I have a character being rendered over a flat colour transparent background for use in an article of the same page colour. As the character has fur with alpha ends on the hairs, the background colour is important even though it is transparent, to prevent an antialiasing halo around the hairs.
I am using a gamma node to tweak the lighting. I notice this also affects the background colour, and I don’t want it to.
I can see the nodes have an alpha pass (good) and there is a colour input (RGBA) looking lik a colour picker but which unfortunately does not seem to allow me the luxury of choosing the colour by hex number.
…how do I wire the nodes so the background colour is the same as my original world colour, and not the gamma node corrected one?
