PBR Render

In: Material Filters/PBR Utilities

Complex

Description

Renders a PBR material onto a sphere, plane or cylinder using Image Based Lighting (IBL).This is a render-engine inside a node, which can be very useful for generating thumbnails, previews or 2D assets. It is not a render like the 3D view, but an actual texture being generated in your graph.

This node requires at least a full PBR material to be plugged in. Ideally you make use of Link Creation Modes to connect the material to PBR Render. Additionally, you will need a spherically-unwrapped HDRI environment for the render to calculate lighting from. Materials for testing can be found under PBR Materials, Environment maps can be found under 3D View in the library.

CPU (SSE2) Engine

The PBR Render Node is very heavy and does not work well with the SSE2 CPU engine. Switch to another engine by pressing F9, if node performs extremely bad.

Inputs

  • Material channel inputs
    Multiple material inputs are used to render the material on the geometry:
    • Base Color
    • Normal
    • Emissive
    • Roughness
    • Metallic
    • Specular Level
    • Height
    • Ambient Occlusion
    • Opacity Mask
    • Anisotropy Level
    • Anisotropy Angle
    • Translucency
    • Scattering Distance Scale
  • Lens Dirt Map: Grayscale Input
    Custom map for dirt on lens, that appears when lens flares are visible.
  • Lens Aperture Map: Grayscale Input
    Can be used to override Bokeh, out-of-focus shape. The more contrasted, the more visible it is. Keep in mind only a circle within the texture is sampled, so any shape has to fit within a circle.
  • Background input: Color input
    Custom map used as background when the Background Mode parameter is set to Backgroud Input
  • Environment Map: Color Input
    Enviroment map used to calculate lighting. Must be spherically-mapped and in HDR.
