Hi n00854180t this is looking really good. I’ve been in several discussions about this topic myself and have plans to implement a Gore System using several techniques: Left 4 Dead, SoF GHOUL, Destructible/Fracture Meshes, and Collage Construction. I’m aiming for a Gore system suitable for a multitude of creatures of various shape and limb count. Perhaps use it to pull a similar effect to Mortal Kombat X Ray Attacks.
I’m under the impression L4D exterior wounds are 100% vertex shader manipulation with all the needed transparency, depth etc, to simulate filler ‘caps’ for the internals. There is no mesh swapping or spawning. I purchased the Advance Dissolve FX Kit for this purpose.
Your character appears to have separate clothing meshes. I believe L4D using single mesh body (base body + clothing). I would anticipate the technique being applicable to modular base body and clothing pieces, but I’m curious as to how you’re going to approach it.
