For some reason, genitals shells are not loading correctly, they show in the render higlighted in red. This happens both with Golden Palace and Advanced Pussy Redux.With Futalicious, it just doesn't render the texture. Turning off the shell visibility doesn't change anything. Have i messed up some setting by mistake, or should i reinstall everything?
This is how it looks: 
Edit: found the issue. in Tool Settings, i had "node weight map brush" instead of "Universal" as the active tool.
