Too many polygons is not a problem for CentiLeo ) It can eat any counts. You may see an example of our out-of-core technology https://centileo.com/news/147/centileo-out-of-core/
Btw what's you system CPU RAM size?

A lot of metalls can be nicelly implemented with 2 or even more reflection layers stacked on top of each other. Generally there is a medium glossy reflection 2 and clear mirror layer on top of that.
Reflection 1 can be a specular mirror coating with roughness = 0 and IOR = 1.5 while Reflection 2 may have higher fuzzy roughness = 0.3 with IOR = 2 and it will sit below the first reflection. Then a diffuse layer is placed with some color.

Hi ds, and welcome here! It looks strange. Out-of-memory is likely to be not CentiLeo error, but the one of C4D! Also the general PV render doesn't work when IPR is already running. Close IPR and then launch PV! If that doesn't help please can you send a scene with alembic inclusion to info@centileo.com for my investigations on the problem?

I hope to implement a system where shadow casts can be controlled by user per object or in some mask system. For example it's possible to make a system where object doesn't cast any shadows on all other objects. Probably it's possible to make a system where object doesn't cast a shadow on selected objects, maybe using some kind of layer system to determine the groups of objects receving or not receving the shadow casts. Indeed this feature is very much needed.

Of course! This is very much needed. And not only from Octane

RAin3D_, the free version will be available for more time, no worry

The color was wrong because of a bug with internal gamma usage. This issue and the website SSL certificate are both fixed, no warnings anymore, sorry for this
I will upload a bugfix next day.

RAin3D_, I hope within several months. That would be nice!

Thank you! Of course there is a huge list of improvements that we are going to make. Currently we are doing render speed optimization, hair and spline support. Next we will make material converter from some other renderers, add more post processing options, add more AOVs and masks for render images. We will also make object exclusion system for light sources and render images and so on

Have you seen that Cinema 4D selections work with non-Chinese symbols? This should be fixed in the next release quite soon.

There is a Facebook group https://www.facebook.com/groups/centileo
And Facebook page where we duplicate the news from the website https://www.facebook.com/centileo
In few steps later will launch the project on other social platfomrs too.

Hi RAin3D_, thanks for file! I have already found the problem thanks to you. It was related to Chinese names of selection tags and materials texturetags referencing these selections by Chinese names. I will fix it quite soon, the mistake was small
At the moment you can rename you selections to some name in English characters or numbers to make it working

Thank you, looking forward for files to test the issue

Thank you very much text-tree for kind words! And welcome here!
I understand what you are asking for. Actually currently we have no any material/shaders converter from other renderers to CentiLeo and this creates a problem to get more users. Manual material conversion is a long and boring thing and so material creation from scratch is the way to go.
However, we plan to start developing material converter from C4D and Octane, Redshift, potentially the converter can be open-source.
We will start doing this after 0.66 version will be released. Still 2 versions to wait for

These light types are simply not yet supported. This will be fixed.
Currently only those types are supported: area with rectangle shape, spot, infinite, omni.
The omni has radius parameter in centileo light tag to make a sphere from it.
Infinite light has lighting angle parameter in centileo light tag to change the softness of shadows.

Additionally there are mesh lights in CentiLeo. You can make any geometry object of any complexity and assign CentiLeo Emission material to it. In node space you just connect Emission node to the Output node or you can use a mix combination of Emission and non-emission materials and connected to Output.
There is a cylinder light shape on you picture. Just use CentiLeo mesh light, they are very fast.

Oh, thanks for finding it by yourself!
Honestly, I have forgotten about this option (send raw AOVs). This option is needed to get rid of any postprocessing from images, save them as HDRs (EXR) and continue processing them in other image processing application.

Hi ssjenforcer, it looks like you are doing smart experiments with shadow catcher!
Actually the cast from soldier shadow catcher plane behind him is a shadow. And it looks like the light source is emitting from the direction close to camera position.
To change this I suggest to add the second Sky object + CentiLeo Environment tag to the scene without HDR image file but just with a white color.
This second Sky object should be placed in the scene next to or as a child to the main Sky object. This second Sky object is placed as the override to Shadow Catcher / Matte of the first Sky object. The override settings are placed in CentiLeo Enviroment tags. The HDR file and direction of the first main Sky object may be not changed and lighting of objects (diffuse / reflection / sss, etc) will not be changed when Shadow Catcher / Matte slot is overrided by the second Sky. This matte ovveride will only affect the shadows casted to shadow catcher plane by the Sky.

Actually CentiLeo is currently constructed so that all scene objects and light sources influence on each other in a physically based way with a few overrides. Making the masks to exclude objects from camera view, making light source include/exclude lists and/or masks is thing that we need and of course it will be implemented into our engine too. Fortunatelly, this is not a very complex feature/

ssjenforcer, as for default light settings it seems you have some non-default Exposure settings or probably scene scale. When you start with a new reset scene in Cinema then CentiLeo light intensity settings produce good lighting for the objects around them without burning them. Also CentiLeo light intensity multiplier is a multiplier in centileo light tag! It just multiplies the Light intensity and color of native cinema light source object.

Yes, this is because of this. I have tested Cinema 4D exactly for this for several hours. So, it has Alpha channel for rendered image and it's applied on not only for main beauty image. It can have Separate Alpha On/Off:
1) In case it's Off then the Beauty image has transparency, but other passes still don't have (Diffuse, Reflection).
2) But in case it's On we get all images without Alpha channel and Alpha channel itself is stored as a separate image.
I think that case 2 is good, because you can re-apply this Alpha image to any image pass in AE. I don't have AE now, but I think it should be possible, it looks as something basic: the 4-th channel

In the future I will make a functionality to determine the images with object masks where you can determine the group of objects that go to any other output mask image. Also render objects or groups of objects separatelly from the other scene in image but with GI influence.

Why you background is red? Why you don't do it with ground plane + shadow catcher that can be transparent with semi-transparent shadows?

Looks strange. I have retested on my C4D. It was ok.
Please, can you send me your .c4d project file to info@centileo.com for tests with your settings?

Hi seiwen, welcome here!
Sorry for confusion, Dirt node currently is broken. We have to fix it in future releases.
