[REQ] Colorcorrection Shader

Post by Behrendt » Tue Oct 27, 2015 12:18 am

Hi guys,

as discussed in the Cindigo Forum I think it would be very handy if there was a colorcorrection Shader inside Indigo. In C4D there's a shader that offers possibilites to change Hue, Saturation, Brightness, Gamma, Low & High Clip, etc. If Indigo could provide these options directly an easy accessible I think this would be a really great thing as it definitely would increase working speed and ease of handling textures.

Kind regards

Christian

I'm very much looking forward a modular edition feature for Indigo, grab-connect-tweak wise. Though I recon that I'd tell "it's an exporter thing" right now.

Hi

The view of the rendering engines is a very crowded market (Indigo, Maxwell, Corona, MentalRay, Iray, Arnold, RenderMan etc.) and are required in addition to the financial capacity of the developer.
Glare Tech. is a small company of a few developers (3 or 4?) and we can not expect the impossible; there are priorities.

I'm fully aware that the Indigo team is quite small. Nonetheless I think that this shader might be implemented quite fast, in comparison to other requests. Also I think that usability is quite important for Indigo in order to develop and grow in the future, as usability is quite a big factor when it comes to rendering, especially in production. I love Indigos quality, but as a Freelancer I can't see it becoming my production renderer anytime soon, and this isn't due to speed issues, but mainly usability, as a lot of things are still quite tricky to achieve or need lots of workarounds, which proves difficult on deadlines. So I think every little improvement in terms of usability will ultimately benefit Indigo a lot. ;)

This. Ono did mention new postproduction tools are planned, maybe the same principles could be used to manipulate textures as well?

We'll add this to the todo list. Actually it has been quite heavily requested for a while, so we'll try and make it happen in not too long. Technically it's not very difficult, I think. As usual most of the work will be exporter and UI support.

Yes please!
Also with a function to adjust input level of textures via ISL, so the albedo color doesn't get over 204.
Its a real pain to modify every albedo texture in a scene to be in the 204 RGB spectrum!

Setting b to 0.8 won't do the trick?

IHMO it depends of gamma setting, you will need .91 with gamma 2.2 to get .8 reflectance.

I've set a simple scene, one cube has only colour another has a white colour image, then tweaked such as they would both present the same colour strength in render, I had to lower from 0.8 which I used to use to 0.61 to get equivalence.
I've been living a lie! :O
