Render Preview


The render preview displays an interactive 3D preview of the loaded chunks. While a render is in progress, it will display the live progress of the render.

Figure 3.2.6.1: The render preview

Chunky will automatically switch to the render preview once selected chunks are loaded or a different scene is loaded. If a scene.dump file (render progress) has been saved for the loaded scene, then the render preview will display the state of the render at the point where it was saved. If no scene.dump file exists for that scene, then Chunky will generate a preview of the loaded chunks based on the camera settings, with crosshairs in the center for targeting.

Figure 3.2.6.2 shows the render preview displaying live render progress.

The four lines in the box provide the following information:

  1. Distance to the currently-targeted object in meters (blocks).

  2. Block ID and blockstate of the currently-targeted block, if any (does not include entities).

  3. Location of the camera in Minecraft coordinates.

  4. Direction the camera is facing.
