Title: Stupid question about transparency
Post by: Jpjapers on 2017-06-20, 11:03:01
Such a brainfart moment but max standard materials have always confused me with regards to transparency.
Occasionally i figure out how to make use of PNG transparency in a standard texture but then i go back and try again a few days later and i cant figure out what i did. Its such a simple thing but i can never remember how to get max to show PNG with transparency in the mat editor.

Help?

The (bit)map itself never shows with transparency afaik ("Show End Result" toggle off), how did you do this? :) Or do you mean just the preview? I would load PNG as diffuse, set Mono Channel Output to "Alpha" (maybe this is what you are missing?), and put an instance in the opacity slot. Viewport preview works also perfectly this way (Max2016 here).


Good Luck

I think you need to use a Standard mat and turn on 'show realistic materials' in both the material and the viewport. Not sure though!

1.Turn on transparent for materials in viewport/
2.Turn on view material in viewport in MAIN material menu /not for map/!!!
3.Set Alpha channel/Mono channel/Rgb channel///
4.Make sure if Alpha is exist in loading bitmap file via View Image menu///
This must working with ALL materials type, not only with Standart max material
