Light Bleeds through, and other questions

I'm working on modeling some fedoras for DAZ, I'm modeling them in 3D Studio Max and exporting them as an OBJ and importing that into DAZ Studio 4.6.2.

The problem I'm having is that when the hat is close to the genesis figure there is light bleeding through the hat to genesis, as you can see in first picture. There is no poke through of the genesis head as you can see in second picture, you can even see a gap between the head and the hat when you get close.

If I raise up the hat you can see that it the hat is solid, as in the third picture.

The only thing I can figure is that, even through there is a gap that DAZ thinks that the head is close enough to let light through even though there is no poke through either on DAZ or in 3DS Max.

I would greatly appreciate any idea for fixing this issue and thank you in advance! :-)

Additionally, does anyone have suggestion for using the transfer utility for hats? The only thing that comes to mind is 'Hair > Short'. Or should I just parent it to the head?

Also, does anyone have any idea why surface diffuse opacity is set to zero when importing a .obj? I was quite confused the first time I imported on and it didn't appear in my scene.

    Check your normals...and surface settings. If diffuse is coming in messed up, something else could be, too.

    Normals all look good. I've included a screen shot of the 3DS Max .obj export. There is an option to include normals the export and another to optimize normals. I've tried it all four different ways, both checked, first one only, second one only and neither checked. All results were the same.

    As a side note, I've imported quite a few .obj's from 3DS Max into DAZ and the opacity setting for all of them have been at zero - which probably means that I have a setting wrong somewhere.

    For the light bleed-through problem have a look at the 'shadow bias' on the light - I think distant lights default to 1.0 (so the shadow ray test starts one unit out from the surface) so I usually set it to 0.1 or 0.05.

    I agree, that looks like shadow bias - that's an offset, in cm, so with something close fitting like a hat or hosiery it can easily be too high to work.

    And there was much rejoicing!! :cheese:

    It was shadow bias, toned it down and everything looks good now.

    Thank you to all those who took the time to look!
