Frequently Asked Questions

  • Q: Why is there noise/grain/random bright dots in the render? This is not a bug, but an unfortunate effect of the rendering algorithm used in Chunky. Torches and other small light sources cause a very random illumination and it takes a long time to render such light nicely. For more information please read the Path Tracing article. You can disable emitters under the Lighting tab in the Render Controls dialog to remove most of the random bright dots. Note that rendering for a longer time will eventually remove the noise, though it may take a very long time.

  • Q: How long does it take to render an image? There is no exact answer to this question. The main thing that affects render time is your CPU, the size of the image, and the lighting conditions in the scene you are rendering. It can take anywhere from an hour to a couple of days to render a nice image. You can reduce the size of the canvas or disable emitters to speed up the convergence rate. See the Path Tracing article for more details.

  • Q: Is GPU rendering supported? GPU support is not actively being worked on right now. GPU rendering may be added in the future, and some partial progress has been made toward this goal but there are very many hurdles before it is fully supported.
