    You have several options to create your own MDL materials, either variations of existing ones, or completely new MDL designs.

    To construct your own MDL material quickly within Cinema, you can take one of the existing MDL materials, then adjust its parameters, add another MDL effect to it, and save it out. The plugin comes with the so-called MDL Core Definitions, a collection of "layer" nodes, which have been designed for this kind of workflow. An example would be, to add a "dust" layer on top of a polished finish, or, as another extreme, cut a pattern into a material. We are working on a tutorial for this kind of workflow inside Cinema, btw. To get started, we suggest to download the NVIDIA vMaterials library with 100+ designs, and go from there.

    Another option is, to create MDL materials in Allegorithmic's Substance Designer 6, and bring this design to Iray in Cinema via .mdl file exchange. This should work out of the box, since the required MDL components (MDL Exchange) are installed together with the plugin. In contrast to the "layering" approach above, Substance Designer allows you to use the quite established shader-graph-like approach by plugging together input/output parameters of nodes, a workflow more suited for artistic shading effects rather than for PBR material construction.

    And of course, you may write your material in MDL text form, and then import it into Iray for Cinema.

    For the future, we focus on easier material workflows directly within Cinema, and also better ways for transition from third-party materials to physically-based MDL designs.

    We are prep'ing for small video tutorials and will post announcements here when they become available.

    For now, we have few threads on the topic, like

    Dust-Material
    How-to-add-grunge-maps-or-bump-maps-to-MDL-materials
    Displacement-with-Iray-and-MDL

    BTW, we are going to simplify the material layering through "stacking" the Cinema way in the upcoming major plugin update. Our tutorials will cover that new workflow.

    Hi Steve,

    giving the (C4D-) users acces to an easy workflow for creating own mdl-materials is vital for a professional usage of Iray.
    All renderers who don't provide that are more or less useless. Most times nice advertisement examples, but when yourself put your hands on it, you cannot create anything good.
    The MDL thing is more or less fairly cryptical for me, and under the examples is nothing that I could use for organic character renderings.
    F.e., Arnold's big growing success is mainly based on the simplicity of usage. Easy to use render settings, and moreover, a powerfull and really easy to learn and understandable material tree-editor system with lots of power to create any material you can imagine.
    The Iray integration in C4D is more or less working, but far away from beeing really usable like Arnold.
    On the other hand, you did a really good working Iray integration in DAZ where one can fairly simple adjust materials there to one's needs.
    So why that not in C4D ?

    Iray is really a renderer with huge potential, especially when you can integrate it also in VR-capable engines like Unreal 4, but having an understandable and usable material system is essential, otherwise it will be exclusive to some rare NVIDIA-Freak-Gurus, but not for the average artists.

    Totally agreed!
    We do see a convenient MDL editing workflow "inside Cinema" as the next big milestone. Easier to find, preview, apply, edit, layer/stack, and share.

    The good news is,
    the MDL materials are fully functional, customizable, and can be layered easily within the current Cinema UI.
    So the plugin offers the fundamental features to create your own material designs, and being able to share it with others.

    Best,
    Steffen
