I’d like to pass a map options that holds a texture to my custom ShaderMaterial but I get an error, like this: const material = new ShaderMaterial({ // ... literally copied MeshLambertMaterial shader here, verbatim ... map: texture, // and I want to use a texture }) // ... renderer.render(sc…

Here seems to be someone with possibly the exact same problem, but no solution yet: https://stackoverflow.com/questions/34542508/custom-shadermaterial-map-issue

Ah, seems all I had to add was: material.map = texture and it works! So, const material = new ShaderMaterial({ // ... literally copied MeshLambertMaterial shader here, verbatim ... map: texture, // and I want to use a texture }) material.uniforms.map.value = texture material.map = texture …

This worked. Thanks. Although the console yells at me =] THREE.ShaderMaterial: 'map' is not a property of this material.

Ahh!!! It worked for me as well. Cheers!! [image] [Solved] Recreating build-in materials using ShaderMaterial Questions Hi Everyone. I have been trying to recreate an existing MeshPhysicalMaterial using ShaderMaterial. The base code is extracted from the ShaderChunk wher…

I’m super confused as to how this works. const material = new ShaderMaterial({ map: texture, //this should cause absolutely nothing to happen }) This should cause nothing: mrdoob/three.js/blob/dev/src/materials/Material.js#L106 } …

Turns out the only things that are necessary are setting uniforms.map and defines.USE_MAP. material.map does nothing except cause a console warning. This should be better documented imo. One has to search forums / SO to find the answer to what I would imagine to be a somewhat common use case.

Well the only way to do that is to voice some opinions on github. You’ve been part of some discussions but excused yourself eventually. This way there wont be much improvement :cry:

I just read a 3 year backlog of NodeMaterial and related conversations. I see now why there was pushback on altering materials, seems like the future is not settled, and changes are therefor discouraged it seems. [image] pailhead: Well the only way to do that is to voice some opinions on github…

What do you think needs to be added here? https://threejs.org/docs/index.html#api/materials/Material.defines Or here? https://www.khronos.org/opengl/wiki/Core_Language_(GLSL)#Preprocessor_directives
