Hello!
I’ve been playing around with the Houdini Engine for Unreal and I really like it! One issue that I’m currently having, however, is that when I store the Alpha attribute (on points, vertices, or primitives), this doesn’t transfer as opacity to the Unreal Engine (or maybe I’m looking in the wrong places; it doesn’t seem to update the opacity in the viewport for sure). This is confusing to me because Cd does properly transfer. According to this documentation, Alpha should properly transfer.
The only work around I’ve found is to store the Alpha on Cd instead and then pull it into an Unreal material to drive the opacity:
This is problematic because I will need the Cd to store color information, not opacity information. What am I missing here?
Thanks!
