No? Which companies go after texture mods?
I have no idea. Did you watch the interview? Sounds like people can get screwed over for the smallest amount of modifications. By the sounds of it it's not the textures that would be the problem, it's the working with a brand and IP that's not originally yours.
Some monumentally shortsighted companies go after fan games but I can't think of any that go after texture mods of existing games.
They bring up Project M, the Smash Bros mod, which got taken down by Nintendo, that's one example. Not a texture mod exactly, but a fan modification nonetheless.
I'm not the one that can answer these questions either. The whole thing I found interesting was here's an actual lawyer explaining something from their perspective. It was interesting and thought it applied here. It spooked me a bit as I love this project.
