[Solved] How can I render a shader to a render target?

You don’t need to render from an orthographic camera. You don’t even need to setup your camera.

OK, but your code is missing the step where rendering is started without one, and a render target is assigned.

If the “cameraOrtho” from the Three.js instructions bellow could be eliminated by increasing efficiency without increasing complexity too much, then it could be a great alternative.

renderer.setRenderTarget(AATex);
renderer.render(sceneRT2TB, cameraOrtho);
