpovement on this case ?

Thx :-)

Hey, I just wanted to know if there is some updates on this issue ?
I just tried to use one substance mat with a shader forge made shader and I just noticed that I can't (same issue than above)

I can do my texture manually but it's kind of a pain for the artists, as I put different kinds of informations in different channels.

Thx a lot :-)
