Parallax Occlusion Mapping NME incorrect height

Bugs
1

Hey there!

I am experimenting with POM in NME and noticed that the “parallaxHeight” input of “Perturb normal” seems to be ignored. Instead, it seems the height comes from the alpha channel of the normal map, which is not obvious given we only pass the RGB channels to the block.

Is this a bug? I wanted to use a separate texture for the height map but it does not seem to work:

While this one works (I believe height data is stored in the alpha channel)
