Failed to excute "texSubImage2D" problem with Three.TextureLoader

Questions

I loaded a texture by using Three.TextureLoader() and tried to render it by calling .texSubImage2D. But it emit the error below.

““Uncaught (in promise) TypeError: Failed to execute ‘texSubImage2D’ on ‘WebGLRenderingContext’: No function was found that matched the signature provided.””

I called the function like this

context.texSubImage2D(context.TEXTURE_2D, 0, 0, 0, context.RGBA, context.UNSIGNED_BYTE, loadedTexture);

Is the problem from CORS? or WebGL2?

texSubImage2D as a native WebGL function does not support an instance of THREE.Texture as its last argument (pixels).

Try it with loadedTexture.image. But you have to ensure that the texture is actually loaded otherwise its image property is undefined.

I already tried loadTexture.image before, at that time still same error showed.
But in this time it worked with “loadTexture.image” code…
I don’t know exact reason for problem, but anyway it solved.
Thanks!

ps.
In my case, TextureLoader.setCrossOrigin(“anonymous”) and
Asset source location does not affect to this problem.
