Having the ability to bake multiple occlusion passes in the baker, along with the directional bias feature, would be very powerful. We could create effects like leaking by using bias and spread. In the gif below, I demonstrate biasing towards the y-axis downwards, playing with spread, and adding noise/texture to it.
Some rendering engines have this feature, but I haven’t seen it in any texturing app yet. I would love to have this ability in instamat.
