Help Creating Slavetats

[Leona月]

So, lately I've been looking for a slavetats pack with a Femboy theme to it, I know about the pack from 'Futanemesislol' but was looking for different ones. The thing is, I'm pretty sure there are none others and decided to try my hand at making one myself, so I wanted to ask if there's a guide to get started on this or any tips, thanks in advance :3

 Honestly, if you're familiar with 3d software, easiest way is to load your default body into it and just use texture paint. You get exact preview of the result and no seams. You dont need any fancy software, Blender can do the job just fine (incoming elitists noises). If you're not... well, id still go with TexPaint approach, but there is quite a steep entry curve, at least for Blender. Results must be a .dds file, meaning it might not be exportable as such out of 3d sfotware. Use something like paint.net for conversion. I believe compression should be bc7, for exact colour code so that resulting tat is actually colourable - refer to slavetat page.

Thanks for taking the time to write this up. This is the kind of content I'd like to see more of around the sub.

There are a lot of folks around here that are willing to put a lot of time into modding, and those are the people who are most likely to become our next 'generation' of favorite mod authors down the road. Little write-ups like these do a great job of getting them started on that path.

I tried this guide before but pretty sure I'm doing something wrong, I tried modifying an existing tattoo on gimp and converting the file to DDS later, but when loading the game and trying to apply the tats they would often crash the game. I added the paths on Notepad++ but had to set the language to Json bc it wasn't working as a XML for some reason.

I understand I'm doing something wrong as I'm very much new to this sort of thing, but would be glad to get a bit of help if possible :3

didn't know that doing this with a 3d software was possible, gonna try doing this on blender, I imagine making the tats in a 3d enviroment would be easier than making them on a 2d texture sheet, will probably struggle a bit but was thinking of learning blender for a while and this is a good place to start I think, thanks :3

 Certainly possible, did go that rout myself when wanted to experiment with ST.

As far as i remember - blender doesnt go friendly with .nifs. You can go for outdated plugin, or rather yet - export your body out of Outfit Studio as an .obj or an .fbx, dont exactly remember wich formats are available there. Then import it into blender project.  You can do the same for legs, feet, head etc, if you want texture to seamlessly flow between parts. From there - just follow any of the texture paint tutorials available for Blender.

Could you put a zip file here with the DDS and JSON/XML files inside? I would like to try it to see the cause of the CTD.

The dds image sizes need to be multiples of 512x512 pixels, so 1024x1024, 2048x2048, etc.  You also need to generate mipmaps when you export.  But anyways crashes can be because you're trying to load a texture that isn't a multiple of 512.

Will test it again, but I'm 100% sure it was this since I didn't really check the image size, so I probably ended up messing that up

won't be needed since I found out the cause of the crash was the image size thanks to Wolfen :3, I messed up the image files when editing. Will try again sometime around this week and see if I can manage to load a simple edit, if it works then do you have any tips on making new tattoos? From the looks of it people draw the tat on something like gimp or photoshop and then make it a texture, but I still don't get how tats that span through body parts (both buttcheeks for example) work, since the skin texture is, well, a texture and the butt is all over the place divided into different parts, is there any trick to this?

btw, how do I generate mipmaps?

with Paint.net , configure it as described in the guide I linked to earlier

this is via gimp but, i assume paint.net does it too.  so upon export you need to choose a compression (i use the bc2/dxt3 cause thats what i was told about years ago dont ask me what it means) then you choose the generate mipmaps in the mipmaps tab there.  its my understanding that mipmaps allow the image to be scaleable so even if you have a 512x512 tattoo it will fit a skin texture of 4096x4096 cause the mipmaps allows it to scale.  Dont quote me on that though, i only learned by watching not by understanding things

The texture format depends on what you want. For LE that's either dxt1 or dxt5 if the texture includes an alpha channel. For SE just use BC7, it's a better size/quality format than any of the older ones. Mipmaps are a technique to prerender textures so they scale better at distance. But you can also think of it as a way to trade disk space for better performance.

If you are interested you can try my method for creating slavetats. The only tools I use are mudbox and GIMP. Mudbox is a paid for service, but sometimes university students can get a free 3 year trial (that's how I started using it).

 

If you have another preferred/free modeling program that should work fine too. I prefer mudbox because its pretty user friendly for someone of limited experience. 

 

My tattoo sets can be found here. Included in downloads section is a written guide (might even have some pictures, I don't recall) on my own process for making slavetats.
