Vraymatnetprop.mse ((top)) Direct

Let a V-Ray material network be represented as a directed acyclic graph ( G = (V, E) ), where each node ( v \in V ) corresponds to a material component (e.g., VRayMtl , TexBitmap , TexMix ) and each edge ( e \in E ) defines a connection (e.g., diffuse map input). The output material ( M(G, \theta) ) produces a rendered image ( I_\textrender ) under fixed lighting ( L ) and camera ( C ):
