Can't repeat the error. This is V3 with DAZ hi-res textures. I didn't alter the base texture so the trans-eyebrows sit over the brows on that, coloured yellow for clarity. The transmap for the brows came with the DAZ hi-res textures. No problems with the eyes either.

V3 exported as OBJ from Poser4; imported into Bryce5 (not DAZ 5.5).

On yours I still suspect some corruption to the model during export-import. It doesn't look like a transmap issue - too even around mesh.
