Ugly Skin Texture Seams On Imported Genesis 8.1 Female Character Imported Into UE5 with DazToUnreal

Why do I keep getting these ugly seams on Genesis 8.1 Female when I import it into Unreal Engine 5 using DazToUnreal?  I used version 5.0.0.71 of the DazToUnreal UE5 plugin I got from here.  Looks like there is something wrong with the UV mapping.

    Could be a few things. The look of the seams suggests to me it could be an issue of texture streaming pool size. More information here (wonderful video):

    An easy way to fix it would be to press the tilde key (`) and enter the command:    r.Streaming.PoolSize 3500

     

    If that doesn't fix it, then it would be helpful to know what specific Daz skin textures you are using on the character. Genesis 8.1 has different material zones than Genesis 8. In G8.1, the head material zone is it's own thing and requires its own textures, in G8 the torso and head material use the same texture. So, if you are using Genesis 8 skin textures on Genesis 8.1, the head material zone will be incorrect in Unreal. You can use the Map Transfer tool in Daz to create head textures from any G8 torso texture. Again, this will only apply if you are trying to use G8 skin on G8.1.

    It is also happening with Genesis 8 Female imports into UE5, not just 8.1

    I ran into no issues when I tried importing both G8F and G8.1F into UE4.27

    The red warning message in the upper left corner appears to be notifying you that you are over-budget in your texture streaming pool. You can disable it with the command "r.streaming.poolsize 0" (no quotes). It is meant to add to efficiency, however the intial memory allocation (1000mb) is quite low. Either increase the number to something like 3500 or disable it by entering 0.

    I installed the latest version of DAZToUnreal plugin for UE5 from Dave's github page and that seems to have fixed the issue.

    This is also happening to me and I have no idea how to fix it. Gen8 models.

    2 years to late but in Modern Unreal 5.3 when importing from Daz if you have virtual texture streaming enabled this will happen to your models.

    a quick fix is to go to project settings and look up your "Auto Virtual Texturing Size".. Set it to something like 8k Import your model and textures and all should work. Alternatively you can go into the textures folder for the model and open each texture and deselect the Use virtual texturing option.

    You will get full quality for the model. I am ansure how to make virtual texturing not destroy my textures other than this method. Virtual texturing is great for landscapes etc but I want my primary character model to be crisp at all times.
