This technology for aircraft developers allows efficient, variable, and clear cockpit lighting.

The Experience

Technical Information

The RealLight technology integrates into the model of the aircraft directly. It also allows for complete customization of the lighting intensity and behavior.
Using local variables (L:Vars) specified in the RealLight configuration file, night lighting textures can be used and blended on the fly to create full cockpit lighting with minimal to no code required by the developer.

TFDi Design does not require access to the source model, but the developer implementing RealLight into the aircraft does.

Note: RealLight does NOT create dynamic 3D shadows of cockpit parts.
