@julien-moreau how would you recommend doing some fast volumetric fog with 6 point lights interacting? Should I just follow along with: Volumetric lights - Alexandre Pestana and do a loop for each light? I tired with the Use the Volumetric LightScattering post-process - Babylon.js Documentation …

@Pryme8 , an unconventional approach, from the falcon - as usual. Put a box of frosted glass around the camera? GREAT random refractions in transluscent 2D Plane experiments recently. Next, attempt is to BOX THE CAMERA… like 2D filters. Just in 3D. A static box around a cam. It is imprecise. Bu…

why you challenge me :slight_smile:

@aFalcon Ive had a raymarch solution for a while its just not done yet. https://www.babylonjs-playground.com/#1UWAVK#28 I have not been able to get a raymarched solution working in the manor that I want, I was close at one point I just cant get the “slices” to line up correct and have been strug…

[image] nasimiasl: challenge me Calling batman (for a friend). : ) Nas starts the concept of “challenges”. So, it is for your joy. CONCEPTS: for general fog Do you have a good fog already? Better than Falcons unconventional CAMBOX (no doubt). @Pryme8 - that RAYMARCH PG is AWESOME (wish I…

[image] aFalcon: Also I learn RayMarching from you. Awwww, dude I did not know :slight_smile: that kinda makes me happy. I might not be the guy to teach you really, but I am glad that I could introduce you to something so interesting. If you have any questions or confusion on things let me …

Got it! The effect works. Your RayMarch GREAT starting point. Put the CAM in a BOX, invert the culling, drop the alpha, BLEND more, and ANM UV. Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes This code is reall…

Check this out out too, I forgot I added uniforms controls https://www.babylonjs-playground.com/#1UWAVK#25 You should be able to go “inside” of this box as well. I also need to get some script in there to pull it out of a death spiral of steps and do a more loose approximation so when you are all…

@Pryme8 Unfortunately it is now intended to work with multiple lights at the moment :frowning: Also, it works only with spot light. I recommande, for point lights, to adopt a ray marching method but the problem stays the same: you’ll need 6 shadow maps per light and compute Ray marching for each.…

I might be able to make that work. <3 Its not really want I want but its the best for client considerations.
