Blender Redshift

Redshift Rendering Technologies (www.redshift3d.com) are looking for a good Blender addon programmer to help us integrate the Redshift GPU renderer to Blender! As some of you may know by now, the Redshift team has been working on a Redshift 4 Blender plug-in. This is a plug-in for the Vani. Redshift Normal Mapping and Bump Mapping Intro Tutorial. Like Redshift, Blender offers a number of test projects for free, including the one used for testing here. You can snag the model from this blog post. When testing, you’ll want to make sure that your GPU is actively selected (seen in the shot above). As some of you may know by now, the Redshift team has been working on a Redshift 4 Blender plug-in. This is a plug-in for the Vanilla Blender insta.

Introduction

Sometimes a material uber shader is not enough for effects that ultimately require the overlaying of several materials, like dirt or extra reflection layers for example. To achieve this efficiently with Redshift, you should use the Material Blender shader.

The Material Blender supports up to six 'coat' layers on top a base material shader. Since it is important to preserve energy for 'realistic' materials (meaning, a material cannot reflect more light than it receives), by default layers are not simply added together, they are instead mixed based on the color of each successive layer.

The default mixing rule is such that a layer blend color of 1.0, 1.0, 1.0 (white) results in the layer material color winning, effectively replacing the previous layers, whereas a layer blend color of 0.0, 0.0, 0.0 (black) results in the previous layers winning, with no contribution from the layer material. Layer blend colors in-between black and white result in a blend of the previous layers and the layer material.

Base Material

Color

This input defines the base material shader color. Plug your base shader in here.

Layer 1-6

Material Color

This input defines the layer material shader color that will be tinted by the Blend Color. Plug your other shaders in here.

Blend Color

This is the color tint that is applied to the layer material shader. Note that these values should be between 0.0 and 1.0 and that anything outside of this will be clamped when not in 'additive' mode.

Additive

This mode switches from layer mixing to layer adding. When enabled, the final material result will be each material layer tinted by its blend color and added to the base color.

Note this mode is not energy preserving and should be used with care.

Material Blender Example

Here is a simple scene, demonstrating the blending of two layers on top of a perfectly reflective base layer.

The first image to the left shows just the base color of the sphere, which is an Architectural material shader that fully reflective. You can see the reflection of an HDR environment map in there, along with a white rectangular area light.

The layer color is supplied by an Architectural material shader, with just a brown diffuse lighting component. The blend amount is a texture map that contains a monochrome dirt-map. Since we are not in 'additive' mode, the dirt layer appears as a blended decal.

The third image now demonstrates a decal texture map image, in Layer 2. Again, the layer color is supplied by an Architectural material shader, with its diffuse component driven by the decal image. The blend amount is driven by the alpha channel of the decal texture map.

This shows you the shader graph set-up to generate the final blended sphere.

Concept artist and matte painter Saul Espinosa‘s round-up of the new features in Redshift 3.0 announced during Maxon’s 3D and Motion Design Show last week. The recording of the livestream starts at 03:30.

Maxon has shown sneak peeks of Redshift, its GPU renderer, running under Metal on current Mac hardware, and of Redshift RT, its new real-time hybrid ray tracing/rasterisation render engine.

Both are due in public preview later this year, alongside a new Redshift integration plugin for Blender.

The news was announced during Maxon’s 3D and Motion Design Show, in what would normally have been Siggraph 2020 week, alongside Project: Neutron, Cinema 4D’s new node-based core architecture.

Redshift on Metal: new Mac port of the renderer due with the public beta of macOS 11.0
During the livestream, Maxon previewed the new Metal port of Redshift for users of current Apple hardware.

Announced at Apple’s Worldwide Developer Conference last year, the switch from Nvidia’s CUDA to Apple’s Metal as a GPU computing API will enable Redshift to run properly on current Mac workstations.

Apple no longer supports Nvidia cards, even as eGPUs, and in any case, CUDA no longer supports macOS.

You can see the upcoming Metal port at 04:40 in the video above, running the standard Redshift benchmark scene inside Cinema 4D on an iMac Pro.

According to Maxon, registered Redshift users will be able to test a preview build in the “next couple of weeks”, although the exact timing depends on that of the public beta of macOS 11.0 Big Sur.

The other key Metal-native GPU renderer for Mac users, Otoy’s Octane X, which was also announced at WWDC 2019, has just been released as a free public preview.

Redshift RT: new real-time hybrid render engine due later this year
In addition, Maxon previewed Redshift RT, Redshift’s new real-time render engine.

A hybrid ray tracing/rasterisation engine, it provides near-real-time feedback on complex production scenes, supporting the same materials and lights as the main Redshift renderer.

The demo, which you can see at 05:20 in the video, showed Nvidia’s open-source Attic USD test scene inside Redshift for Maya, running on a Razer gaming laptop with a Nvidia GeForce GTX 2080 Mobile GPU.

Interactive performance in Redshift RT is noticeably better than in Redshift’s existing interactive render preview, and the resulting image is less noisy.

Maxon described RT as generating “pretty clean results almost instantly”, even with full global illumination.

Redshift RT is still “in active development”, with an initial alpha release due later this year.

Redshift for Blender: new Blender integration plugin due in the ‘next few weeks’
Maxon also confirmed that the new Redshift integration plugin for Blender is coming up for release as part of the ongoing series of experimental public builds of Redshift 3.0, the next major version of the software.

Support for Open Shading Language (OSL) is due “in the next few weeks” with “initial Blender support … soon thereafter”.

You can see an alpha build of the Blender plugin – which already supports displacement, instancing, volumes and the Blender hair object – in the video above, recorded by concept artist Saul Espinosa. Download cybernet space saving driver.

Features already available in public builds include support for GPU-accelerated ray tracing via Nvidia’s OptiX 7 platform and support for NVLink. You can find more details in our original story on Redshift 3.0.

Pricing and system requirements
Experimental builds of Redshift 3.0 are available to registered users of the software for Windows, Linux and macOS. Redshift hasn’t yet announced a date for the official release yet.

The current stable release, Redshift 2.6, costs $500 for a node-locked licence; $600 for a floating licence. Integrations are available for 3ds Max 2014+, Cinema 4D R16+, Houdini 16.5+, Katana 2.6v1+ and Maya 2014+.
