Pivot Painter version 2.0 will not export hierarchy structure properly.

I know that hierarchy information will be written in the alpha channel.

But actually, both 2 textures which is exported from Pivot painter tool don’t have hierarchy (or each of object size) information at the alpha channels. Those are all black color nad nothing.

I obeyed the official EpicGames document, and chose one of bottom of hierarchy part( a leaf part of the plant model) in the 3dsmax version 2027, then export 2 textures. But couldn’t get hierarchy info at the alpha source. Why?

According to official document, EpicGames didn’t test it in 3dsmax 2017 and newer version. (Not solved at all)
