Pipet (Stride) doesn't like negative colors

I’m trying to sample negative colors and pipet outputs NAN

can you elaborate on the idea of “negative colors” and maybe add a patch that shows this?

Another idea, have you tried reading back Vector4 instead of RGBA?

I just tried the readbacked output, but it looks the rgba conversion is doing funky stuff.
I’ll try to read vector4 instead and report.

I have seen this, I was outputting vector3 (and this seems new since 4 as I didnt see this error until starting porting it to 5)

Interesting, it seems the rgba join / split are behaving a bit weird, I remember having other issues doing value to color conversion and vice versa.
I’ll check it out.
