Some Graphical Effects Gone/Not Yet Implemented?

[Anon]

I remember that the there used to be options in the track exporter for cloud shadows and colour correction, and that there was some talk of having height dependent fog in the new engine. Are these features that I can use, or are they not in the engine at this moment?

Fog height is trivial to implement but I think the exporter parameters names are confusing.
Cloud shadows also need some parameters (cloud texture, movement...)

color correction is unavailable at the moment.

Okay, cool. Are these parameters documented anywhere?

Hi

Fog height should be definitely implemented. I will check if the exporter doesn't support the parameter I will add the option.
Cloud shadows not sure if it's still present. It was done by cand during the GSoC project, but I think now it's not working with the new engine.

Color correction was done but it wasn't a "real" color correction. I'm planning to add the full color correction (color grading, contrast, light, sepia, black and white + all sort of stuff but the way it will work will be different compared to how it was working previously. The shader itself isn't difficult but it might be done after the beta

Actually fog height will be much more challenging that I initially thought since it involves solving some integral (density won't be uniform anymore). It probably has an analytical expression but I'm a bit lazy to do all the maths...
There is an algorithm that use discrete approximation but it'll take some time to implement properly.

Cloud shadows is still doable however.

Maybe fog should just float around on its own?
