1. use word pad to edit (not note pad else will not work)
2. Open..... C:\Program Files\1C\Eagle Dynamics\Ka-50\Scripts\Aircrafts\Ka-50\Cockpit\materials.lua
3. Add a new material at the top of the materials section--- ie....
materials["JPGREEN"] = {156, 249, 204, 255}
the numbers are.... Red,Green,Blue,Alpha (Note u can change the alpha if you want)
4. Open.... C:\Program Files\1C\Eagle Dynamics\Ka-50\Scripts\Aircrafts\Ka-50\Cockpit\HUD\HUD_init.lua
5. edit the following line to your new colour name...
indication_color = get_color(materials["JPGREEN"])
Thats it - will not have new colour in the game - most important bit is not to use notepad and DO use WordPad
Cheers
