How does the 3Dmax script load a bitmap as a gamma overlay?

[adamhahaEU2VH]

I can't find the corresponding property setting with showProperties.
For example this line of code：
tmp.texmap_bump = rt.VRayNormalMap(normal_map=rt.bitmaptexture(filename=d),normal_map_multiplier=1)
Is it possible to insert attribute modification in it to achieve the purpose of "set loading bitmap as gamma overlay"

Instead of assigning to the .filename property of the BitmapTexture map, assign new bitmap to the .bitmap one:

rt.bitmapTexture(bitmap = rt.openBitmap(texturePath, gamma = 1.0))
