Glb/glTF Does not store all material attributes.

[MarKli]

 

These attributes are not saved under Material:

Intensity
Transparent
Alpha mask
Two-Side
Displacement
Offset

The color intensity is a value that gets calculated from the color, and saved back as the color. It won't appear separately in the glTF file. For example, if the material color is (2, 1, 1, 1) then the intensity in the editor will show 200 and the color will be displayed as (1, 0.5, 0.5, 1).

Although Ultra treats alpha blending and alpha masking separately, in the glTF format they are two different settings for the alphaMode value, so they cannot both exist in the same material in a glTF file. (This is fine, as you would never want to use them together.)

I did some fine-tuning and I believe the issues are fixed in the editor glTF save feature.

Properties that are only supported by Ultra get saved in the glTF material "extras" field.
