There is no yet implemented "emission channel"... Will try to implement it in one of the near future versions.
However, one small trick is possible if you apply cntlConst shader with large value to diffuse channel. This way it will reflect a lot more light.

In bump channel it is possible to combine black&white bumps and normal maps.
However there is some small drawback is that when you apply colorCorrect on top of bump shaders then you need to extend the range of "clampA and clampB" values to negatives. Our bump channel also needs a shader for procedural flakes.

Hi Mike, welcome to our forum!

We are currently working on the multi-GPU and few other improvements for 0.48 such as better IPR, better look and better out-of-core.
This should be more interesting. However, many more things are planned for alpha version.

Please, don't hesitate to write what you want to see in the renderer! We listent to it. However right now the amount of accumulated requests is so large that we can't do them all immediatelly. But step by step these requested features will be performed. And of course we need to make the integration with C4D better, tighter and more native.

For example, I am desperately can't wait when will work on hair&fur and particles Because it is hard and very interesting. The other things are much easier.

Some small internal progress, we have improved geometry data storage by around 30%. Now more polygons will fit into geometry cache and it is also good for "out-of-core" case.
Still working on the rest of the TODO list.

I've read also about the hack attacks, hope they didn't delay much of the progress.. keep up the good work, and keep us updated! Konstantinos

Hi Konstantinos,

That attacks don't delay anything. This is just an unpleasant thing that my friend is working to fix.

The work on multi-GPU is going well. It takes some time because we have quite large pipeline of parallel sub-programs inside the renderer.

There are also a few things that should be done in a renderer that 1) should fix not-loaded procedural objects for Picture Viewer, 2) and would like to hide and automate that 2x manual renderer acceleration trick (see http://centileo.com/forum/forum19/93-recomendation-to-increase-render-speed-and-reduce-lags) which is important for final renders and animation.

0.48 will be published when everything will be clarified with it. I think it may take at least 2 more weeks or something like that.

Maybe you have read that we made some GI acceleration (see http://centileo.com/forum/forum21/106-status-of-preparing-centileo-048-alpha)
And we also made support for up to 4 UV sets per mesh (in Cinema terms up to 4 UVW tags) that can be selected in any texture. After 0.48 will continue in this area to support more procedural texture mappings and transformations as TextureTag offers.

The goal is to make 0.48 closer to "production state" and then to continue implementing features requested by users. The path is very clear.

Hi Theia,

Currently we don't yet support native C4D shaders but have own set of shaders. However, we have IPR mode which understands everything (i.e. it responds to material, shader, lights, object motion and polygon editing inside object). This IPR is final frame quality and has button to transfer image or beauty passes to Picture Viewer. Since upcoming CentiLeo 0.48 the responsiveness of IPR will be further improved.

We plan to implement support for native C4D shaders as much as possible. But right now it is necessary to make more core features like motion blur, mesh emitters, hair, massive particles.

Thanks Gael! Yes, dark regions are rendered better now. This is also important for further post work based on outputted image layers.
Also it is possible to enable one "fake" feature that helps rendering darks even better. The light sources have the checkbox "contribute to GI only". If checked then the light source contributes to GI only (i.e. to the secondary diffuse bounce) as you can see in the recent post by Ali http://centileo.com/forum/messages/forum17/message461/98-centileo-for-3ds-max-0462-available#message...

However, pictures in the current thread have no enabled "contrib to GI only".

Hi Rodrigo,

Very big thanks for your feedback! Not easy to do everything early. But step by step we will work on this.

So, you want to have Translucency in the separate Tab. Right? Do you think it needs the "Weight" like other channels?

Rodrigo Bitencourt Rodrigues wrote: Std material can be only with diffuse and an reflection coat on by default.

I aslo thought about it. Will probably swich off checkboxes of the layers "Reflection 2", "Transmission", "SSS" but make their respective Weighs = 1. When checkbox is enabled the weight is already there.

Rodrigo Bitencourt Rodrigues wrote: We need a bump intensity slider to positive and negative values(like cinema 4d standard material.

Ok, will extend the range of the main bump strength slider. However now it is possible to do it inside the bump texture in cntlBitmap when you play with out_rangeA and out_rangeB. E.g. when you make out_rangeA=1 and out_rangeB=0 the bump goes inverted. Similar effect happens when out_rangeA=0 and out_rangeB=-1. It's also possible to make it negative with cntlMath shader with mutliplication by -1

Rodrigo Bitencourt Rodrigues wrote: Our displacement need a scale input.

It has it actually. When you change the value of out_rangeB from 1 to 10 then displacement become higher 10x. When you make out_rangeB=-1 it goes under the surface and so on. When you change out_rangeA to the value other than 0 you can change the "sea level". It seems we need to make cntlDisplacement shader with respective naming convention.

Rodrigo Bitencourt Rodrigues wrote: Our material can respect the material tag uv inputs? its very important.

Right now material textures can use just the first UV tag of the mesh, the spherical and triplanar mappings.

Quote
Rodrigo Bitencourt Rodrigues wrote: c4d allow to use multiples uv tag per object

I hope to add support for more UV tag mesh projections next version. Right now I think about making 3 UV tag mappings per mesh selectable in material shaders. Max 3 mappings is usually seen in other engines. Maybe we will be able to do more than 3 UV tag mappings. How many are needed?
Also need to add support of TextureTag params too.

Rodrigo Bitencourt Rodrigues wrote: We need a compositing tag, a object buffer system and a material id output.

We plan to do it in a couple of versions. There are many possible ways to do it. Need to figure out the most convenient one and do it. What good example reference would you recommend?

Quote
Rodrigo Bitencourt Rodrigues wrote: The displacement channel can be in the std material too?

Maybe yes. In one of the few upcoming CentiLeo updates there should be version with displacement improvements (there are a lot do there). There is also a chance to move displacement settings to the Tag of the object (and Opacity which is found in Multi Material will also probably go to the Tag). There is aslo a chance the displacement will understand shader networks but don't promise yet.

Rodrigo Bitencourt Rodrigues wrote: We need a alpha channel to our material.(not like the multi material, we need one to hide some parts of the model.)

Ok, will make separate Alpha channel (limited with "specular ray depth" param of the render settings). Right now such things are implementable using Transmission channel with IOR=1 (but it will be limited to maximum ray depth in render settings) and it can be done with Opacity slot (see in cntlMultiMaterial) which has unlumited depth (but limited to only cntlBitmap input and discrete nature: the surface is either visible 100% or not).

Hope to see comments from other guys on the subject too, especially on the number of required selectable UV tags in material textures.

Sure Ali, I also have noticed that after roughness = 0.6 or maybe 0.7 the values are useless also because of some energy loss.
One option for us is to re-scale the input roughness by 0.6. But the final decision will be after adding GGX, because the highlights should look different with it.

Hello everyone!

Need to post how things are going since there are now news from us for 3 weeks already

We are working on many improvements including further noise reduction, multi-GPU, nicer material reflection look and nicer tone mapping.
E.g. the open question is whethere GGX reflection will be added or not and when we will finish multi-GPU. Hope to do it ASAP.

Few pictures about development in progress:

These are 15 min renders with scenes complex illumination interior with HDR lighting coming through 3 windows. HDR map has sharp bright sun drawn in it.
Windows have lattice to make obstacles.
The other 3 light sources are covered by some geometry: 2 lights covered by glass vases (on the left) and another one is covered by cylinder on the right.

Comparison presents "Another GPU engine", old CentiLeo 0.47 and current 0.48. Everywhere portals for windows are used, 6 GI bounces, and other settings are tuned for better performance in both engines. One 970 GTX is used for these tests.
Materials and shaders have the same complexity stucture in both engines, same amount of textures but the colors of floor and furniture are slightly different.

CentiLeo 0.48:

CentiLeo 0.47:

"Another GPU engine":

Hi Ali!
It's already added. Here is the difference between 0.47 (top) and internal 0.48 version (bottom). Everything is diffuse. 0.48 has Oren Nayar diffuse with roughness=0.4

play boy wrote: 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.

Quote
play boy wrote: 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.

play boy wrote: the CentiLeo is the magic!

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.

Rodrigo Bitencourt Rodrigues wrote: 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.

Hello everyone!

Merry Christmas to those celebrating it today!

CentiLeo 0.47 alpha for 3ds Max 2014-2017 is available.

It has a lot of quality improvements. Post-processing contrast adds nice image feeling. While most work was spent for material behavior improvement and bugfixing. Really many things were polished in cntl std material.

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.

Konstantinos Despotis, I have fixed that bug when jumping 0.01 to 0.011. It was a stupid mistake

Now the roughness works like this: animated roughness from 0 to 1 (no bug and better mapping):
https://www.dropbox.com/s/hbmo4zgw368jt9n/roughness.avi?dl=0

This is anumation of IOR changing from 1 to 4 (when become large it looks more like a metall):

Will upload it today deep evening or tomorrow together with some other fixes
