Sure there will be a manual with nice examples and a material converter, this is a must have. We tried to make CentiLeo very easy to use, we will add a lot more features to cover everything. The remaining part of development is not so large.

Probably not a bug. CentiLeo uses Focus Distance value from C4D native Camera object. This value can be changed by C4D native tools, animated and targeted if I am not mistaken.
On top of that this Focus Distance can be changed inside CentiLeo IPR window with [AF] button (auto-focus). But this [AF] change will not make the focus distance to follow some object in focus. To do this, Cinema tools can be used, Cinema's autofocus with picker button.

Hi Hao and welcome here! Caustics are not yet supported. They will be integrated in a longer term future as an additional render layer without any settings, but with a separate checkbox to add caustics per light source.

Hi! The own manual is not yet ready. Still doing the release dedicated to render time optimizations.
As for displacement, then here is a recipe:
1) CentiLeo Node materials
2) CentiLeo Output Material, it has Displacement slot
3) Connect Displacement texture to to Displacement slot.
4) If you are working with CentiLeo IPR click "Tess" button every time you change displacement settings or change camera position.
5) In Picture Viewer no need to click "Tess" buttion - this is processed automatically each time before rendering a frame.

Hi, there are 10s of factors that influence on rendering speed for this or that scene. There are scenes where CentiLeo is faster than other renderers, and there are also scenes where it can be slower. At the moment we are working on render time optimizations to make it a lot faster in more cases.

Please show your example screenshot of a scene where the render speed should be improved.

Hi faxx_, welcome here! These features are not hard, they are in mid-term roadmap. At the moment we are working on render speed optimizations and hair/spline support.

penguin, hi! And welcome here! Please, can you send me a file for tests? To info@centileo.com It looks strange, I want to fix it.

This is very useful for making the ground render as alpha so I can composite objects into after effects. I hope this feature is available now or soon, or it is a deal breaker for me to switch to this engine. I'm looking forward to starting to use this centileo. Also, I need to be able to catch shadows on the same ground plane and render out a shadow pass. Is this possible?

It seems all you want is possible right now. Just make a ground plane, drop a material with "Matte / Shadow Catcher" option On. Swich on Alpha Channel AOV - and it will render shadows on the plane, but will not show the plane in alpha channel. Also you can use Sphere (Omni) light sources or HDRI Sky with Shadow Cacher intensity to change the strength of shadows casted on matte/shadow cacher object

Translation software seems to be very nice btw

they will work if you do this setting as described in the post

As for Object visibility tags and the other related things I will fix them after I do more technology improvements. Speedup is coming

Hi Cheese! Yes Dirt is not working now for couple of latest updates, I will have to fix.

Thank you very much! How do you use our renderer, what kind of images do you produce? The idea is very cool

That's very cool we win over Cycles-X, I hear this not for the first time. I have very high opininion about Cycles-X, they are very very good. And the truth is that currently am optimizing CentiLeo, it will be faster
As for material/texture representation in a viewport - I don't really know what is better. Sometimes ago I thought that current solution is nice, I also think to use Diffuse channel textures there by default, but this will load textures to viewport by default and will make the Cinema part of pipeline more heavy, so I kicked textures connected by default and left just a color to distingush the objects from each other.
Anyway there is IPR that displays everything and next version it will get viewport mode (with ray bounces = 0) to display just textures without lighting. And it's super fast, real-time, no noise, allowing to quickly work on texturing, UV layouts with much shorter waiting

Here it's better to connect Emission to Primary material slot, the other reflective material should go to Secondary material slot. The Primary Amount slot should be connected with bitmap that describes Emission mask.
Also the Viewport Color should connect not a material but a texture node (a bitmap or something else). It's for testing purposes in a viewport and you can check any texture node you want.

It's possible even now if you are working with node-based materials. You simply need to connect your texture to the Viewport Color channel of CentiLeo Output material. By default nothing is connected there, not even diffuse.

Ok, let me make an example for you, just very soon

Hi, by default these assets don't work because they appear using specific Cinema 4D paths, they are not like existing file paths. But these assets can be used because they have file ids. The only way to launch these assets is to go to CentiLeo Hardware settings. You may find link in render settings or in common Cinema Preferences. There you will see the checkboxes for GPUs that are used and the Texture File Cache folder. By default the texture caches are stored together with original files (like JPGs in your win explorer), but you may change and store the texture caches in the common single folder, please select this option and choose the folder path. If you do this the virtual files from Asset Browser will create the caches in this common cache folder and they will work correctly in new CentiLeo version.

Hi! It would be better if you show an example of what isn't working.
You may add your image mask to the weight of transmission channel. Emission doesn't have the weight. But if you use CentiLeo node-based materials you can make a Mix Material and connect your image mask to the primary amount, then connect Emission to primary material, then connect reflections to secondary material of MixMat. This way the image mask will control the visibility of Emission.
You may also recreate this node setup in old-style materials if you create a multi-material and plug Emission and Reflection materials there

Done

Sure, use CentiLeo materials. We have implemented the CentiLeo nodespace, they are node-based same as native Cinema materials. The native C4D materials are not yet supported because not all their features are corresponding 1:1 with our materials. But later this will be fixed.
