Description

When an OrthographicCamera is used, increasing the far value (> 3000000) will cause the perspective effect of the model. example: webgl_loader_gltf_avif.html

Reproduction steps

1.Create an OrthographicCamera 2.modify the far value: >3000000 3.load model

Code

let SCREEN_WIDTH = window.innerWidth;
let SCREEN_HEIGHT = window.innerHeight;
let aspect = SCREEN_WIDTH / SCREEN_HEIGHT;
const frustumSize = 600;
camera = new THREE.OrthographicCamera(0.5 * frustumSize * aspect / - 2, 0.5 * frustumSize * aspect / 2, frustumSize / 2, frustumSize / - 2, -100000, 1000000000);

@Jenychen1996 A live example is a fiddle, not a link to one of the official examples.

In any event, a negative near value is not supported by the library. So do not use -100000 but at least 0.

The artifacts you see are related to the lack of depth precision. In general, there should be no need for such large scaled view frustums so try to stick to a tighter one and scale the scene instead.
