Create Fire Lights | emLightsCountEnbl – When enabled, allows the fire to shine on smoke and on surrounding objects in the scene even without using Global Illumination (GI). With GI, the fire will automatically illuminate the other scene objects and the simulator's own smoke, but the rendering will take quite long. Enabling Create Fire Lights simulates GI by placing light sources in the bright parts of the fire, which produces similar results and renders much faster.

The parameters below control how many rays have to be traced in order to calculate the lighting. The larger the ray count, the better looking the result will be, but it will render more slowly. For general explanation of how light sampling works, see the V-Ray Image Sampler page. |
Direct Subdivs | emLightsSubdivs – Sampling control for direct lighting. This parameter controls the number of the rays traced from the shaded point toward the fire in order to find the optical passability between them. The number of rays cast towards the fire is the square of this value. If the value is zero, a special case is used and all emissive lights are sampled. This could be quite slow when having a big number of emissive lights.
