ldk_renderer_ambient_light_set

Set constant ambient light applied to lit materials. Color uses 0xRRGGBBAA; alpha is ignored. Intensity must be finite and non-negative. Ambient light does not count toward the per-view light limit.

LDK_API bool ldk_renderer_ambient_light_set(
 LDKRenderer *renderer,
 u32 color,
 float intensity
);

ldk_renderer_submit_light

Submit transient world-space lighting. Views need not exist yet. The first 16 matching lights illuminate each view, in submission order. Returns false for invalid data or allocation failure.

LDK_API bool ldk_renderer_submit_light(
 LDKRenderer *renderer,
 const LDKRendererLightSubmit *light
);
