georgeng,
In the metaball hlsl, change View.ViewOrigin to View.WorldViewOrigin
I found that reading the youtube comments on the livestream but I believe in the stream they mention that the safest thing is to add an input to the function for calls like that because it’s not uncommon for them to change the naming in the engine.
Hopefully you’ve solved it by now since you asked in October but if not, that’s your answer
