PixelPush Posted November 1, 2017 Share Posted November 1, 2017 Having a play with volumetric lighting scattering post process. I'm trying to achieve a beam of light, like that from a torch or spot light. So far I've only managed to get points of light to emit from the mesh in a radial/global pattern. Is it possible to control how the rays are emitted from the mesh and/or light Ta Quote Link to comment Share on other sites More sharing options...
Wingnut Posted November 2, 2017 Share Posted November 2, 2017 Hiya PixelPush! Sorry for the slow replies. By design-necessity, the godrays (VLS) system is a post-process effect, which means it is sort-of "down-stream" from 3D land. It is done during the view rendering. It is a 2D thing. https://www.babylonjs-playground.com/#HYFQJ#23 (Wingnut doesn't talk 'tech' very well.) I once tried some real 3D cones on some spotlights... with a little smoke/fog as a texture on the cones, and some alpha (transparency). It's okay, I guess. Fake VLS. You can adjust cone transparency in lines 204, 212, 220, 228. http://playground.babylonjs.com/#2IGNZ2#3 Generally speaking, real-life lights don't show their "volume" until a bit of fog, smoke, rain, snow, or dust blows-through the beam. Others may have better comments and examples. Stay tuned. Pryme8 and Dad72 2 Quote Link to comment Share on other sites More sharing options...
