Yes, the obj file can be imported. Strange that they did not add the last step to it. The created cr2 contains the obj reference, but does not use it and does not attach the materials. I hope it will be corrected in the new :“heavenly” import
Another thing which I discoved: Some items break after being exported (such as the wings for Strogoi vampire). It breaks as soon as you conform. I wonder if that is one of those mismatched end points, but I could not find them. Parenting does not work here since the wings move with the arms, which is a petty since they look very good.
Shoes are another department where things go pretty bad when exported. Somehow they seem to deform. Scaling does hot help here. The deformation seems to get worse if V5, M5 or S5 morphs are used.
What really worries me is the S5 (and in lesser extend V5 and M5) looks really awful at places (prime example is the knees). There is so much distortion here that it is no longer usable in Poser. If you look at the base mesh view in DS4 you can see that the base itself is malformed. High res is a bit better and when rendered does not look good either. In Poser - even with all smoothing on - it looks really bad
