Creating and editing .rtlights: Part 1: The Basic Commands r_editlights "1" This enables the "editing" mode where you can actually see and edit the different points of light created by the .rtlights render. r_editlights_edit origin x y z This allows you to edit the highlighted points (whichever one the hud displays in the upper left hand corner) origin x-y are left and right, fowards and backwards, z is the height and depth r_editlights_edit color r g b This allows you to edit the color of the highlighted point, if your cubemaps have color to them you may want to make the light more "white" by evening out the numbers, ie a blue light 0 0 1 should be made light blue .6 .6 1 r_editlights_edit radius 'radius' This allows you to edit the radius of light of the highlighted point projects, this has a large impact on performance r_editlights_edit corona 0-1 This allows you to enable disable a corona, a corona will automatically be the same color as the light you attach it too r_editlights_edit coronasize 1-x This allows you to edit the coronas size in coorilation with its origin light's radius. r_editlights_edit cubemap "folder/cubemapname" Cubemaps will have to have 6 parts I will use my 01 cubemap for an example 01dn 01up 01rt 01lf 01fr 01bk. Can be rotated by using r_editlights_edit angles r_editlights_edit angles x y z Rotates the light (imagine it as a cube, not a point) the only useful purpose is to properly set cubemaps (or if you are feeling artistic offset them a little to fake directional light) r_editlights_edit ambient "1" Defaulted to 1, affects the reaction the light will have to bump/glossmaps. r_editlights_edit specular "1" Defaulted to 1, affects the reaction the light will have to bump/glossmaps. r_editlights_edit defuse "1" Defaulted to 1, affects the reaction the light will have to bump/glossmaps. r_editlights_edit normalmode "yes, no" If you want the light to show up in normal render, you can select it to do such, this is nice for cubemaps other than the cones (because the cones show up anyways) r_editlights_edit shadows "yes, no" Defaulted to 1, this will make the light shadow casting or non shadow casting, this is purely in stencil shadow related (ie the "projection" from cubemaps will show up no matter this setting) , i found it very helpful to make small lights non shadow casting to speed things up, it also allows you to put in a little more detail without alot of slowdown
