Hi, I am getting some weird shadows when using meshes, I don’t think it is a bug, just me not using it properly. Facet next to each other are showing wrong shadows. Looking at the big cylinder, I would expect its surface to look much smoother. [image] I have tried to change the lights but the i…

Thanks for the help, unfortunately the format is proprietary. But I think i have found the issue, the issue is with my vertex and or the normals. The normals provided are not great, and even with computeVertexNormals(), the results is not very good, so maybe my facet vertices are in incorrect order…

Did you try flatShading on your model? I think this is more mesh related than light. mesh.material['flatShading] = true or for group of objs group.traverse( o => o.material['flatShading'] = true )

Unfortunately, flatShading did not change a single thing. Here is the material used for the mesh, in case that can help this.solidBodyMaterial = new THREE.MeshLambertMaterial({ side: THREE.DoubleSide, color: 0x5c6887, polygonOffset : true, polygonOffsetFactor : 1, polygonOffsetUnits : 1}…

How does you model look in a 3D Viewer like https://gltf-viewer.donmccurdy.com/ (Thats only for glTF) or in the THREEjs Editor https://threejs.org/editor/ What format do you have?
