Two Translucent material in one Skeletal Mesh has Z-order problem

Hi!

I has a fish skeletal Mesh that has two materials on it.

Body and Fins

They are both “Translucent” Blend Mode.

The pectoral fin of the other side is seen, which is not supposed to be.

And the beak of the fish also has z-order problem.

How can I solve this kind of situation?

I think the easiest way is to split your material in 2 materials, opaque and translucent. Darn, no one knows nothing about z-order. Hope you’ll solve it in some way
