Import Morph Targets without Skeleton?

I have very simple morph targets on attachment meshes that I attach to my main character. Is it a requirement that I need to have that mesh connected to a skeleton and physics assets in order to import/use the morph targets?

There is a 3DS Max plugin to allow import of morph targets for static meshes, but it’s much easier just to add a single bone to your static mesh.

You’d have to re-write half the engine, but it is possible.
Look into the ABZÛ gdc talks.

Otherwise, the max script is really just a material.
You can use a material to displace vertex as a morph target would, but you’d have to code or come up with a way to do it by associating vertex to a specific UV map.
It’s easy to solve for the engine / incredibly complex to set up.
Hardly worth the time involved really.

You can have 1 or 2 morph targets on a static mesh using this method:
It’s more performant than using a skeletal mesh.
