Texture bit depth

Very new to the program, so please forgive if this is a well worn topic (only found one post when I searched for “bit depth” though). :wink:

So, a little confused about what can and can’t be done in terms of texture bit depth.

The help docs for the SaveImage nodes states “Only 32-bit per channel images are supported”. However, I’ve input a 16-bit PNG and saved out an 8-bit TIF via this node (before I read the docs!), so I’m not sure what to make of this.

Furthermore, when I went to test with a 32-bit TIF to see if it would pass thru, my node graph wouldn’t accept it and showed a hazard triangle next to each node.

So, can anyone clarify what can and can’t be done, and if there is a workflow that can retain at least 16-bit data? There don’t seem to be any bit depth options in any of the image related nodes. Is it possible to output anything except an 8-bit image at the moment?

Hi,

Yes, it’s an error in the doc for the SaveImage node. It should state “32-bit per pixel”. Thanks for noticing!

Currently, we are working on adding a 32-bit depth per channel support for Wrap. For now, only ZWrap supports 32-bpc images, and mostly for 3-/4-channel images.
