Title: Shadow Density
Post by: darrentomkins on 2016-05-31, 22:15:55
Stupid one...

In max it's easy to adjust your shadow density and make it darker or lighter but where in Corona do you achieve that?

There's no equivalent setting, as this would be a non-physical approach (Corona works out how much light is hitting the surface based on physical laws). I'd say for this you'd go with adjusting Exposure, Contrast and similar in the VFB (or in post), or adjusting the lighting set-up to stop so much light getting into the shadows. Depending on what the scene is, you might add an AO pass to "fake" things. Hope this helps!

Hi,
try the latest daily build - it comes with experimental Filmic mapping, which has a "shadow richness" parameter

Magnificent, where do I download it and will it affect my license?

I tried the new Filmic highlights. But, in my opinion, it ruins the image. It compress only the very bight area of the image. And the rest of the rendering will remain the same.
With Highlight compress, the entire image is compressed and the result is more uniform, better quality of the lights.
Maybe I didn't understand how to use it =)

Filmic shadow is a little bit more interesting and it makes the rendering more contrasted.  It's similar to the "S curve" in Photoshop.

Correct, but also loses saturation as a result. Filmic was made to adress the problem of either having desaturated colors or too many uncompressed highlights.
Some devs from uncharted made a presentation about it (http://www.slideshare.net/ozlael/hable-john-uncharted2-hdr-lighting), slide 53 onward is your friend.

But I don't like it either :D
