RTLights for Quake

A collection of rtlight and cubemap files for Quake engines that support real-time lighting such as Darkplaces and FTE Quake.

Installation

Each release has a pre-compiled pk3 file that can be placed directly into the corresponding mod directory, e.g., id1.

Alternatively you can place individual .rtlights files into the appropriate mod/maps directory, and cubemaps into the mod/cubemaps/ directory.

Usage

Settings

Once you have your maps properly VIS'd, launch DarkPlaces and turn on real-time lighting, either via the menus:

Options
- Customize Lighting
  - RT DLights: On
  - RT DLight Shadows: On
  - RT World: On
- Customize Effects
  - Water Alpha (opacity): 0.7

or via the console (~):

r_shadow_realtime_dlight 1
r_shadow_realtime_dlight_shadows 1
r_shadow_realtime_world 1
r_wateralpha 0.7

Arcane Dimensions

Because the map sources are available for Arcane Dimensions maps, some have been re-lit with a combination of light-maps (.lit file) and real-time lighting (.rtlights file). For these maps, both the real-time world shadows and world light-maps should be enabled via the menu:

Options
- Customize Lighting
  - RT World: On
  - RT World Lightmaps: 1

or via the console (~)

r_shadow_realtime_world_lightmaps 1
r_shadow_realtime_world_shadows 1
