Hi coooooolin! Welcome to CentiLeo! Thanks for suggestion!
I think we can do this, this is possible and I will help. Actually there was a discussion some time ago how to make translation for node editor in the topic with China users
Please look there! If that doesn't work I will create the template files and will start entering valid Chinese translations instead of English and you will check them :

Thank you Rodrigo, and welcome to CentiLeo! At the moment the new release is under testing and bugfixing, it's on the edge. Will release it very soon! It will get very good speedup, especially on new cards :)
How to use Subsurface Scattering properly?

Hi ssjenforcer,
You have found perfectly right that mixing separate pure red, green and blue channels result in a white color because these 3 subsurface channels are combined using weighted sum. You can make your weights arbitrary, but they will rescale accordingly. There are three of these layers just for flexibility, so that you could make one layer thin and and another layer thick changing the radius value accordingly. For example for skin surfaces it's nice to make one red layer with larger radius to get this subtle red lighting effect when the light is behind the skin object.
Actually this SSS is like an extented Diffuse. For example you can make SSS with red/green/blue or white/white/white colors and zero radiuses and compare it with white Diffuse. They will be the same. Later you can change the colors/radiuses and weights and make a different look.
Usually SSS is combined with reflection layers to make a tint layer. But combining with Transmission or Translucent is also possible.

In the future I will make a so called random walk SSS solver to get more precise SSS for small thin object parts with large SSS radius.

why use two reflection when making metals,and does Reflection 2 use the same IOR as Reflection 1does?
It's defenitelly up to user to use one or two reflections. You can setup differernt IORs and roughness for them of course. This is done for artistic freedom

Hi Transfangames,
It's pretty easy and is the same process to how it's done using native Cinema 4D materials. But instead you use CentiLeo materials.

In case you use old menu based CentiLeo material interface:
You simply create CentiLeo material, then you go to Diffuse slot and to the Color slot and click the black&white checker button and select "Create new Bitmap" among other shaders. For Bitmap you choose the image from your files.

In case you use node based material interface you have to select CentiLeo as a renderer in Cinema render settings or choose CentiLeo node space.
Next you create Node material (CentiLeo material will be created). Then you open node editor for this material. Using the menu for textures you can create the CentiLeo Bitmap node, choose the file for this node, and then connect the output of this node to the Material Diffuse Color slot. Alternativelly you can drag&drop your image to the node editor and CentiLeo Bitmap will be auto created, then just connect it.

How to change sun light colour? The actual sun object., (just figured it out; colour tint :( )
Administrator  Posts: 774

The sun color can be changed in the light main object color itself. When you create the Sun tag for this light object there is checkbox to change the object color automatically depending on the selected day time. Also there are multipliers in Centileo light tag as you have noticed. If you see some difference then check the IPR post fx settings on the right panel of IPR, maybe you have applied some tint for the image.
Does centileo work with s26?

No, we haven't made these tests. But the next large release of 0.65 will support S26. Actually it's possible that R25 plugin copied to S26 may work, but there are no guarantees.
How to uninstall CentiLeo?

Yes, to uninstall CentiLeo out of a project the CentiLeo ID tags should also be removed manually. Actually we create them and make invisible using CentiLeo to track for geometry changes in the interactive preview render mode (IPR).
Have you considered using Random Walk SSS?

Hello jacklia, and welcome to CentiLeo! Yes, sure I love Random Walk SSS personally and will definetelly will integrate it to CentiLeo and hopefully soon :)

I unchecked "Send RAW AOVs to Picture Viewer" and now it works.
So if I want to use post-render settings I need to have that unchecked?
Oh, I have forgotten about this option, of course this is the reason. It just kills the post and sends RAW image to PV with the intention to make post in the other image processing application.

Hi, they should affect the final image. Do you have any post render settings override on the camera or no? I will check this on my tests

I hope it is coming along well
Well, it's so long under development, that's too much, too complex. And no new features. Only fixes and some important render optimizations for hard cases. Need some bit more time and will launch it, hopefully without major bugs :)

Please, sorry for long reply!
Currently the AOVs/passes functionality doens't support a general subdivision of shadows/non-shadow passes. At the moment the separate shadow pass can contain the shadows casted to the "Shadow Catcher/Matte" material and that are outputed to the "Alpha channel" pass.
Later I will add a lot more functionality to AOVs/passes including many kinds of masks and beauty pass subdivision into elements.

Hi ssjenforcer, sorry for delayed reply!
The Transparent background option removes the HDRI image from the main render image. You can save this background if you check the "Bacgkround" pass.
But maybe your issue is related to the "Alpha channel" option in Render->Save option?

Hi Sang! Thanks again for your scene! Sorry for veery long reply, I was too busy developing some renderer parts.
I have looked there and detected the reason of low performance. Basically everything is nice except of the emission material "LED_Beige". This material is assigned to selection of the building which forms a light shape around the building of the very irregular form. In fact the internal emission algorithm doesn't divide this shape too deep and hence doesn't result in the nice noise reduction. The other emission materials work fine in the scene: the emissive objects inside the building and the stree lights, etc.
The receipe to fix the issue:
1) Reduce the emission power of only "LED_Beige" to something less than 10 and make importance sampling Off. And you will see how the noise would be reduced a lot.
2) Manualy divide the selection of polygons that have assigned LED_Beige into multiple different objects of simpler shap.
3) Wait until I make #2 as an automatic internal process as part of more complex noise reduction algorithm. The main concern is memory but there are some ideas. Basically this process is implemented in the renderer core, but it doesn't divide to deep as is needed for such an object. So the further improvements are needed.

C4d Baked displacement maps

Displacement maps should be baked to high precision format 16-bit or 32-bit, these can be png or tiff for example. If you choose jpg/bmp you will see this

Nice attempts btw :)
Actually you may build the bump map based on Layer shader node with several layers of differernt Noises each of them with different granularity for zoom in / out
Also displacement map can be usefull here as well
