Blender add-on for those who are not able to have the powered-on computer for render for a long time.
For example, the whole image render takes 12 hours. And there is no way to have the computer powered on all the time, but it is possible to power it on for 5 hours with breaks. If you interrupt the standard rendering process to turn off the computer – next time render starts from the beginning, and all progress is lost. PartitionRender add-on allows dividing the image into several blocks – partitions, each of them is rendered separately. Choosing division by X and Y in 2 parts, the image is divided into 4 blocks. Each of them will be rendered about 3 hours that fit in the time to work. Each partition after rendering saves to file. The next time (after rebooting the computer) PartitionRender automatically continues with the partition on which the break occurred. After finishing all partitions renders, partitions automatically compile to the whole image in compositing.
In version 0.0.2 the ability to render only limited partitions range added. That allows rendering different ranges at the same time on different computers. In this case, the final assembly of the whole picture from different ranges performs manually.
Current version: 0.0.5
User Preferences — Add-ons — Install from file — specify downloaded *.zip archive.
Properties window – Render tab – Partition Render
- Set number of partitions by X and Y.
- Press “Start/Continue render” button to start render.
- “Esc” interrupts current partition render.
- You can close Blender/shootdown computer.
- Next Blender runs – press “Start/Continue render” button to continue rendering partition from which you interrupts.
- After finishing all partitions renders they are automatically combined into the whole image in compositing
- Added ability to render a limited partitions range.
- Fixed a bug with an unsaved *.blend-file. If the Blender file is not saved, all temporary files are stored in the system temporary directory.
- Added “Reset” and “Clear” buttons:
- “Reset” – resets current partition to the first.
- “Clear” – reset with all saved partitions deletion.
- Checking “Use Range” checkbox resets partition to the first.
- Compositing nodes for final image combining connected to a separate output Compositing node and removed each time partition render starts. That allows to re-render image without manual editing compositing nodes.
- Added “SaveMultilayer” checkbox. If the checkbox is on – temporary render results saved in OpenEXR Multilayer format including all layers and passes for future use. Only finished image compiles automatically, different passes need to compile manually.
