Name | Type | Default | Description |
|---|---|---|---|
| curve:minwidth | float | 0 | Minimum curve width in raster coordinates. Value range: 0 or more. |
| dice:offscreenmultiplier | float | 1 | Dicing rate multiplier for objects outside the viewing frustum. Value range: 0 or more. |
| dice:triangle | string | trim | The method used for dicing "triangles". The default method "trim" renders triangles by trimming a quad. The "blp" method renders a quad with two points being coincident. Supported values: trim, blp. |
| stitch:refwarning | int | 1 | Enable stitch warnings. Value range: true/false. |

|---|---|---|---|
| bucket:order | string | horizontal | Render bucket order. Supported values: horizontal, vertical, zigzag-x, zigzag-y, spacefill, random, spiral, circle. |
| bucket:orderorigin | int[2] | -1 -1 | First bucket for "spiral" and "circle" order. Image center is [-1 -1]. |
| checkpoint:asfinal | int | 0 | When enabled, this keeps the extra channels and the checkpoint tag when writing the final image for the render. The final image will be identical to any other checkpoint, rather than a slimmed down image. This means that once your image has reached the quality you've set and it completes, it can always be restarted by the user later. Value range: true/false. |
| checkpoint:command | string | empty | System command to be called after checkpoint. If system calls are enabled, then after a checkpoint has been written, the specified command will be called. This is synchronous; the rendering threads are quiescent while this runs and will not resume again until the process returns, avoiding possible race conditions if the command takes a token %i will be replaced with the current increment, zero-padded to 5 digits. The token %e will be replaced with the elapsed time in seconds, zero-padded to 6 digits. The token %r will be replaced with the reason for this update to the checkpoint files (either completely `finished`, `exiting` early due to exitat option, or a normal `checkpoint`). Literal % characters may be inserted with %%. |
| checkpoint:exitat | string | empty | How long render should run before writing a final checkpoint and terminating. Value can also be a string such as "10m" or "0.5h". Set to 0 or empty to disable. |
| checkpoint:interval | string | empty | Write framebuffers to disk every N progressive steps. If value is positive the units will be interpreted as seconds. If value is negative its units will be interpreted as increments. Value can also be a string such as "10m" or "0.5h". Setting option to 0 or empty will disable checkpoints. |
| checkpoint:keepfiles | int | 0 | If set to true then prman will write to a new, numbered image for each checkpoint. Note: This will disable the final write of a checkpoint file which means the render cannot be recovered using the 'recover' option. Value range: true/false. |
| Ri:CropWindow | float[4] | 0 1 0 1 | Crop window [left right top bottom] in NDC space. |
| Ri:FormatPixelAspectRatio | float | 1 | Output image pixel aspect ratio. Value range: 0 to 1. |
| Ri:FormatResolution | int[2] | 640 480 | Output image resolution. |
| Ri:FrameAspectRatio | float | -1 | Output image aspect ratio. |
| Ri:ScreenWindow | float[4] | 0 0 0 0 | Screen window [left right top bottom] in screen space. |
