Until recently, I didn't encounter any issues exporting characters from CC4 to FBX and importing them into Maya.

However, at some point, I started experiencing problems with the character's facial expressions.

When transferring the character to Maya, I utilized InstaLOD's Merge Material function to combine the materials.

Previously, this process worked flawlessly without any complications.

However, at some point, the character's facial expressions stopped functioning correctly when using InstaLOD.

If I simply export the character to FBX without utilizing InstaLOD's Merge Material feature, there are no issues.

But when exporting with InstaLOD's Merge Material feature, the character's facial expression blend shapes fail to work properly.

Additionally, adjusting the blend shape values in Maya causes the character's body to shrink.
