Add Normal to Existing CAS Accessory That Doesn't Have One?

You can make it with DDS plugin or by using any software that creates normal map, for example Njob. Your biggest challenge will be to figure out a propper size for it. For example bump map of clothes is 1024x1024 (doesn't need to be doubled for HQ settings), but hats NM has to be 512x256 and has to have only texture from hat area. I would recommend cropping it to 1024x1024 first, then 1024x512 and see if it works. And for checking I would recommend importing a plain swatch, this way you will be able to see is NM is for sure working.

For example this is how one of my earrings with this plain texture look in Studio (Studio doesn't read normal map) (on the right ), and on the left how they look in the game. It is difficult to see it with the real texture.

Tried 1024x1024 and 512x512 but couldn't get anything to show up. Tried it on the original glasses I cloned as well no dice. I've been on this particular very small accessory for over a week now so I suppose I'll just be painting it in manually to get it finished already. Too bad I used the method from Tea 'n Moon's tutorial for a set of paintings I did and it worked so well. This is why I don't do CAS items lol. Thanks anyway.

I noticed that as well when you upload a normal in the texture/studio tab, then it populates those fields in the normal map section of CASpart. But the group, instance, and type are already populated with numbers so what am I supposed to be inputting? Each CASpart has the same numbers in the group, instance, and type fields.

I honestly feel like this might be just one of those dumb things. I looked at all the existing glasses and some cc glasses and they all hand painted shadow/highlight directly onto the diffuse itself no normals to be found. I also noticed their uvmaps were super simple rectangles that makes hand painting really simple which I cannot figure out. I assume this is something blender maybe can't do:

I've tried all the unwrap options in blender but none of them do this type of map they all give me a map of the shape I've made that is complex and really hard to hand paint and I have a cintiq and wacom tablet lol. I know I'm going off on a tangent here but I really do research and try really really hard to figure this stuff out and this is the hardest thing I've ever come across. Everything has gone wrong like ten thousand times and I've remodelled, retopologized, remapped, repainted over and over and over and over and I just want to throw it out but they actually look really good in game I've got so close. This is the second attempt too I started this last fall and scrapped it when I couldn't figure out how to wrap the mesh around the head properly. Sigh anyway mini rant over I appreciate the help though thank you both
