Question: normals extraction with relight-cli, colors seem off?

Hi,

I have extracted normal maps for my data (using -n option) and the exported RGB normal maps don't look correct. They are mostly pink. When visualizing the same data with relight, the normal layer visualization makes more sense. So I'm wondering if this is a problem of the data (input colorspace?) and/or is there something going wrong in relight-cli normal image writing?

Thanks!

It was a problem with the output colorspace (trying to conform to a different standard). In the meanwhile I improved the normals quality too.

Yes, looks better. Even though to me it still looks as if the green channel were reversed with the red one.

Red channel is on the X axis and Green channel is on the Y axis, RGB -> XYZ

I'm not really sure this is the correct standard...
