Thanks for your response Philippe.
When I said "patches" I meant certain grass squares will recieve the mod, usually a few joined together, but no more than 20% map coverage.
I dowloaded all CMMOS Rulesets and CMMOS V3 first. I installed these to desktop. I opened CMMOS V3 first, then each of the CMMOS Rulesets. The 2 patches (Hi and Low Resolution) I unzipped directly into the bmp. Next I download and installed the mod packages. (except most Allied and Axies vehicles as I already had them) This was the second instalation, I couldn't get the grass mods to work in the first one either. Iniforms, shurbs, music all work fine.
When I view the CMMOS Log it says (low res.)txt" does not exist. With the second instalation I only installed two grass mods to see if I could get them to work first, before installing the rest.
After yesterday's post, I looked into the bmp file. I had allot of folders in there, I removed them. I re-installed all the CMMOS's again in the order previously mentioned. I downloaded and installed DD's grass mod for testing purposes, it didn't work.
Did I miss something? Thank You again for responding.
