How does one give say a new mutation you have made a visual?

Like say i have a mutation that i want to look like an item (Say one of the many wearable tail items that can be found in mods or something.)

How would i tie said appearance in a tileset to said mutation.

I am trying to make a saiyan tail currently and would like to use the Fur cat tail in UDP, but i don’t know how i would give it that appearance in the tileset, any help would be appreciated.

You’d have to define a `"id": "overlay_female_mutation_`[MUTATION NAME]`"` and/or `"id": "overlay_male_mutation_`[MUTATION NAME]`"` in the tileset, see the [UltiCa tile\_config.json file](https://github.com/CleverRaven/Cataclysm-DDA/tree/3c13759cc459e454459437ee1f735ce6af021914/gfx/UltimateCataclysm/tile_config.json#L4556-L4557) for an example on how it’s done.

The question is, do you want to make a hole tileset or just add it in with a mod?  
If it’s the latter, you might want to take a look at how the “monster sees player” overlays are added in [via a mod](https://github.com/CleverRaven/Cataclysm-DDA/tree/3c13759cc459e454459437ee1f735ce6af021914/data/mods/sees_player_retro) for some of the tilesets.

Thank you! I managed to figure out how to give the mutation an overlay so its working properly! I appreciate the assistance.
