Hi everyone! I’m creating a minecraft style voxel game and have hit a slight performance issue on the javascript side, with applyToMesh taking a long time. Currently I’m generating a chunk mesh on each block placement/removal which creates an entirely new mesh. Here’s a sketch of the code which do…

Hi @tyro and welcome to the forum. Any reason why you are using a custom mesh approach? Not knowing very much at all about minecraft I would have thought using individual blocks would allow you to mine easier? Babylon.js Playground FYI: Minecraft classic ( classic.minecraft.net ) uses Babylon.js

Hi @JohnK , Thanks for the reply. Minecraft style engines typically render the entire chunk (16x256x16 blocks for Minecraft) as a single mesh as this significantly reduces the render time. The trade-off (as you state) is that adding/removing blocks is slower computationally, however it’s a trade of…

OK I understand. It might be worth looking to see how the Minecraft classic engine optimizes and then renders with Babylon.js. Hopefully other might have better advice.

Noa engine is based on Babylon.js :slight_smile:

I think the SolidParticleSystem might be the answer to your troubles, in combination with some smart algorithms to re-use & only render visible boxes. // 10k boxes https://playground.babylonjs.com/#LXXL6Y#22 // SPS docs https://doc.babylonjs.com/how_to/solid_particles By re-use i mean that yo…

Hi @aWeirdo , Thanks for the reply! I don’t think SPS is a good fit for me here as it only uses one material and doesn’t seem (?) to support shader attributes which I would need to apply on a per block face basis (for flood fill lighting ). However, I will check out the SPS source to see if it has a…

@tyro may also benefit by looking at the code for open source Minecraft-inspired games like Minetest. It is definitely a cool idea. I am hoping to do something similar with BabylonJS after I advance my coding skills a little more.
