I want to build a mixed system that uses a non-threejs program to do some processing with textures that were rendered by threejs. To do that, I want to render to a `THREE.WebGLRenderTarget`, then later use the underlying texture in a non-threejs program. But I can’t find any way of extracting the `(gl.)WebGLTexture`. Can anyone help?

That’s reading pixels out of a buffer, but not getting access to the underlying texture. I would then have to copy the pixels back into another texture to use in my non-three program.

so you mean non-three-but-still-webgl program, okay, then inspect `renderer.properties.get( renderTarget )` and see if what you want is there
