Do you still get this issue in the latest version?

Ah, alright, I don't think I'll integrate substances to such a high degree at the moment. You can use its textures though :)

I'd prefer to keep bugs etc in here, if that's fine by you! Could you elaborate a bit on what you tried to do, what you expected to happen, and what actually happened?

Even if changed?

I don't limit the window size, this has to be a Unity limitation, sadly

Currently you can't use substance materials, but you can use substance generated textures. Was there anything in particular you wanted to be able to do?

Seems like particles have a very different way of calculating its position, the light positions seem to be in an entirely different space.
