i have an model and i have unseamed it and texture mapped it with photoshop. i imported the map and everything looks awesome.
now i wanted to have a second map (png) that was transparent and had green line pattern on it. a separet material would then be self illuminent with the map.
but when i wanted to put the line map ontop of the texture map. it didnt work.
how can i have multiple materials apply to the whole object so that i have one map with the texture. and on top of that i have a line pattern map that is self illuminent.
i would appreciate any help about this. or work arounds so that the self illuminence only applies to one color in the map.
