Why we like it

Splitexr earns its place in the superhive library for handling multichannel EXR splitting and CryptoMatte node setup inside Blender, with documentation included.

What is Splitexr?

Splitexr is an add-on for Blender, developed by VFX Grace, that works with multichannel EXR images. It splits those images and removes unused channels, keeping the process inside Blender.

The add-on also adds and connects CryptoMatte nodes, covering three modes: material, object and asset. When Splitexr splits a multi-channel file and the file output node does not output in OpenEXR MultiLayer format, it automatically adds folder hierarchy paths, so the output pathing is handled as part of the split. Documentation is included, and a demo video is available.

Splitexr is listed for Blender 2.8 and ships under the GPL license. It appears in the superhive library alongside other Blender add-ons. For current compatibility and licensing details, check the developer's page before downloading.

Who is Splitexr best for?

Splitexr is best for blender artists who work with multichannel EXR images and need to split channels or set up CryptoMatte nodes across material, object and asset modes.

How much does Splitexr cost?

Splitexr is completely free to download and use.

Frequently asked questions

Which Blender version does Splitexr support?

Splitexr is listed for Blender 2.8 and is distributed under the GPL license. If you run a newer release of Blender, check the developer's page to confirm whether it works with your version before relying on it. Because it is listed only for Blender 2.8, testing it against your own setup is the safest way to confirm behaviour on later releases.

Is Splitexr free to use?

Splitexr is listed as free in this catalog, and it ships under the GPL license. Pricing and licensing terms can change over time, so check the developer's page for the current details before you download. Reviewing the GPL terms is worth doing if you plan to modify or redistribute the add-on within your own Blender projects, since that license governs those permissions and how the code can be reused.

Does Splitexr set up CryptoMatte nodes automatically?

Splitexr adds and connects CryptoMatte nodes for you, and it covers three modes: material, object and asset. That means you can get CryptoMatte set up in your Blender compositing across those three modes without wiring the nodes manually. Alongside this, the add-on splits multichannel EXR images and removes unused channels, so CryptoMatte handling sits within its broader EXR workflow. A demo video is available if you want to see more before installing.

What does Splitexr do when the file output node is not in OpenEXR MultiLayer format?

Splitexr automatically adds folder hierarchy paths when it splits a multi-channel file and the file output node does not output in OpenEXR MultiLayer format. In practice, that means the add-on manages the output path structure in this specific case rather than leaving it to you. This behaviour is part of how Splitexr splits multichannel EXR images and removes unused channels, so the pathing fits into that same splitting step within Blender.
