Ok. Loaded up M4, spawned the morph target based on your OBJ file, flipped on the brow prop, and everything looks fine on my end.
(from here, personally, I would save the CR2 with binary morphs on, then use Binary Morph Editor to create the inj/rem scripts with the PMD data saved right to the inj/rem files, but that’s just my personal workflow)
I went a step further and did my inj/rem creation just to test and it works fine. It seems to be something in whatever whichever one of you is doing, since I’m working from the same morphed obj as you.
