Need helps to tell the methods of features in LG smart Home

All lighting baked in this scene only some of object (mostly main) works with environment, but I don’t think this scene has even a one point light.

From my experiences…eliminate light sources. Bake as much as you can. Simplify your geometry to the extreme using textures to give you details…dont model them. Minimize textures draw calls by using multiple texture atlas files. This particular scene is very simple. You can look at the code, calls and files using the Googles Developer console window…because this stuff is stored local you can gather it all up and review it all yourself locally to see how they did it.

There are some good guides in the Verge3d manual under performance enhancments that will help you get there. In this LG example, they put performance above quality…which is why it looks so bad / heavily compressed. They use the same objects and probably cloning use the same colors and textures for multiple objects…typical gaming tricks.

But overall it’s super lightweight…which is why it performs so quickly. It’s up to you as the artists/producer to weigh the balance between speed and quality. It’s a fine line to get the balance right. Whoever put this together went all-in on performance. This is because the LG products are pretty much all rectangular and are just mapped…so didn’t need detail in other things. So bake, bake, bake to JPG and compress the hell out of the JPG and you should get similar results if your gltf is small.
