I've posted this over on the FSDevelopers site, but it can take a while sometimes to get an answer and I need a quick response to this so I can go forward with what I'm working on. I am doing a winter ground texture which obviously requires a large amount of white. Running the compiler in SBX produces not white but red due to the "null value" setting of 255,255,255. I want to change that slightly to remove the red and get the results I want, but changing the inf file (photo01.inf is the only inf file I have found in SBX so I assume that's the one it's using to compile) has been futile because even if I change it to something like 254,254,254. . .when the compiler runs, it reverts right back to the original null, apparently it overwrites it. Anyone know a different way of changing the value so that it sticks?
