Transparent color channel
I am a new user of MaxScript.
1- I need to apply an image with a transparent color # 185 With rgb 255 0 255
the image is used also in POV_Ray
...
texture
{
pigment
{
image_map
{
gif ImageFile
once
transmit 185, 1.0 // rgb 255 0 255
}
}
}
...
2- with this I am able to display the image but with the transparent color
...
theBmp = openBitMap "Image.gif"
meditMaterials[23] = RaytraceMaterial ()
meditMaterials[23].diffusemap = bitmapTexture()
meditMaterials[23].diffusemap.bitmap = theBmp
meditMaterials[23].showInViewport = true
...
cylinder ...
material:meditMaterials[23]
3- I need help.

Then dont store alpha
Then dont store alpha channel in your bitmaps.
See attached shot below.
my recent MAXScripts RSS (archive here)
I changed all from
I changed all from "diffuseMap" to "opacityMap" on above script.
The image is displayed with transparency OK, but with "gray scale" color.
I am a beginner, please continue to help me.
Thanks.

This was asked many times
This was asked many times from the first Max release to the pressent days and answer is still the same -- Alpha channel can not be displayed through Diffuse. Use Opacity. :)

my actual step:
*******************************************************
manual steps to display an image with transparent areas
1: select a free material
2: set "diffuse color" RGB that will be visible through
the "holes" of the image
3: select Maps->"Diffuse Color", Map-Bitmap->image.tga
4: deselect "Coordinates->Tile U V"
5: select "Standard Map in Viewport"
6: create a plane
7: apply the new material **OK**
*******************************************************
MAXScript to display an image with transparent areas
cc = 2
theBmp = openBitMap "....image.tga"
meditMaterials[cc].shaderType = 2
meditMaterials[cc].diffuse = color 0 196 196 --back color
meditMaterials[cc].diffuseMapEnable = true
meditMaterials[cc].diffuseMap = bitmapTexture()
meditMaterials[cc].diffuseMap.bitmap = theBmp
--meditMaterials[cc].diffuseMap.enabled = true --ERROR--
meditMaterials[cc].diffuseMap.filtering = 0 -- 0:Pyramidal 1:Summed Ara 2:None
meditMaterials[cc].diffuseMap.monoOutput = 1 -- 0:RGB 1:Alpha Channel
meditMaterials[cc].diffuseMap.RGBOutput = 0 -- 0:RGB 1:Alpha
meditMaterials[cc].diffuseMap.apply = true -- 0:crop OFF 1:ON
meditMaterials[cc].diffuseMap.cropPlace = 0 -- 0:Crop 1:Place
meditMaterials[cc].diffuseMap.alphasource = 0 -- 0:Alpha 1:Gray 2:Opaque
meditMaterials[cc].diffuseMap.preMultAlpha = false
meditMaterials[cc].diffuseMap.coordinates.V_Tile = false
meditMaterials[cc].diffuseMap.coordinates.U_Tile = false
meditMaterials[cc].diffuseMap.coordinates.V_Tiling = 1.0
meditMaterials[cc].diffuseMap.coordinates.U_Tiling = 1.0
meditMaterials[cc].diffuseMap.viewImage()
meditMaterials[cc].showInViewport = true
p = plane width:8.0 \
length:2.0 \
pos:[0.0,0.0, 0.010] \
material:meditMaterials[cc]\
showInViewport:true
*******************************************************
at the end, the trasnparent areas will be "black" (the Alpha mask displayed ???)
the only difference in the "Material Editor->Maps" rollout parameters is:
manual =
v Diffuse Color Map#1(image.tga)
MAXScript =
v Diffuse Color Bitmaptexture(image.tga)
*******************************************************
Any suggestions ?
Thanks.
