Description

When Uploading Textures either directly through the image upload option, going through bulk upload (which allows automatic downscaling of 4k textures) the end result is a low resolution blurry texture.

The same upload works fine on Firestorm and Official Viewer

Reproduction steps

1. Upload texture on recent Alchemy version
2. check how sharp the texture is
3. compare with results by other viewers

[Quinn-Elara]

You should provide a copy of the raw texture in question to assist in debugging.

Also, sidenote: Relying on any viewer for downscaling is not recommended. Your image editor of choice will do a much better job of downscaling a texture for use in SL (be it 2048, 1024, 512, etc). (This is not likely to be related to the bug in question, but if you want the best quality textures in SL, this is good practice).

the issue is the same regardless of downscaling by bulk upload or giving a 2k version directly through image upload.

The GLTF uploading path is unaffected which I forgot to mention earlier. That one worked correctly in my testing.

I must report a correction: GLTF upload suffers from the same low resolution. I just attempted another upload and the result is unusable. As creator... serious problem
