Hi allI have found that my system prefers to have external a/c textures in DXT3 format(with no mipmaps) and I have been converting any of my a/c 32 bit or DXT(with mipmaps) textures using the DXTBMP programme. Generally these external textures have a T in their file name. However sometimes, the BMPs associated with the VCs are also large file sizes and I suspect that they also are 32 bit files.So can somebody who is in the habit of converting their texture files to DXT3 tell me which files should be converted?Thanks in advance Barry

I change all textures when I insert new liveries / aircraft. I change all daytime textures (usually the ones with the T you mentioned) to DXT1 with Alpha & all nighttime textures (usually with an L) to DXT3. I find DXT1 loads better that DXT3 & I have yet to see any real degradation in quality. The only reason I keep the night ones in DXT3 is that the lights don't show in DXT1. As for the VC BMP's, you have to be very careful. I have found that many don't show at night if you convert them to either DXT1 or DXT3. I don't really know why. Best is to make copies & experiment.Hope this helps
