Hello,
I saw this today and wanted to ask why we should avoid to use JPEG files for displacement source?

"For texture displacement, this needs to be an image.
This means you can put a PNG, EXR, PSD, or any other image type supported
by octane into an Image Texture node and feed it into the displacement node
(avoid JPEG though if you can)."

Corrupted pixels because of image compression and 8-bit colors. It works best with 16/32 images.

Thank you elska (nice blog) and aoktar.

Does using JPEG effects visual result only, or it effects render performance too?

And what about format for HDRI Skies ? Is that true that HDR format is better than EXR for them ?
