Hi
Just a brief note to say that some of the scenes shared in this section of CGTalk are used elsewhere by render engine makers and on rendering papers without crediting authors, which is not in the spirit of this community or the people who shared their scenes.
Thanks for the message, can you send me a pm where you’ve found the scene used ?

Links checked. LC#47 links now are on. Pls if you find any broken link let me know

I would like to create a “repository” of ideas for lighting challenges. Please focus both on the technical and artistic aspect. Just to start the thread
@jojo1975
I believe nowadays the difficulty of rendering a Photorealistic scene is much easier than how it would have been 5 or 10 years back.
realtime renders soon will catch up with offline renders.
so I think we need to focus more on what makes a Photorealistic image believable. rather than how lights are bouncing around and how the light approximation is done.
for example, most of the modern render engine is capable of rendering whatever you throw at them .lights are bouncing, scattering through the surface etc!
but still, we can end up with the bad looking shot I don’t think any rendering advancement can fix that.
There is a secret sauce in making a believable image but I don’t think that’s the render engine capability they (Pixar, ILM, etc) have compared to the others.
The photorealistic scenes are not difficult to render(render time, how light behave and stuff) but what difficult is to achieve the believability in those images.
so yeah basically I think we have to learn how to produce a believable image and let the AI do the rendering and denoise 
Hello, we have not seen a new challenge for a while. Looking forward for some comments.
We are organizing new challenges. Hopefully we will back soon. I need also to clean the forum a bit 
Hello to all,
so I’m gathering a few ideas for the next challenge !. From now on the pace of the challenge will be more “scheduled” with a challenge every 3 months, a better final gallery and hopefully other news 
So the themes that comes up to my mind are
— Your ideas…
Also… since I want to revamp some scene… and to create a redux challenge (like the one for the bottles) what’s your favorite challenge since now ?
G.
I would be up for either the scifie corridor or the real-time still. Both are great ideas.
IMHO, reviewing the purpose of this forum/sub-forum should probably be the first step before the next challenge.
If the goal is to simply improve one’s lighting and composition (aka cinematic) skills, then it may be helpful to obtain scenes that are “ready-to-render” - i.e. add lighting only.
If the goal is to develop one’s skills as a Lighting TD, then the current challenges meet this requirement. Most of the assets in all of the existing challenges (1 - 44) require a significant amount of cleanup and texturing before they can be adequately lit.
BTW, this discussion should probably move to:

cheers,
10 years ago things were very different and now the quality has improved a lot, even if small challenges still seems to still work best . I’m thinking about still life without involving too much textures were it’s easier to include procedurals shaders and also when you don’t need to work too much on textures uv unwrap and other stuff.
Generally we had donations for the models so it was an obj that people started working on and share with others
I’m in the effort of cleaning the old scenes to create a better repository and also cleaning and creating galleries for the last challenges we need voluntaries and modellers. can someone help ? Send me a PM
Also the next challenge will be HUGE with pro models,textures like it was never seen. I promise. In the meantime let’s do spring cleaning

For what it’s worth, I really like the challenges which are rougher - requiring shading and texturing and maybe even some additional modeling … they allow everyone to go their own direction at a more rudimentary level … and personally they help me learn a lot more.
I am wanting to go back and work through the challenges until I’ve done them all, these are great
I know it’s hard to pull off in multiple formats, but an animated shot for lighting would be a lot of fun …
This is crazy…
I was browsing forums, and saw this:

I’ve read it like “lightning challenge… elizabeth… batorry… pool”
So, here’s the idea:
Elizabeth Batory pool of virgin blood (by myth).

It’s gross, but it can be cool lightning challenge.
