NEW IN R21
General information about Material-Nodes can be found there.
ProRender has several of it own nodes that work with the renderer. You will find only these described below. Many of the standard nodes from R20 (e.g., many of the Math or Text nodes) also work with ProRender. The standard nodes are described in the description of the individual assets.
Contrary to the Standard/Physical renderer nodes, the ProRender nodes do not have the Context functionality.
Instead, only a UV port is offered for all nodes for which it makes sense to have. This UV port only affects the node to which it is assigned (not like Standard/Physical renderer nodes that also affect previous nodes). This reflects the local context of the old nodes.
ProRender nodes do not support the concept of RGBA ports. Instead, 2 ports are available, one for RGB, one for the alpha channel.
Several ProRender nodes’ input ports (e.g., Noise and Ambient Occlusion) only accept constant input values, i.e., items that are evaluated for rendering only will not work here.Cinema 4D will put a red frame around these items, color the ports red and us red connector icons as error warnings (these types of constellations will simply not work).
ProRender nodes basically have a defined maximum number of ports. Variadic inputs, e.g., as used with the Layer node (here any number of layers can be created) cannot be used with ProRender.
