[Max] Resolved Bugs / 3dsmax adapter error: 3dsmax.exe process no response

« on: 2013-11-23, 06:33:27 »

At network render there very often render freezing by this error:"3dsmax adapter error: 3dsmax.exe process no response". I can't trace this bug by scene because it is in few different scenes and it happens occasionally. Has anyone this bug traced and may be this is no corona bug? (This scenes with Vray renders without any issues).

Attached files contains two scenes with no object inside. But this scenes generates errors in backburner with Corona. If I switch renderer to scanline all ok.

[Max] Resolved Feature Requests / CoronaMesh exporter/importer

« on: 2013-11-20, 08:05:58 »

I don't know is it right to request this feature here but anyway.

It is really freezing when you need to export a bunch of meshes in different files. With simple interface like in Vray it will be much more efficient. And possibility to import this CoronaMesh back to 3ds max as ediable mesh is needed too.

Gallery / Future flat animation with robots

My first try of Corona renderer.

There was some problems with flickering but with help of Rawalanche and other guys I've solved this problem. Those who interested in this are welcome to thread: http://forum.corona-renderer.com/index.php/topic,1974.0.html

[Max] Resolved Feature Requests / Path tracing samples per object/material

It will be great if it will be possible to definу a different number of samples to different objects or even materials. Sometimes we're waiting for removal of noise from only one object with noise and we need to increase samplews to whole image instead of just this object or material.

[Max] General Discussion / Animation flickering with HD cache

« on: 2013-11-15, 04:57:21 »

Hi guys.

I'm very interested in new to me Corona renderer. I'm doing a little clip of future interior with animated things like robots and furniture. Usually we're using V-Ray for our works but for this clip with lots of animation (usually we're have only people and cars moving in exterior scenes or just people in interiors). I found that Corona is great for animation and started to do animation with it.

During the previsualization I found a little strange thing with flickering the secondary GI named "HD cache" (it's not about the noise, but flickering of whole lighting of secondary GI). As you can see in attached file default settings (top video) of Corona flickering is quite pronounced. Of course I'm started to find the problem. And it was the parameter "Refl glossiness threshold". In default settings it has a value of 0.9. With this value it produces a cleaner image in blurry reflections, but in expense of flickering as I found. I don't know if it's right, but in my tests it is. Then I set "Refl glossiness threshold" to value 0.08 and render animation preview with it. As you can see at bottom video the flickering is much less pronounced in movie then with "Refl glossiness threshold" 0.9, but still there.

May be I'm doing something wrong and you know the way to turn this flickering down?

[Max] General Discussion / Render Elements

« on: 2013-11-14, 13:05:19 »

I'm new to Corona renderer, but exited it from first renders. Currently we working on animation and our beloved Vray unfortunately can't do what we need in acceptable rendertimes. We started to use corona renderer in this animation and was pleased by it. But we're faced with very strange render elements system in Corona. We need to have a Reflect and Refract render elements, but in Corona we're only had a ReflectGI element that does a different job as I'm see. Am I doing somthing wrong or it is really not the same Element as Reflection pass in other render engines? And with other elements the same story. I can't see many of standart elements, but it is a huge amount of unique elements to Corona.
