problem with multimaterial

[ZeBoxx2]

two problems...

one, scope; monoOutput is a property of the bitmaptexture, not of the material. You're currently trying to set it on the material

-- current code
multiMat[3] = standard twosided:on diffuseMap:(Bitmaptexture fileName:(p3)) opacityMap:(Bitmaptexture fileName:(p3)) monoOutput:on

-- current code collapsed for clarity:
multiMat[3] = standard twosided:on diffyseMap:someMap opacityMap:someMap monOutput:on

-- code you want, presumably, but see below:
multiMat[3] = standard twosided:on diffuseMap:(Bitmaptexture fileName:(p3)) opacityMap:(Bitmaptexture fileName:(p3) monoOutput:on)


two, value type; monoOutput expects an integer - which is any whole number like 0, 1, 2, 3, -1, -2, -3, etc. In most cases in MaxScript, that integer represents an underlying value. In the case of monoOutput:

.monoOutput -- Mono Channel Output:
-- 0 == RGB Intensity
-- 1 == Alpha


Presumably, you'd want to switch the Mono Channel Output of the opacity map to use the input map's alpha channel. So instead of 'on' (which is a boolean value.. like true/false), you would use '1'.


multiMat[3] = standard twosided:on diffuseMap:(Bitmaptexture fileName:(p3)) opacityMap:(Bitmaptexture fileName:(p3) monoOutput:1)


I hope that makes sense :)

Thank you!
I was struggling with this for a while
