HDA have problems with HF Masks (?)

Hello

I was confused to see that the Heightfield masks are reacting badly when imported as HDA into Unreal Engine.
So I made this little test.

First mask > Cube
Second mask > Sphere
Third mask > Squid

When you check the Layers Debug in Unreal you can notice they all get transparent when they overlap.

Expected behavior would be:

Option 1: they substract each other by order
Option 2: they stay at 100% where they overlap

But like this it's very difficult to manage the masks except if we do the substraction operations in Houdini but it gets quiet complicate when you have lots of layers to manage.

Please let me know if there is a better way to get the masks correctly.

Thank you.
