Hi Team, I tried latest 3dmax 2018 exporter v20181220.1 to export a glb file. Physical Material and Standard material with transparency/opacity properties can’t be exported correctly. But the earlier versions say v20190801.8 works well.
I ran into the same problem and tested it many times. The physical material doesn’t export transparent material like glass. The standard material has to use a blend mode after adjusting the transparency parameters, but it doesn’t work very well
