Hi all! My question is pretty short. I would like to achieve this kind of lighting in my scene. Reference image is from Star Trekish ship :slight_smile: [0cf3a7e2afe46d1a98f64720967ca858] As you can see, the light in that picture comes from bottom and top lights that are not exact points. The ot…

A Lot of Lights demo - Babylon.js Playground

You have to be very creative with very few “real” light sources… The scene in question I wonder if you could make the lights simple holes in the geometry and surround the whole thing with a lightbox maybe?

Thread resurrection commence :slight_smile: I’ve been doing some other things related to lighting. I have however determined to use one of the following solutions: Use the “lots of lights” demo as a base and try to dynamically turn of lighting when player cannot see them, and also use the includ…

Are there some limitations with the lights and their includedOnlyMeshes property? I made a test to light the instance (sphere) with point light using includedOnlyMeshes after two seconds and nothing happens. See: https://playground.babylonjs.com/#1FUKMR#4 If the original sphere is used, everything…

Hmmm, I see! But is it possible to not do this in the same tick? In my real project, I would like to create lights dynamically when I create the map from mesh pieces… So the scene has already been initialized, I just add stuff into it :grinning_face_with_smiling_eyes:

Anyone having an idea why the instanced sphere doesn’t update in https://playground.babylonjs.com/#1FUKMR#4 when created in setTimeout? Does this have to do with the picture I posted before, as in instanced meshes lights are coded in a way they do not update the lights afterwards? :slight_smile: Al…

[tenor] Hi everyone! I’ve been theorycrafting my use case a lot during these few months but I need some help to validate the “solution” I’m thinking of doing. So, I’m thinking of creating two versions of the texture, the “lights on” and “lights off” versions for each wall/floor mesh. Then, I woul…

sounds like it could work but maybe @PatrickRyan would have some tricks to fake it ?
