Rgbm as two maps not a png

is it possible to use two maps for lightmap png RGBM ? these pngs are always really big for me and not compressable. would it be possible to use two maps instead, one extra for the multiplier? so there should be a further multiplier map slot in the lighmap area…

thanks a lot for help

Hi @tomes,

No that’s not possible with the standard material. You will have to override the lightmap shader chunk, add a custom uniform for the second lightmap texture and blend between the two.
