Worked: (optional)

Short description of error
UV textures work fine when particles children are in Interpolated mode. But when I switch to simple mode (Due to another bug), they turn black.
When I switch to other coordinates like Generated or Object, it actually produces the right colors, but obviously not in the correct places.
Even tried to bypass the problem with baking the textures to vertex colors, and even then it didn't work.
Everything with SSS produces the same bug as well.

Exact steps for others to reproduce the error
Just switch between Interpolated and Simple.

Provided a blend file, Apparently, when I try to reproduce the same steps on a simple monkey it works fine.

Sebastian Parborg (zeddb) triaged this task as Confirmed, Medium priority.

It seems to work fine with eevee so I guessing this might be a cycles issue.
