Three JS Map Material causes WebGL Warning

Question

I\'m trying to define a material to meshes I loaded in from OBJLoader through the following wrapper function:

function applyTexture(src){
    var texture = n         


        

Answer 1

With WebGLRenderer, you can't switch from a material without a texture, to a material with a texture, after the mesh has been rendered once. This is because, without an initial texture, the geometry will not have the necessary baked-in WebGL UV buffers.

A work-around is to begin with a material having a simple white texture.

UPDATE: Alternatively, you can begin with a textureless material, and then set the following flags when a texture is added:

material.needsUpdate = true;
geometry.buffersNeedUpdate = true;
geometry.uvsNeedUpdate = true;

I also got this error while loading a scene from blender. For me the problem was fixed when unwrapping the uv's for each mesh i want to have a texture on.
