Hello, I’ve been trying to add shadows to my huge terrain. I’ve been thinking it would be best to add the shadow to the camera so while to camera moves around the shadows are only rendered for whats within the view of the camera. Here is my attempt: let root = new THREE.Group(); root.add(camera);…

It seems you have not yet configured the frustum of the shadow camera correctly. Try it like mentioned here: [image] Shadows: incorrect shape and transparency ignored Questions Your shadows is clipped since the default frustum of the directional shadow camera is too small…

I tried adding this: const d = 100; light.shadow.camera.left = - d; light.shadow.camera.right = d; light.shadow.camera.top = d; light.shadow.camera.bottom = - d; And got this: [image] Looks bigger but unfortunately still no shadows.

Are you sure that materials of your model are not THREE.MeshBasicMaterial()?

Yes, all are THREE.MeshLambertMaterial. Just to be thorough, I also added mesh.receiveShadow = true; mesh.castShadow = true to everything in the scene. And made the frustum const d = 1000; to be huge but still nothing: [image]

Is your city one big object? Or does it consist out of many single meshes? Is it possible for you to demonstrate the issue with an editable fiddle ? BTW: Don’t forget to globally enable shadow maps like so: renderer.shadowMap.enabled = true;

Yep, I also did that. Including setting the type of shadows to soft. The terrain consist of 1 big mesh, with about 225k vertices and about 500k+ faces. I know I should optimize this in someway but that would be another question as I have no idea. But for now, I’m having issues with shadows. Unfortu…

Please try to switch to MeshPhongMaterial to see if it helps. Shadow quality with MeshLambertMaterial is poor in any case. It’s not a good choice for rendering shadows. Besides, there seems to be something wrong with the normal data of your geometries. When I set the intensity of the ambient light …

Should I just let THREE.JS calculate the normals? Instead of adding them from my assets? I tried changing all materials from lambert to phong. Removed the ambient light. Tried fixing the normals to no success. And I got this: [image] I’m starting to see shadows but I guess the normals issue is c…

With such a large frustum, shadow quality will be bad in any event. Try to keep the frustum as small as possible and also alter the angle of the light a bit (so it does not cast shadow from top).

I have the same issue… Trying to cast shadows on a loaded FBX with material MeshStandardMaterial. Works totally fine for point light. Nothing with directional light. :frowning: plight shadow works fine: this.plight = new THREE.PointLight( 0xffe673, this.env.plight_intensity,60 ); this.plight.…
