Ease of exposing mesh vertices in unreal

kirkkh

General idea/guide on how I should go about doing that? Looking for individual vertex control (whether in BP or C++). Apologies if duplicate post, didn't see anything in the runtimes doc for UE4.

Could you give us an idea what you want to do? In general, you can access the spine::Skeleton of a SpineSkeletonAnimationComponent. That has the attachments that contain the vertices.

I have some procedural animation driven by the game's logic. Wasn't exactly sure the best way to go about that, both for bone and vertex control. I know that Spine in UE4 needs some 3rd party state machine support (I wouldn't feel confident designing my own stat machine logic)

I'm just fuzzy about proper referencing. A vid tutorial would by ideal, but I'll take any documentation or tips. Thank you so much for your reply btw 🙂

I guess the easiest approach would be to use the SpineSkeletonDriverComponent, see Spine-UE4 Runtime Documentation: Skeleton Driver Component. That won't let you control individual vertices directly, but you have full control over bones. Pairing that with your state machine should be easy enough.

Controlling individual vertices will be a lot harder. I'm afraid we don't have a UE4 specific tutorial for that.

Thank you so much, I'll keep cracking at it

just to double check controlling vertices at run time is technically possible?

Mario

Technically yes, but it's not straight forward.

Thank you (again) 🙂
