You have an old version of Corona with incompatible parameter names. There are versions of the script earlier in this thread that work with the older version.

I'm sorry for this temporary incompatibility, soon there will be Alpha v3 as the main build, where the latest version will work

It would flicker, so I would not recommend it for now. But you can try ;)

and I believe the correct term is "Coronaut" :D

Off-Topic / Your OTHER renderer?

« on: 2012-09-17, 23:01:52 »

I'm just wondering, what is/was your main renderer besides Corona ;)

Hi and welcome,
other 3D software support is definitely planned, but not for the near future. The plan is that it will be done by different developer, because it is quite separated problem, and I dont want to experience another horrible API ;). And I need to get the money for that developer first ;). So you'll have to wait at least a year.

thats great suggestion (moving it to GI rollout), I've already done it ;)

I think Rawalanche means diffuse reflections

Its only for GI; its not needed for direct light. Just set it to some reasonable value to balance the bias/variance ratio ;).

About the direct/indirect: GI rays can randomly hit lights. But because Corona uses MIS, such cases are properly weighted, and do not cause any fireflies or bias. They, in fact, increase the robustness when using large area light sources and when sampling very close lights. When using MIS the distinction between direct lighting/GI partially vanishes.

I am really sure that the fireflies are not from hitting lights directly, because Multiple Importance Sampling automatically accounts for that (unless you have lights sampling set to something other than MIS).

Also, you cannot exclude lights from GI calculation, GI is induced solely by direct lighting, you wouldnt have any GI without the lights.

So, the possible reasons for fireflies are either
- caustics (light behind some solid glass/mirror)
- bright spots (light very close to some geometry)
- general inefficiency of path tracing in interior scenes

First two causes can be easily fixed at the cost of some small bias by setting "max sample intensity" to about 5-10. The last is intristic deficiency of path tracing, I would recommend switching to PT+HD in that case.

Anyways, it would be much better, if you could post renders and screenshot of your render settings ;)

The features are implemented, now it just needs some testing and documenting

right. I've fixed it. I can give you the build on skype, dropbox not working for me ATM.

ok, thanks, same goes for other converters (if they use any parameters)

I've renamed the parameters in the newest build, so the script is temporarily broken, until somebody rewrites it.

[Max] Feature Requests / 1 feature request per thread!

« on: 2012-09-15, 23:55:17 »

Hi,
to reduce the mess in this section, I've decided that each feature request should have its own thread (with meaningful title), so it can be followed, discussed, and resolved separately.

There is Reflection GI pass, which does not include a portion of direct lighting. I am reluctant about making full reflection pass now, because it would inevitably lead to an overhead :/. But I know it will be necessary to add in future

Can you give and example (image or scene) of such situation? Is it when using PT+PT, or PT+HD?
