The progressive adaptivity that has recently been removed was pretty usable.  You could set gi samples to 2 and then most pixels would get only 2 samples and those above the given threshold would get 2*x samples after y passes. It worked pretty well, not sure why Keymaster removed it. I hope because he's preparing an even better version. :)

That's because you are using caustics. When you enable them, refractive objects cast shadows and then caustics are computed. Caustics are a bit painful for Corona right now so I would suggest turning them off, at least for the drop objects. Do you really need them? Caustics on glass?

Nice! I can see you've made huge improvement since your first posts. The cow model is really cool. :)

The third shot is definitely the best.
What I don't like about the others is that they consist of 3d and 2d elements poorly mixed together (white borders around bitmaps, etc). In the river shot, you can also clearly see that the scale is wrong. There are some small bushes/grass at the river bank so the house must be tiny. :)

It depends on what level of detail you need but I think it looks ok in your tests.

Well... it simulates light scattering through some media so you can use it for SSS, smoke and volumetric fog effects. This could add to the "mystic after-rain feeling" but it's still in development and available only in daily builds. :)

Great, clean renders. I am no expert but the architecture also looks appealing to me - simple and functional.

I think debris maker was also involved. :)

I wonder if these works would benefit from use of new scattering media feature.

If only there was a way to map translucency fraction as well.

I thought there is in A7. No? Then it must be in newer versions so you can expect it in next public release.

Here are my tries. Ugly scene, one-sided translucent planes with bump map (gradient ramp). I think it works pretty well. There is also a second version with glossy refraction but it renders slightly slower (see file names).

Oh. Sorry. There should be some official topic with the rules available to everyone. I would post the text from that thread but I don't know if it's ok to do so. Anyone?

Why don't you try with translucency? In the reference pictures you posted, the effect looks like it could be achieved with translucency or with glossy refraction if you really need to be able to see what's behind the panels.

Thanks to advanced search functions, forum category knowledge and some l337 hacking, I am providing you the link with answer to your question:

Are you using DOF inside Corona?

I can see you have a dark "interior" here with lots of glossy surfaces and strong DOF.

I would start with something like this, these are just suggestions:
-disable secondary solver (set to none) - as you have virtually no visible GI bounces (or maybe?)
-GI/AA = 8
-LSM 1 or less if this won't cause more noise (maybe 0,5)
-you can try lowering MSI and ray depth if it brings some performance improvement

And use progressive, not buckets.

Guys, what the hell? It's just a re-creation of a historic building. Would you say the same about a WW2 aeroplane with swastikas on its wings? "Bad idea"? :D

« on: 2014-08-15, 18:35:57 »

I'm not an expert either, but I think the kind of color mapping applied in Corona is dependent from the output format and it usually is called sRGB and the thing you wrote about is post processing done in some other app (like photoshop).
