Excellent work, indeed!

Confirming that arbitrary cut planes are not supported by the Corona core - it's only coming up in corona 4 (version under development).
Maybe Jan has implemented some workaround or temporary solution.

this discussion belongs to 'general'. Please use this channnel only for feature requests. Thanks!

please put feature requests in the relevant section. macOS port feature request has already been recorded. Will be done.

we'd love to take that feedback. But - could you please, for each change, explain why you need it, what it would be useful for? This way, we'll be able to make a better informed decision. Thanks!

Denoising coming up in today's daily build ;-)


all of it - there's testing of the tech and also contracts to write...

But more, I was just curious to know what farms people like in general.

Beautiful, thanks much for sharing!


Any input on this? Do you know of any important farms that still do not support Corona?

Hi C4D-Coronauts,

as a part of our effort to make the integration of Corona into C4D really smooth, we want to ensure good integration with some of the major render farms.  We're planning to start off with some three farms and then potentially add more pending popular demand.
So which ones should we start off with? Just list the three best ones for Win and OS X.  Thanks!

Yup, same timeframe - 2nd half of 2016

Hair planned for 2nd half of 2016.
The shader will be some kind of Marschner model (all today's hair shaders are some variants of that).
I think we'll start off with alshaders hair.

Hey guys,

I'm in charge of research in Corona so I took a thorough look at the paper. I came to the conclusion that it is not very useful for Corona at this point, for the following reasons.

First there is the overhead: for some rough refractive surfaces, the render time can get almost twice longer with the method in the paper - definitely not something we would want to see in Corona.

Second, what does the paper really has to offer in exchange for this overhead? In fact, nothing that Corona wouldn't already have.
What they use is the usual microfacet BRDF (such as GGX) but they can ensure that energy is preserved as the roughness/glossiness changes. In other words, the material does not get darker/brighter as you tweak glossiness.
But we already have a different solution for exactly the same problem in Corona which works just fine. Try to play around with CoronaMtl and you should be able to see that there is actually no darkening as you change the reflection glossiness.
Current version of Corona still has some issues with energy preservation of rough *refraction*, but we already have implemented a solution that works very well and we will release it in a daily build soon after 1.4.

So there's probably not much to get out of this paper for Corona.

Will look into this at some point.

[C4D] General Discussion / Re: C4D Seam Issues with SSS
« on: 2016-02-26, 16:20:26 »
not sure yet if this is a Corona issue. In fact, I'm a bit confused by the description, so I'll ask some simple yes/no questions:

* Does the seam appear in Corona with SSS on?
* Does the seam go away as you turn SSS off (still in Corona)?
* Does the seam appear in Keyshot / Arnold Render / Blender / Vray with SSS on?
* Does the seam go away in Keyshot / Arnold Render / Blender / Vray as you turn SSS off?

Can you please post pictures?  The scene itself?
