If that card is referring to what I think it is, then it’s a completely different purpose. I believe that’s meant for actual animated objects imported from other tools, whereas the RMC (and the PMC it’s meant to replace) are meant for being able to generate meshes at runtime to do things like procedural terrain, buildings, objects, or to be able to load a mesh from a raw model file at runtime when you don’t have editor support. The RMC is just efficient enough that it can do some limited real-time vertex animation like that sine/cosine wave powered plane in my original example.
