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.

Thanks a lot Playboy Wish you good holydays!

New small release 0.471 with a few bugfixes related to noise. Bump mapping become faster for polished reflections. I like it, and hope you like too.

Happy New Year from CentiLeo!

the CentiLeo is the magic!

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.

great news！

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.

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.

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.

All in one Tab? Ok.

Will fix

At some point I will make this and other toggles of IPR to be saved with the scene file.

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.

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?

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.

Hello!,
Any updates on the next version with multi GPU support? Can't wait to try it.. No rush or anything, just an update on where its at.. 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

Been using GPU rendering with multiple cards for a while now, (C4D user) tried out both Biased and unbiased, with and without CPU included in the actual rendering process.
I think you guys are onto something after browsing for two days in the UI of the Renderer To say, if your multi GPU stands up in speed testing and a few other add-ons happen, no doubt I will purchase the commercial product you are aiming for.. might not even wait for the add-ons if the 'noise' of Octane doesn't pop its head up.
Not to say 'Fog' wouldn't be good, a base material library, distributed rendering ect ectera..
but the speed now is a plus for sure.

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.

Thanks for the welcome. Might I ask, does the renderer have a 'emitter channel' yet... to give Texture emission- turning Objects into light sources with that material applied having said channel? Tying to get used to the UI, lol. After trying a dozen render packages slightly different I might be missing something on this subject.
Awesome what the package has for the bump channel, I never would have even thought of such application, very ingenious.
