Super Beta V0.000.021 released, this is get suggestions only. Command & Conquer 5 Return of the Scrin (MOD Edition). I have been working on this since April 2013, only now I have a bit more than just idea's. Project on Hold due to Legal Blah Blah.
I have created map terrains for each faction.
These terrains can be used to plan Maps as you construct them, though can be left in the maps as basic Colours for obvious boundaries or to mark out objectives/points of interest.
The NRM is for the _nrm file that all these terrains use.
What's "NRM"?
As far as I understand it, it is the dictation of texture (3D effect), without it, the entire terrain looks too smooth. Look it up on Google if you want to know more, textures/3DSMax/W3X is not my strong suit.
Gen.Zool means NoRmalMap. I too thought it was a faction ;)
