The A show (post your Thea images)

Hi Adam,

I don't think there's a public relight tutorial, only an internal video, which needs to get updated...

I've never used the relight option myself, but I know that Pete master it...
Here's what he wrote some time ago...

Save the scene .scn.thea and then save the image as .img.thea

Now you can either continue the render or just load the completed image for relight adjusting and saving etc by reloading them.

Please also see page 26 in the "Manual.pdf", which can be found in the directory, where Thea is installed...
(I.e. C:\Program Files\Thea Render\Manual.pdf)

Adam

Do you have a scene you want to use relight with?
Please feel free to ask any questions and I will try help where I can.

If I get some time I will compile a simple scene and set up for relight then make it available as either a test scene or tutorial (time being the decider)

Alternatively if you have Skype then I could walk you through a basic setup.

Would it be possible to video the Skype session?

i think the best part of relight is that you can play while the render is happening. its freakin awesome! pretty well worth the price of admission for that alone.

Okay, I'll stick my neck out and possibly look like a fool - could someone explain what relighting is? I read the manual but I don't quite get it - and I've had my third cup of coffee already so I can't blame my incomprehension on lack of caffeine.

Thanks.

check solo's video on the first page of this thread and drool. in short its the ability to adjust individual lights in the scene after or during render! in a lifetime it could save years of rendering;re-rendering;re-rendering...

Its basically a feature that allows you to control the intensity of light sources in the scene after youve finished rendering. As an example, imagine you have a room lit from a window and 2 intreior lights, using relight you could do one daytime image with the scene lit entirely from the window and then a night image lit entirely by the interior lighting, and you get all that from a single render.

There is a small relight example scene in Thea Render installation dir ".\Thea Render\Scenes\RelightExample". At Scenes dir you will find some other sample scenes in Thea format (note. there is a outdated glass-liquid interfacing scene too, don't bother with it, but get this scene by harford).

Got it! Thanks.
Now we need a good tutorial ...

EarthMover · 18 Apr 2010, 22:14

Thanks everyone. Looking forward a rundown on how to setup for Relight. Pete, I sent you a link (PM) to download my scene if you get a chance. If not, no big deal.

I've been using Maxwell's Multilight feature for years which is obviously very similar to the Thea Relight system and even use it for exteriors where no emitters are in scene, I just create an emitter and place it beyond the scene where it will have no effect, you can though still set it's power to nil or disable once processing (to enable ML one needs an emitter other than just the sun). This allows me to play with both camera and sun power to get the best lighting / shadows results!

SO I'd suggest this may be something worth testing even for the most simple exterior scenes, and trust you will likely never render again without this feature enabled!

its pretty simple, turn it on in render settings and you get a slider and a color picker for each light. play away!
(might not actually be that simple but it was for me ;~) )
