FBX Importing Skin weights from maya?

Hello, I have an FBX file I have imported from Maya. It work mostly, but all the weights are only 100% bound to a bone. When I view the file in quicktimes FBX viewer it looks fine, but not in unity.

I can’t find any import settings for this either.

Of course. Every vertex can be bound to 4 bones. The resulting weight is normalized and will always be 1.0.

A simple example with 2 bones:

a vertex is bound with 1.0 to bone1 and with 9.0 to bone2 the resulting weights are:

bone1: 0.1
bone2: 0.9

If you bind a vertex to only one bone it will always have 1.0 weight since it’s the only “thing” that affects the vertex.
