Cool VL Viewer forum

Hello there,
i am really new to this viewer, but not new to SL.
I am searching like mad how to get that checkbox working for uploading a texture with lossless compression. I tried .jpg, .png, .tga, nothing....the checkbox is greyed out.
I tried 512x512, 1024x1024...almost every size you can imagine.

What do i wrong?

Loss-less compression is only available for small images, which surface is smaller than or equal to 16384 pixels (e.g. 128x128), which is only really useful for sculpty textures. It's always been the case...
