No Missing Gene Icons Mod automatically generates missing icons for ChemicalDefs so they no longer display the default “missing texture” icon when converted into genes. It ensures that addiction and resistance genes created from custom chemicals have proper visuals instead of error placeholders.
No Missing Gene Icons Mod Features
- Automatic icon generation: Creates missing icons for genes derived from ChemicalDefs at game start.
- Prevents error textures: Stops genes from displaying the default missing texture icon the first time they appear.
- Smart icon composition: Uses the default drug gene icon as a base and overlays it with the icon of the first registered drug using that chemical.
- Full chemical support: Works with all added chemicals that generate addiction and resistance genes.
- Additional compatibility: Supports regular addiction genes added by Gene Extractor Tiers.
Compatibility notes
This mod iterates through all chemicals on game start to validate and generate missing gene icons as needed.
