Cloning a texture created with THREE.WebGLRenderTarget
Problem solved: I created a framebuffer texture, and I copied the texture by using method renderer.copyFramebufferToTexture() of class THREE.WebGLRenderer.

I'm using three.js and I need to create a few clones of a texture made with THREE.WebGLRenderTarget().
I can use the original texture, e.g.:
scene.background = renderTarget.texture;
But if I try to use a clone of it:
const tex = renderTarget.texture.clone();
scene.background = tex;
I get the following error:
THREE.WebGLState: TypeError: Failed to execute 'texSubImage2D' on 'WebGL2RenderingContext': Overload resolution failed.
If I add the line:
tex.isRenderTargetTexture = true;
Now I don't get any error, but the texture is all black.
I have also tried to clone the render target (instead of its texture) but it didn't work either. Can you please help me?
Thank you in advance.
