Applies to the power of two, and can’t be larger than 1024×1024. But they can be 1024×512. Most importantly is the maximum dimension of 1024px, but both sides does not have to be equally sized. Save the file in RGB mode as a TarGA file (*.tga) with no compression and with Alpha Channels enabled in 32 bits/pixel resolution. file (*.tga) with no compression and with Alpha Channels enabled in 32 bits/pixel resolution.
A Diffuse Map is the result of all three RGB channels.
