Code: Select all

from pymaxwell import *
scene = Cmaxwell(mwcallback);
material = scene.createMaterial( 'mxm_test', False );
layer = material.addLayer();
bsdf = layer.addBSDF();
VAL = Cmap();
MAP = Cmap();
reflectance = bsdf.getReflectance();

VAL.type = MAP_TYPE_VALUE;
VAL.value = 100
layer.setWeight(VAL)

MAP.type = MAP_TYPE_BITMAP;
MAP.pFileName = "D:/DATA/weightMap.jpg";
layer.setWeight(MAP)
layer.setActiveWeight(MAP)

material.write('C:/Users/username/Desktop/mxm_test.mxm');

I am trying to assign both a weight value and a weight texture to the layer. I can drive both individually, but not both at the same time .. What am I missing ?

got it ! [this took a long time playing]

1] Cmap(); can have 3 inputs : a value, an rgb a bitmap
2] both value and bitmap have 'value' entries
3] thus --> to set the layer weight with value AND mask, one has to use the MAP_TYPE_BITMAP, then set BOTH the value and the pFileName of this 'Cmap()'

tricky ..
