FBX Review: No Opacity?

[Anonymous]

Hi, how do I show the opacity in the viewer?

Setup:

Software: 3dsmax 2017

Material: Standard Material

Diffuse Map: JPEG (Random Texture)

Opacity Map: JPEG (Black and White Mask)

Object: Default Box

Export:

• FBX -> Autodesk Media & Entertainment preset
• Plugin Version: 2017.1 Release (244292)

Result:

Opacity is not visible..

Finally got it to work. But I'm not sure about the extents of how other variations of this workflow can work. But below is what worked on my end.

Texture Setup:

• I used TGA.
• In Photoshop:
  • TGA Options should be 32 bits/pixel to have Alpha channel.
  • Don't use Compress (RLE)
• Make sure you added an Alpha Channel layer in the Channels window.

3dsmax Setup:

• Instance your standard material's diffuse map to your opacity map.
• Bitmap Texture settings:
  • Mono Channel Output: Alpha
  • RGB Channel Output: RGB
  • Alpha Source: Image Alpha

Export:

• Use FBX > Autodesk Media & Entertainment preset.

Opacity now works!
