My scene setup uses an HDRI for the horizon, sky and lighting.
I want to render out PNG’s with a transparent sky, but the horison for the HDRI.
I’ve made a PNG version of the HDRI with an alpha layer, with a transparent sky, and set up this nodetree for the environment material:
but the alpha of the texture is not coming through.
Now, I COULD create a second sky texture which is just the alpha layer, and use the sky texture to mix between transparant and the scene… but… I’d need to have two different sky texures in the scene, and I can’t find anything in the render layer settings that allows me to giver a layer a different sky texture.
