It is important to understand the concept of the VRAYforC4D material to understand its power and possibilities.
The VRAY material consists of 15 material layers, Layers are stacked one above the others. Maybe the easiest thing is to imagine them as a photoshop file with 15 layers.
Most of this layers can have its own mask or transparency. If parts of one layer are transparent the layer below shows through.
The VRAY material can be edited through the Attribute Manager (AM) or through the Cinema Material Editor. I personally recommend using the Material editor or an extra AM as it has normally more space to see all settings in the Vray Material.
One the left there are the material “layers” or channels, within the channels You can load textures or Cinema 4d shaders just as you probably are already used to it from Cinema 4D. one the right side you have the vray specific settings. almost all aspects can be controlled via shaders and textures.
The Material preview is done in real time, you can use all preview types like in normal cinema 4d (sphere, cube, rounded cube, cylinder, double knot etc…) and
The double knot p.e. is very good for previewing reflective materials like metals.
Right click on the preview to choose the size of it (here i used “huge”), there is also a drop down menu to select the preview quality to adjust it to your needs. the preview is done by the native vray engine and uses all cpu in your system it is fully multithreaded.
To render in Vray one must use the VRAY Material, there is a one button translator in the plugins menu to convert c4d materials to vray materials to start rendering in vray, know you can render with native c4d material, but VRAY Materials have more options.
Name – here you can enter a name for the object.
Layer – If an element was assigned to a layer its layer color will be displayed here. This field reflects the layer color in the Layer Palette. You can drag & drop layers from the Layer Browser or similar layer fields onto this field. You can also assign layers or remove elements from current layers using the menus located behind the small triangle.
Overridable – when you use Override material options in Global options, you can specify some materials that will no be override, like glasses, curtains etc..it useful for preview vizualization of interiors.
Material ID – ID of material object for matte rendering.
Color ID – XXX.
Preview Subdivs – controls the quality of glossy reflections on material preview. Lower values will render faster, but the result will be more noisy. Higher values take longer, but produce smoother results..
Preview Quality – quality of material preview in preview window.
Map Preview Size – set here value for preview material gamma, it only affect preview in Material preview windows and have no effect on rendering of final image.
Convert C4D Bitmaps – converts C4D Bitmaps to V-Ray AdvBitmaps.
Bake C4D 2D Shaders – bake C4D 2D shaders to usuable textures.
Bake Resolution – bake resolution of textures.
