Watch 3D Artist Saul Espinosa cover some of the new nodes including triPlanar, that accompanied the latest release of Redshift.

Version 2.5 added things like a Redshift RenderView, and MacOS support. It also added a few new nodes that are welcome within production. These include a Color Layer, Color Correct nodes, but also a TriPlanar node. TriPlanar mapping is a nice addition to Redshift, expanding out shader building within the GPU rendering powerhouse.

The Redshift 2.5 included:

• Gloss clamps to combat fireflies
• A better unified sampling noise detector
• Per-object custom shading data and shader switch (for added material variation)
• Automatic memory management
• Various rendering optimizations
• Wireframe shading node
• Proxy compression and optimizations
• Particle tracing primitive
• Triplanar node
• Several interactivity tweaks
• The Redshift RenderView (framebuffer)
• MacOS support
• Katana support

TriPlanar mapping is a technique where you can blend multiple textures within world-space. The advantage is that, in many cases, you can forego UV’s, and texture stretching.

Many render engines will have a triplanar mapping system, while others can be hacked together.

Espinosa also walks through the Color Layer node, and the Color Correct node in Redshift Redshift, citing: “You can apply what you learn in this tutorial to other tutorials like the curvature node and create awesome shading networks.”
