About this mod
Replaces the luminance textures of the SeaMoth with modified ones (with help of the "Texture Replacer" mod)
- Requirements
- Permissions and credits

A small texture mod that includes 2048 x 2048 luminance textures which are in the same resolution as the main texture files (original _illum.pngs are in half resolution). In the opional file the exterior lights are brighter and the cockpit is always lit (see pictures taken at night).
Installation:

Configuration:
If you would like to edit the glow strength and base texture brightness (lit cockpit at night), the .json file is pretty much self explanatory.
- _GlowStrength (default: 1.94)
- _GlowStrengthNight (default: 1.94)
- _EmissionLM (base texture brightness; default: 0)
- _EmissionLMNight (base texture brightness night; default: 0)
- SeaMoth_illum: exterior lights
- SeaMoth_indoor_illum: ceiling lamps, cockpit brightness. back top part
- FlapL_illum: left tail light
- FlapR_illum: right tail light
- ModuleCover_illum: little bulb on the module storage lid
- PowerCell_illum: normal powercell
- PowerCell_ion_illum: ion powercell
- Interior_SeaMoth_illum: Seat
- Interior_SeaMoth_indoor_illum: Dashboard, wheel, cockpit brightness. main part
If you need a detailed explanation: Indigocoder's tutorial Custom Configs (Legacy! but is possibly still the same) or watch Leviathankraken's video (link at the bottom)
I use Sublime Text to edit json files
Versions in FILES tab:

- SeaMoth_texture_mod (includes only the dashboard visible while driving, original textures)
Optional
- AschisMoth_texture_mod (adds exterior tweaks)
- PRAWN_texture_mod (extra. incomplete! see pictures)
Miscellaneous

SeaMoth texture changes:
Interior
- Dashboard (green displays left and right in front)

Optional files
Interior
- Seat (Tilt adjuster? hinge?)
- Ceiling lights (3 fluorescent tubes on both sides behind the seat)
- Back wall light (circle behind the seat)
Exterior
- Headlamps (+glow to the casing added)
- Roof light
- Taillight (rudder(or flap in gamefiles) that only opens during maneuvering)
- Turbine Glow (electric motor heat? some red to give contrast)
- Propeller light
Less prominent
- Intake (indirect lighting inside the front grill)
- Module cover
- Powercell (ion too)
- Turbine vanes (blades) and casing (again, not sure if red makes a lot of sense, mostly for aesthetic reasons)
- Propeller indirect lighting (not sure if this looks good with its high specularity, is in original png though)
- Headlamps under the left rudder (l_flap_jnt, Submersible_seaMoth_flap_R_geo), only visible in third person while maneuvering
PRAWN texture changes (incomplete):
Interior
- Handle displays
Thanks
- Indigocoder for the mods Texture Replacer and Texture Replacer Editor. It was a great help to see changes without restarting the game and tweaking settings in-game with generated configs.
