Hello,
I’ve been looking into this by poking around in blueprints and online, but I haven’t found a solution yet. Perhaps there is someone out there who is trying to do the same thing as me.
I would like to find the hit/collision location on a Geometry Collection in UV space. For static meshes, the “Find Collision UV” works just fine for this, but I don’t know if it would work the same way for a geometry collection.
Basically, I fractured a static mesh with the fracture tools in UE, and created the geometry collection. The geometry collection is simulated with physics and cached with Chaos Cache Manager. I want to draw a cracking pattern render target into the material of that geometry collection based on where it gets hit. Once it is hit several times, the Chaos Cache Collection triggers the animation, and the object falls apart.
In the blueprint, there is a Find Collision UV node that returns a bool (true/false) base on whether or not it was able to find collision UVs. This bool is outputting False when the geometry collection is hit. Which brings me here to double check- is it possible to find the UVs hit location of a geometry collection?
Thanks,
