Solved Importing Thick Clothes Causes Rendering Issues

When importing even slightly thick clothes, they are not rendered correctly.
Specifically, the edges of the clothes are drawn as if they are double lines.
When the clothes are made thin, they render correctly.
In the attached image, the clothes are worn by the default G2 character.
The clothes were created as an OBJ file in Marvelous Designer, exported to a scene in Daz Studio, and the rendering was correct up to Daz Studio.

If anyone knows the cause, I would appreciate your help.

Solution
This is because the patterns aren't welded at all. You might get away with doing a weld by distance in blender to fix it but you will then be making all new uvs too which becomes troublesome if you laid out your uv islands (patterns) to ease texturing later. Myself I always use the thin welded options on export from Marvelous.

Also, If I could add, Vam do double side cloth rendering, you dont need thickness. Thick will do some clipping even if welded. See in shoot, I have one side
mesh with a fake thickness. Has Juno said You better let Marvelous let weld the thing, if you don't want to mess with UV.

Dear Juno,
Thank you for your prompt response and for explaining the cause.
Am I correct in understanding that in Marvelous Designer, if thick is selected, weld cannot be used?

Exactly that, the other issue with thick mesh is you end up with a double sided mesh and since clothing does not collide with itself the second you enable sim you'll get loads of very much undesired clipping. There is a way you prevent it clipping but it means adding connecting verts between the front and rear faces to prevent the clipping which is somthing I've not yet tried.

The only way I've been able to add actual 3d thickness is to take it to blender and use the extrude and bevel tools on the edges of openings to add hemming but again you will need to create new uvs. And then if you sim an area with 3d hems vam's sim will just destroy them anyway...

Most people just do this via texturing though its subtle compared to a real mesh.

Dear Juno,
Thank you for your prompt response.
I appreciate you providing me with the best solution.
Thanks to you, I have decided to give up on adding thickness to the clothes.
In the case of VaM, I have found that expressing thickness through texturing is the optimal approach.

Glad I could help a bit mate!! I think its worth doing it for things like collars or other parts where there's no sim, the extrude method is the way for that I find. I did this for the collar on the virgin killer dress I made for Christmas.

Wow! What a beautiful dress!
I'll download it and take a look.
Thank you so much for everything you've done for me.
