Exactly, however these tags are added automatically if the light source is created using CentiLeo menu available at the top line of C4D menu.

The "Send Raw AOVs" option is needed only when you need to output the raw (gamma=1) HDR image without any tonemapping (or postprocessing).
By default this option is off and the tonemapping is applied, but again the tonemapping can be enabled/disabled in post processing with Enable checkbox.
Usually this Raw output is needed when you later modify the image in After Effects or whatever.

The diffuse layer also has the shadow from my shadow catcher plane, and I can't find a way to control its intensity using the extractor effect. Because the diffuse also has the shadow there is always a shadow connected to my diffuse that I cannot control the intensity.

Ok, we need to develop the decomposition of the current passes into more building blocks.

At the moment you can change the weight of the shadow catcher intensity (vs shadows coming from the other light sources) using the "Matte shadow Weight" option in CentiLeo light tag for Omni/Directional light sources. There is also the similar option inside CentiLeo Environment tag

As far as I remember CentiLeo follows the native camera settings quite well and DOF should be ok. Motion blur should be tested but I hope it will merge nicely for such combinations. Anyway this adds extra render time. So need to enhance to more features

Oh no, I have to make volumetrics asap to avoid all these double render tricks

This glass around a light source use some quick skip of rays through the pure glass. The recolor may help, but changing transmission roughness to quite large values may change the noise amount in some gradual way. But it works with the least noise amount on low roughness values.

Maybe using X-Particles for the droplets? They have quite more physical effects there. We support them using all the particle physical attributes

No the cache files on disc are created for all textures you reference in the scene. This is unlimited. However the CPU texture cache is the size of memory block in RAM that is used to store the required texture parts in CPU RAM memory for faster downolad to GPU on demand. This helps to avoid loading from disc space so frequently. Larger CPU cache can be better but larger and larger size will give less extra improvement.
Without this cache we would load the textures every time to CPU and get a huge RAM memory consumption for large scenes. But with a cache we may keep them on disc and get lightweight use of RAM and leave space for some other tasks.

PS: I have moved the question to the extra topic

CentiLeo multi-pass is not enabled from there. These passes are enabled from Centileo render settings -> AOVs Tab. There are checkboxes to produce extra images. Btw there are no yet distribution for direct/indrect passes, but it will be easy to add this.
To make the output linear, i.e. without post-effect enabled you can either disable the post effects from IPR or go to Centileo render settings -> AOVs Tab and check "Send RAW passes to the Picture Viewer (gamma = 1).

Thanks for sharing the images! Btw, I like the look of the icecubes you did. However there is probably needed to improve the water droplets on the bottles, they are too spherical

I think the projection you are talking about is based on directional textrure mapped to the light source. However CentiLeo emission material texturing is currently used only for changing the area of the emissive surface with different colors and intensities. We need to add this features. However, I would also give a try to some workaround:
1) Create an object with clear glass material (roughness = 0) around your light source.
2) Add a texture to the color of Transmission.
This way you will be able to get a projected pattern you like to on the walls. And the render speed will be quite good too.

No, I don't think it will normally work this way. We need to implement it, it's on a roadmap. I think after finishing the current release there will be much easier to add such small features as that

It's like a default way of doing things in C4D itself So there are some material channel settings and there is a toggle to on/off it with a single click.

Shortly, the closest updates will get the following:
0.65 will get acceleration for render time and scene compilation (a lot of work also including quality and memory improvement)
0.66 will get native hair and spline support
0.67 will get material converters initial support

Oh very cool it works for you! I believe the texture uvw manipulation in CentiLeo is more powerfull than in Octane. However we need to add programmable shaders to make this statement more complete

Hello! I have checked your file and have fixed few material settings that I think are right now. Have a look at my screenshots and material settings. It seems the ice looks nice now. I have fixed the colors: transmission color is white, but absorption is not white and distance is smaller, check it. Also the Clamp params of render settings are increased. Also the icecubes have "Is Liquid" setting Off. For some fun I have switched on the top light source. Sorry for long waiting for reply, I was extremly overloaded with new version development

ssjenforcer wrote: also, is it correct to use a math node with add function to combine transform and projection nodes before connecting to a bitmap? I find that usually works, but I had a very strange interaction with a certain material where it didn't work until I removed the transform and only used projection. I suppose I could try connecting them to one another then to the bitmap?

Combining them using Math.Add isn't right, because they will add to one another. Correct way is to make uvwProjection->uvwTrasform->Bitmap.
Each other port inside inside Projection/Transform can also be textured in some other custom way, for example to add variation to the tiling or offsets and etc.

thrimanakatha wrote: Okay, I connected the bitmap alpha to material alpha, still same.

Have you enabled the Alpha channel in the list of channels of material? It's off by default. There are toggles for all layers in CentiLeo Material

They don't swap the surfaces. The Falloff node makes the choice of texture in use depending on the view angle.
However what you want to do can be achieved with Triplanar at some extent but with some more trivial blend function between the sides. You can rotate the Triplanar using connection with uvwProjection that has coords rotation parameters.

Hello! Just use the "Alpha" output port of Bitmap to connect with Alpha channel. On your screen you use the "Result" output port which is just RGB without Alpha.

Btw I recall there is a "randomize by object parts" option in Random node. It allows to get randomized colors/values for the connected polygon groups inside a single mesh object. For example you have some natural tree with the leaves and the leaves are disconnected from the tree trunk. And as soon as these parts are disconnected they receive different values using the Random node.
As for clones you can use MoGraph node to get access to the colors of objects. There is also a dedicated node for X-Particles.

But yeah, hopefully when you have time you can add different types of gradients as just options inside a node.

It looks like the current combination of extra nodes to do this become too complex. Probably a Pattern node can be used too with some adjustments. But we may always get these particular greyscale patterns from Photoshop. Of course I need to add these simple features directly to the Gradient node
