Week 7
July 8 — July 12
I had been experimenting and by the end of this week, I eventually had a working pipeline of rendering an image into three pieces then merging them together into a complete image. The whole pipeline looks like this:
- Disable compositing
- Figure out the borders (with 4 pixels of overscan) and do border rendering to get the three pieces
- Find out the RenderLayers node in the node tree
- Construct a set of nodes to merge the three pieces into one
- Reconstruct the original node tree by replacing the RenderLayers node with the newly created set of nodes
- Final compositing
The result looks promising:
There are still quite a few questions I need to answer before this thing could be called “production-level”:
- Why do we have discrepancies when the three pieces are rendered with compositing enabled?
- What additional data we need to make sure denoising works?
- What are some Cycles features we are theoretically unable to support at the moment?
While figuring out the answers to these questions, I will also be landing my previous PR and open a new one this week.
