Infrared Filter Render

[Dippndots]

So this is a bit out there, but I was wondering if it were possible to add the ability to render out images in the infrared spectrum?

Interesting idea. I think this is rather a matter of clever post processing. So maybe some 3rd party app or a proper LUT could do this. I'll try googling around and report back if I find anything useful. :)

Yeah you can definitely fake it in photoshop, but it doesn't quite match a photo taken with an infrared filter, so I thought the same for a render. It seems like it would be better to convert at render time with all the source color info and lighting.

I do not mean faking. I mean using a filter and white balance, just like you do in real life.

It's not post-processing, just like polarization isn't :- ) I always wanted polarized renders, to globally tone speculars and get that nice rich blue sky ! Yeah you can override directly visible and reflection, but it's not the same, because this modifies the scene.

Basically, fakes aren't the real deal here. I've seen this request many times on Vray's forum without much answer.

Like Juraj pointed out, I don't think there's a way to do this without making the calculations at the source.

Of course it's possible, i'm doing that all the time :]

P.S. invert foliage diffuse and/or translucency maps and you'll get nice fake infrared render. Additionally you may also want to play with various luts.

How have you done the sky Romullus?

[romullus]

Google images->direct override :]

Edit: i've tried to plug Corona sky via color correct map, but didn't managed to achieve anything decent.

[Dippndots]

Ok, your method is definitely an option, but I think a built-in conversion would be the best solution. I know this shouldn't be a priority though, it's a pretty off the wall feature.

[romullus]

My method is just gimmick, it works only in very specific cases, but infrared rendering is very niche and i suspect its implementation is not a trivial thing. I highly doubt it will happens anytime soon, if ever.

yep, I can just move this to resolved, as there is almost zero chance this will ever be implemented (unless somebody is willing to finance this specific feature)

[Dippndots]

Lol, for sure Ondra, it just popped into my head yesterday on my way home, just thought it would be kinda neat.

[burnin]

For those interested, there's an engine that can do all that and then some... Ocean by Eclat Digital.

Whats the cost per feature :?
