I can never get this to work in Corona and I usually have to fudge it.
I'm projecting a backplate onto geometry (a terrain model), and also using it as my background (for the sky) and I want the projection to render exactly as it appears in the backplate image file.
I'm using exposure, tonemapping, and a LUT in the frame buffer.
I'm using the tonemap control node and I've disabled all buttons which I thought should leave the backplate in tact but if I adjust the framebuffer exposure, or toggle the LUT (Kim Amland Photographic), the backplate changes and it always looks weird.
Am I missunderstanding the tonemap control node? Any suggestions? Thanks
