[Capture.PNG] Materials : PBR based MeshStandardMaterial. Lights used : hemisphier light, ambientLight, DirectionalLight Directional light is used to display the shadow. Direction light’s position set to (0, 200, 50) and bias is set to -0.002 Problem: Some angles, black lines are visible on pr…

If I turn of castshadow and recieveshadow, I still see the lines. I think that is caused by a texture in your model. If I change your material by replacing it with a MeshNormalMaterial, then I no longer see the lines. for (let i = 0; i < childrens.length; i++) { childrens[i].castShadow = true;…

@seanwasere i have to use MeshStandardMaterial along with PBR flow, so would please try with MeshStandardMaterial only ?

same thing, your problem is not shadow even if I turn off shadows in your renderer, it still see the lines renderer = new THREE.WebGLRenderer({antialias: true}); renderer.setPixelRatio(window.devicePixelRatio); renderer.setSize(window.innerWidth, window.innerHeight); renderer.outputEncoding = THRE…

Let me check the other model and give you the exact issue

Tightening up the shadow frustum and descreasing the bias a bit fixes it: dirLight.shadow.camera.top = 170; dirLight.shadow.camera.bottom = -70; dirLight.shadow.camera.left = -150; dirLight.shadow.camera.right = 150; dirLight.shadow.camera.near = 25; dirLight.sha…

I concede, there is a shadow problem if you look really closely. This is usually solved by tweaking the bias. Left, shadows enabled in renderer Right, no shadows enabled in renderer [image]

Can you try it with my updated fiddle? I can’t see any artifacts. [both]

[image] looeee: dirLight.shadow.bias = -0.005; its a solution, tanks

I have found solution in docs. three.js docs Very tiny adjustments here (in the order of 0.0001 ) may help reduce artifacts in shadows

Oh no, I just changed the sliders and I broke it. This is a best as I can milk it with those pesky sliders.
