i am pretty new to all this as well so a few cinema 4d tips will also help
BUT
whenever i render the whole scene has so much grain how do i fix it ? or rather change it ?
and does normal c4d lightning suppose to not work in centileo render?

Hi ron134,
To get rid of noise that you call grainy you have to increase the number of render iterations in CentiLeo render settings. Also CentiLeo uses own materials (CentiLeo material and all sorts of textures/shaders). And it uses Cinema 4D light sources as the base but they need to be connected with CentiLeo light tags that extend the base light source with several extra settings available for CentiLeo. Sure we need to launch a complete documenation about the software, we will do it after finishing the next technical release

do you have a small guide or a library for the materials as of now before the next technical release ? |

No yet, there are plans to make a library of materials. However, current material engine is pretty much similar to C4D native or Corona or Octane. Same values of material parameters produce the similar result

i am having some issues with the material first i got no idea how to use them 2nd no matter what i do i dont get the reflective result i want it just keeps being like a black plastic no matter what i change lights do nothing as well |

If you use CentiLeo node materials then each material has several layers: Reflection1, Reflection2, Transmission, Diffuse, SSS, Translucent, Alpha. Each layer has it's own paramers such as weight, color and roughness, ior and others. Additionally there is a tab called "Inputs" it has the list of all material layers that you can enable/disable with a flag. This is a standard thing as in C4D native materials.
If you use Menu based old style CentiLeo materials (in Cinema 4D older than R21) then there is a tab called "Basic" where you can enable/disable all material layers.

Make sure you also have a centileo environment object. This is the only way to have light rendered. You don't need an HDRi mapped to the texture, but it gives better lighting depending on the scene. They are free online. HDRi Haven, etc. As for the materials, adjust the reflection IOR and roughness (colour roughness barely makes any difference, so only worry about reflexion properties mostly). IOR is how reflective the surface is. Increasing makes it more mirror like. And if you want a chrome mirror surface just max out IOR and disable the diffuse node entirely. Reflection roughness of 0 will make the shinier surface with max gloss. Think of a plastic surface that is very shiny, and max roughness makes it like a plastic surface you cannot see yourself in like a mirror. When you add a centileo material you could double click the icon that gets created and enter node editor. I suggest learning nodes if you want better materials with surface imperfections. greyscalegorilla has great tutorials. 3dFluff and Eyedesyn have really good creative and helpful tutorials on YouTube as well. For quick tips use QuickVFX or pixellab. Once you learn the basics of materials and lighting setups it will be much easier. I suggest starting learning animating keyframes and then dynamics. Those are the most fun to play around with. Cloner objects and sweeps and deformers. Lots of things to learn and useful to create with. But be careful with softbody dynamics (squishy objects) unless you want to crash your program

You can drag&drop your images from windows explorer to node editor and CentiLeo bitmap will be auto-created. By default it uses texture projection determined by TextureTag of the object where material is assigned. However you can change it using uvwProjection node where you can either use a procedural texture mapping coordinates or reference one of UVW Tags that are assigned to your object. Sure, we need to write a manual for shaders of CentiLeo because there are a lot of nice things that can be done. Also during shader writting I tried to follow the similar practice as native Cinema 4D nodes, so they can be somehow similar. Do you want me to share a shader ball scene with some materials? ssjenforcer, thanks for help to new user!
