Hello.
I have a simple question, I want to do a map mod for Rocket league and publish it as steamwork content.
But somehow for materials to work it require that file to be added along with the map to work.
So my question is, are we legaly allowed to distribute this file as it. (I use material instances from this file :slight_smile: )
PS: that is made with Unreal Engine 3.

I can’t speak for Psyonix on Rocket League modding rules or requirements, but Epic is ok with distribution of that file with a UDK project under the terms of the UDK license.
