Reply to: @Yaveton I'm curious how the beardless gene is affecting things, I might look into it but there is a high chance I won't be able to fix it. If you ever get screenshots feel free to add them to the Bug Reports discussion I'm about to make!

It's all seems related to the head shape, f.e. in Character Editor I chose narrow-normal head (normal human one due to beardless gene), and the snout was clipping into the head. With furskin there seems to be less variance between heads widths.
Also - middle, colour part has a white outline, that is - if it's slightly clipping into the head, but not nearly as much, there's a while outline. I'd provide SSs but I'm at work :/
@edit: Perhaps it's an easy fix with the outlines - the magic wand tool by accident might've missed the outlines when creating a mask for colour

Chiming in here to say the textures for the body attachments seem to be broken. There was a translucent box covering my colonist that matched their skin color. The problem stopped when I removed the attachments, and they seemed to not appear under the box.

Was it ALL body attachments? I'm not having any problems in my testing environment, so something must be conflicting... Does it happen without my HD re texture too? If you have a small mod list I can try to experiment, but if it's very big I probably won't have the time to look into it.

@Yaveton
I tried some small adjustments in my latest update, hopefully that helped a little? I don't think I'll be able to get it much closer though.

The problem fixed itself.

My mod list unfortunately got to around 800 mods long and doesn't show signs of shrinking so attempting to recreate it perfectly would not be worth it. Might've just been some rendering issues caused by a different mod.
