Blender is best known as a popular open source 3D modelling program.
Install the package.
Blender officially supports only the proprietary drivers from both AMD (for GCN cards: AMDGPU; For pre-GCN cards: ATI) and NVIDIA. After installing the proprietary drivers, one can select the graphics card as a compute device under Edit > Preferences... > System.
Professional rendering plugins
Blender is becoming increasingly well known in the professional industry. As such, there are now alternative rendering methods to EEVEE and Cycles, in the form of plugins. This should serve as a list of the major professional rendering plugins that are released or upcoming for Linux.
BlendNet is an open source plugin that allows distributing CPU and GPU renders across multiple machines.
BlendNet natively integrates with major cloud providers like AWS, Azure or GCP, and also supports self-hosting your own render farm.
- Install the AUR package
- Enable the BlendNet plugin in Preferences -> Add-ons -> Enable "Render: BlendNet"
- Follow the instructions on the official BlendNet wiki to configure a render farm on AWS, Azure or GCP.
TheAUR package provides systemd units and configuration to quickly deploy your own CUDA GPU-accelerated Blendnet render farm.
A BlendNet render farm consists of one Manager instance, which distributes tasks to multiple Agent machines. The blender Addon connects to the Manager and the Agents to schedule renders. See the BlendNet wiki for more information on BlendNet architecture.
To start, installAUR on the Manager, Agent and Addon machines, then follow these instructions.
/etc/blendnet/server.crtto all Agent and Addon machines, to
/etc/blendnet/manager.json, adding a manager username and password.
/etc/blendnet/manager.json, adding an agent username and password.
- Start/enable the
/etc/blendnet/agent.json, adding the same agent username and password used in the Manager.
- Start/enable the
Ifis installed, AUR will automatically enable GPU+CPU acceleration: you can check whether GPU acceleration is in use by checking the agent logs:
$ journalctl -xefu blendnet-agent.service
- Enable the BlendNet plugin in Preferences -> Add-ons -> Enable "Render: BlendNet".
- Configure the plugin with the Manager/Agent usernames and passwords.
- Specify the CA certificate located in
- Close Preferences, open the Render tab and switch to the Cycles rendering engine (**NOT** BlendNet!).
- Add all Agents using the
+button in the new "BlendNet Render (local)" Cycles panel.
- Follow the BlendNet rendering instructions.
LuxCoreRender is an open source rendering method that can also make use of OpenCL to render. To make use of it, simply install the ( AUR) package, Then enable the LuxCoreRender addon in the User Preferences box in Blender.
RenderMan is a Linux compatible proprietary rendering plugin that is free for use with blender under a non-commercial license. See the Renderman page for setting it up with blender.
Pro-Render is an open source Blender rendering plugin from AMD that will allow any machine using an OpenCL 1.2 compatible AMD GPU the ability to create realistic GPU renders, allowing for faster work compared to the CPU.
Blend4Web is an open source framework for creating and displaying interactive 3D graphics in web browsers. It contains a Blender add-on to create and export 3D scenes directly into the web. A Blend4Web-specific profile can be activated in the add-on settings. When switching to this profile, the Blender interface changes so that it only reveals settings relevant to Blend4Web. See the documentation on how to install Blend4Web SDK.
Verge3D for Blender is a real-time renderer and a toolkit from the original creators of Blend4Web. Contains Puzzles visual editor to allow creating interactive web applications without coding.
Blender is slow to select objects
When using onboard Intel graphics it may take 5-10 seconds to select an object. Change Selection in File > User Preferences > System to OpenGL Occlusion Queries.
Blender does not show the AMD card as an OpenCL rendering device
Blender only supports the official AMD proprietary drivers for rendering with OpenCL (for now), meaning you will need to install one of the following AMD OpenCL drivers:
- Install AMDGPU#AMDGPU PRO
- Install AUR driver alongside the open source AMDGPU driver
After installation, the AMD GPU should now appear as a selectable device under File > User Preferences > System > Compute Device.
If fonts look small or blurry, their size can be increased (by a point or two) in User Preferences > Themes > Text Style. Selecting a bold font family as Interface Font in User Preferences > Themes > System can also greatly decrease blurriness.
