"Cracks" on a big skybox

Questions

Hi,

Here’s the video of the issue I’m experiencing Recordit: Record screencasts fast & free! with GIF Support! . Basically, with big skyboxes I see some kind of - I don’t even know how to call it - cracks. Here is the code:

const pathToEnvTexture = "https://www.babylonjs.com/Assets/environment.dds"
const envTexture = new CubeTexture(pathToEnvTexture, this.scene);
this.skybox = this.scene.createDefaultSkybox(
  envTexture,
  true,
  10000
);
this.skybox.infiniteDistance = false;

This seems to happen when I have a really big size of skybox around 10k.

I know it’s hard to help when you can’t get to see the full code but somehow I couldn’t reproduce it on sandbox. However, I’m hoping that someone will have an idea what might be the issue.

That looks like the maximum draw distance of the camera is too low. You can extend that by setting maxZ for your camera to a larger value:

Yeah that was it!

I wonder what are the costs of having maxZ distance set to a high number, maybe performance? (not sure what depth fighting issue is).

No perf issue. Mostly no impact unless you use very large numbers that will reduce your depth precision
