the hard light or overbright HDRI map will cause the white clay where should be transparent in the transmission channel,or i misunderstanded something.
Hi Play boy! Very cool progress with pics! Seems there is some SSS there?
Need to see example to understand the problem. But in general if you make a coating reflection layer on top of transmission then there will be a highlight and it should be larger with larger roughness value.

and the "shadow catcher" need a very hard light to recive a clear shadow
Do you mean a light from HDRI or another light like area/omni/spot/directional? If you use "area/omni/spot/directional" to illuminate the shadow catcher plane then they deposit the light to it taking into account where the shadow catcher shader was attached: to diffuse or reflection e.g.
If you want to get a shadow on shadow catcher from HDRI then it is indirect GI contribution only, hence very soft.
Also need to see an example of the issue.
Btw, I am going to make a slider for each light source and EnvMap tag too: Brightness and color tint for shadow catcher - similar to the settings for reflections/base/transmission.

Hi Play boy! Your pics are nicer and nicer and continuation is needed It seems reflection highlights are ok now. The eyes are cool!
I remember about the promise to do "Illuminate shadow catcher" option. Will do it for sure.
Based on this pic we aslo need very much natural hair geometry render and corresponding shaders.
Right now we are working on multi-GPU - this is an essential part to go out of our current "toy" status.
Hi Sup, but Anton doesn't share his scene. He tested CentiLeo with it and has shown few pics. Don't worry we will implement procedural normal map flakes

Hi guys! How I can set the value of displacement? I have a bitmap input but I dont have a unit of scale(like c4d displacement), It can be done per material or only globally? sorry my poor english.
Hi Rodrigo! The measurement values shoult yet be implemented properly in our renderer.
Right now displacement is tuned inside cntlTexture which is attached to displacement slot of Multi Material. However, currently displacement mapping is still in progress. It has problems in animation, some times looses triangles and tesselates slowly (tesselation happens only in the first iteration of render). But it has potential to become a perfect solution even for vector displacements in the future.

Light lister script by Ali Kavyani:
Change Log: cntlmax 0.471 alpha (2016 Dec 31)
[core] Improved render speed for scenes with many lights and rough reflections
[core] Improved render speed for bump mapping on polished surfaces (with roughness close to zero)
[core] Fixed fireflies in few situtations
[cntlmax] Fixed crash when click “View Image” in cntlTexture and go up. Change Log: cntlmax 0.470 alpha (2016 Dec 25)
[core] Added post-processing contrast setting. 0.5 by default, it makes the image more realistic
[core] cntlStdMaterial: glossyness usage as alternative to roughness (if checked then roughness is replaced with glossyness and treated accordingly).
[core] cntlStdMaterial: weight*color mixing mode similar to other engines
[core] cntlFalloff: parallel falloff mode
[core] Faster many-bounce internal reflections inside complex glass object.
[core] Roughness remapping. Now all the range 0..1 is more interesting unlike before when most interesting values were close to zero.
[core] Many bugfixes for material behavior when roughness is changed. Now the highlights are changing smoothly for small change of roughness.
[core] Fixes environment map brightness when seen through reflection
[cntlmax] Post-process can be performed when render is paused

Haven't yet updated the version because still digging in the bugs, such as not very smooth shadow change when changing roughness of transmission. One similar but very subtle problem with reflection roughness, etc.
Hope to do it asap and then move to further improvements.

by the way,shadow catcher was not working with HDRI map light(just AO left) or i misunderstanding something.
Yes, it's true. This is actually correct, because the shadow catcher plane shows photo of HDRI which is considered to be lit by itself already. That's why we why we don't add light to the plane again. What you call AO is GI. Other lights illumination is added btw. E.g. you may add infinite light with cntl tag to tune light you want.
But I also want to add the option 'Illuminate shadow catcher' to any light source and also to Hdri so that it will be able to break few rules/physics

Konstantinos Despotis, thank you a lot for upload! I notices what you are talking about. Indeed it's a bug that is clearly visible on your shaderball (I guess it's from Corona In our few test scenes the lighting conditions haven't given so obvious picture of this bug.
The roughness should be not linear. I will test it face-to-face with other engines in order to calibrate it better.

before I fix it the workaround is to attache cntlBitmap where you want and then instead of it place the cntlColorCorrect And the new cntlColorCorrect will get old cntlBitmap as a child. With the same approach all the other shader replacements are working. Old shaders become children of new shaders by default.

This is in our plans for sure. But can't start working on it before we do multi GPU and improve displacement and hair. Also need full support of native TextureTag.
We also need to improve own procedural shaders.

there is something wrong with the reflection and the reflection weight also the roughness needs different scaling, at 0.1 it is already too much, look below it seems at 0.1 roughness the weight plays no role anymore, neither does ior, only if I bring the diffuse weight down to 0.5-0.7 the diffuse looks normal, but then If i raise the ior the material gets much darker and in the corners wh ere it should be brighter because of reflection it gets darker, it is confusing, and I know how to make good materials in Vray, Octane and all the rest of the renderers out there so it should be easier for me unless I'm missing something. Edit:It happens between 0.01 and 0.011 or more, it jumps to more than it should I think it is a bug?
I agree about the range of roughness. Should remap it. Currently the idea is to map current roughness=0.5 to new rougness=1. What do you think?
It seems there is bug and need more clarifications. I mean

Edit:It happens between 0.01 and 0.011 or more,
Please can you share your test scene where the error is clearly visible?
E.g. in 2nd and 3rd images you have roughness 0.1 but when you have Weight = 1 and IOR like 1.4 then this value of IOR produces increased weight at surfaces with orientation close to 0 degree and decreases weight for surfaces oriented towards the viewer at 90deg. However when you increase IOR up to 20 or 100 then there should be uniform reflection under any angle of view.
But when you decrease the Weight then it scales down what is given by IOR. E.g. on you 3rd image you have increased IOR to 20 (it's everywhere almost a mirror). But the weight is 0.2. So there is 20% mirror and the rest is for Diffuse.
I have played in our test shaderball, it seems to be working as planned.

How they are connected with the Mobo? Based on practice CentiLeo out-of-core geometry is best working with PCI express x8 or x16 Gen 2 or higher.
PCI Express Gen3 has 2x better bandwidth and is very cool. E.g. PCIEx x4 Gen3 should be like PCIEx x8 Gen2.
I also think that connections with PCIEx x2 or even x1 are not very good for heavy geometry scenes that exceed VRAM a lot. They will work but not so well as fat PCI express channel
Hi Konstantinos and welcome to our board!
What you are talking about is in our plans and we try to make it asap. Hair support will appear earlier than Node based editor in C4D.
We have light mixer btw, see examples from version for Max:
In C4D it's working the same.

Still have to fix the problems with animation recording. It's quite a task which will lead to very cool results and optimized scene load to renderer for each successive frame. Will be ready soon.

Change Log: cntlc4d 0.462 alpha (2016 Dec 16)
[core] Now the glass is created by setting only transmission.weight to 1 and you don’t
need to disable default Diffuse.weight to 0. According to new convention the weight of
transmission layer overrides diffuse. If you want to mix transmission and diffuse then you
should to make transmission weight less than 1. This is similar to other engines.
[core] Fixed incorrect glass rendering with IOR values larger than 1. And now it looks
much more beautiful.
[core] Fixed “black highlight” bug in subtle rough reflections.
[core] Fixed issue which caused slow render when there are many light sources with crazy
different areas and intensities.
[core] Added option “Contribute to only GI” to the light sources which helps to add more
indirect light to interiors without increasing the number of ray bounces. Increases the
speed of interior rendering, flicker-free, similar to portals accelerator for GI.
[C4D plugin] The camera (from CentiLeo menu) is created with position and orientation of
the current camera.
[C4D plugin] Default environment color is used if there are no any light sources in the
scene.
