Low Resolution exports for glTF files

[Cafernxd_Skanska]

I’m having trouble exporting certain models or scenes as a glTF file. I’m testing the glTF exported found in Marketplace and on some models, the textures seem to bake out into a very low-resolution image for no noticeable reason.

• The exact format of the export is .glb

• I’ve tried different models both unwrapped or UV tiled, results vary

• I’ve tried different material setups as well as megascans, results vary

• On export I tried both material override and default settings

I was hoping that If I could get some insight into what is happening with uploaded images, I could figure out a solution. Any help would help tremendously, thanks in advance for the time.

Hello @Cafernxd_Skanska,
the dev has a few ideas about the issue but could you share the uassets of the models, material and textures or the project even with us so we double check.

You can send them to me through private messages or I can send you a link to a box folder if you need a place to upload it.

I also had the same problem, after lots of testing, i figure it out.
Berofe export convert textures to normal texture from the Virtual texture:

i found another way, changing VT tiles sizes values increase export quality:
