The Distributed Rendering Bucket Render Element renders an image with each bucket shown in a different color, and a short text on each bucket naming the machine that rendered it. A bucket is a region of an image that is being rendered. The render setup must be set to use the Bucket image sampler, which divides the rendering process into render buckets. This render element is useful for assessing machine performance or for troubleshooting a distributed rendering process.
