Simplex started as a branch from Complex. It has combined features from Path To Victory as well as many other mods through a long history of R&D. This mod aims to excavate the full potential of the Homeworld 2 engine and it will simply blow your mind with incredible fun!
You should make sure to credit Siber and EatThePath for this. I know from reading the pdf file for HWAT you're allowed to use their models, but you must credit them first.
Sure I will credit them. And I'm waiting for reply from the Homeworld @ team.
If you're waiting for a reply from them, then you shouldn't have posted this in the assumption of their response. They may have said in their readme that folks can use their models, but it still isn't polite. Then again, I'm a stickler for these kind of things.
