Using Unreal variables inside Houdini Engine

Показать описание
Came up with a way to transfer arbitrary user variables from Unreal actors to Houdini engine, which can be quite useful. Not sure if this is a common technique but I though i'd make it into a tutorial because I didn't see anything else about it online.

Hey Tim, thank you for this great tutorial! It's awesome to have it because there's a lack of good content on YouTube about deep Houdini Engine features.

I was wondering if you know how we can create multiple material instances for generated mesh in Houdini.

Basically I'm facing this problem:
I'm trying to figure out how to create multiple material instances from one master material. Basically, I'm using "unreal_material_instance" for different meshes that reference my master material Additionally, I am also using to control one of the material instance parameters.

However, no matter how hard I try, I can't seem to create more than one material instance at a time. What happens is that if I have two objects referencing my master material and I set different values in Unreal Engine, only one material instance appears with the value of one of my objects, and the same material instance is applied to the second one.

why are transformer handles so weird? rotations are way off between houdini and unreal. when I use the TRS gizmo in unreal doing a 10° rotation will result as a 573° input for houdini. "solving" it by dividing by 57.3 in my transform but it feels bad and wrong to do that. would love to see a vid on using handles!
