I can upload it for you along with few sample textures.
Anyway I don’t have problem with material not working or not know where are all those textures coming from.
I just like to know if there will be more samplers exposed in future.
Anycase I have found out that Unchecking Used with Static Lighting will make more samplers available. But I’m not entirely sure if unchecking it is an optimal thing to do.
Unless there is more clever way to pack as many as textures into single material as I want.
