Various issues with exporting from Blender using the ED plugin

[Homelander]

Dear Community,

Every time I export a 3D model from Blender [currently: Blender 4.2.1 LTS] using the official Blender plugin from ED [currently: edm_tools_blender_plugin-241504.zip], I encounter the following issues:

• The Roughmet texture is not listed under textures in the model viewer.

• The textures in the model viewer are simply scaled down. Normally, the main texture (excluding glass surfaces) has a resolution of 4096 x 4096.

• When I check the mapping box, the UV map does not appear.

• In the model viewer, mipmaps are scaled down, causing the UV map to no longer align with the texture, resulting in red edges (red is used for visualization).

Section of the uv-map in blender:

In my graphics software, I have extended the borders by 8 pixels around the UV seams to allow for enough tolerance.

Seam margin of 8 Pixel (vector graphics program):

When I zoom out on my model in Blender, no red edges are visible, meaning the UV map and textures match.
The exact same issue occurs with all other 3D models I’ve exported from Blender.

I suspect an error with the export plugin. Can anyone explain why these errors are occurring?

Thank you in advance.
