I want to use the draw edges method from How to render geometry edges? - Questions - three.js forum (threejs.org) but I also need to support AmbientLight, DirectionalLight, PointLight and SpotLight. How can I mix these shaders?

Hi! What result do you want to achieve? Any explanatory or reference pic?

[image] This cube has the StandardMaterial because it needs to be flat shaded, the cube is white and the scene have a directional light. [image] This is the same cube with ambient light instead of directional. I’d like both have the edges visible.

For some ideas, have a look at this post: Detecting objects which can camera see - #10 by prisoner849 MeshBasicMaterial + .onBeforeCompile

The shader of here doesn’t work because of some of my cubes are scaled. The problem of MeshBasicMaterial + .onBeforeCompile is that I use both MeshBasicMaterial and MeshStandardMaterial in other places that I don’t want to show the edges.

[image] TiagoCavalcanteTrindade: The shader of here doesn’t work because of some of my cubes are scaled. Do you use instancing? [image] TiagoCavalcanteTrindade: I don’t want to show the edges You can use a uniform, for example, a boolean one, for enable/disable box’s edges :thinking:

Do you use instancing? Yes. You can use a uniform, for example, a boolean one, for enable/disable box’s edges :thinking: I guess this would solve, I gonna check it now.

I tried the following, but it didn’t work: new MeshStandardMaterial({ color: new Color().getHex(), flatShading: true, defines: { MY_EDGES: true }, onBeforeCompile: (shader) => { shader.vertexShader = ` attribute vec3 instData; ${shader.vertexShader} `.replace( `#include <begin_ve…

I meant a uniform, not a define.

I meant a uniform, not a define. Oh, my mistake. With uniforms it is having a strange behavior. new MeshStandardMaterial({ color: 0xffffff, flatShading: true, onBeforeCompile: (shader) => { shader.uniforms.edges = { value: true }; shader.vertexShader = ` uniform bool edges; attrib…

Oh, wait, I thought you want to implement that approach for edges: How to render geometry edges? - #7 by prisoner849
