Opacity Map in W3D

[Kyungjin]

Hi, everyone.
I just have a question about opacity map.
Does Director support opacity mapping ? I applied two jpegs on a 3d object in
3D Max ver 5 to reduce no. of polygons. A tree image for diffuse map and B/W
image of the tree for opacity map so i can see just tree without background of
the tree in 3D Max. But I see everyting including background in W3D file after
exporting. It seems Director doesn't support opacity map.
If anyknow this, answer will be really helpful for me.
Thank you.

Shockwave 3D does support opacity maps.

Your 8 bit opacity map must be in a 32 bit texture (TGA, TIFF, PNG, PSD...).

You must also set the texture render format to 32 bits (#RGBA8888) in Lingo or
use the Chrome Lib for this purpose:

To be more explicit, create a 32 bit texture image with:
the 24 bit texture + the 8 bit opacity mask

Map it then export the W3D file.

You can then set the texture render format.

Thank you. It does work.

I really appreciate.
