OpenCL Plugin

This is a plugin for Chunky which harnesses the power of the GPU with OpenCL 1.2+ to accelerate rendering.

This is currently a work in progress and does not support many features. The core renderer itself is still under development so render results may change drastically between versions.

Installation

Note: This requires the 2.5.0 snapshots.

Download the latest plugin release and extract it. In the Chunky Launcher, expand Advanced Settings and click on Manage plugins. In the Plugin Manager window click on Add and select the .jar file in the extracted zip file. Click on Save and start Chunky as usual.

Select ChunkyCL as your renderer for the scene in the Advanced tab.

Performance

Rough performance with a RTX 2070 is around 400 times that of the traditional CPU renderer as of 2022-01-27.

Some settings have been added to improve render performance.

  • Indoor scenes should disable sunlight under Lighting
  • Draw depth may be adjusted under Advanced
  • Draw entities may be unchecked under Advanced
  • OpenCL Device selector under Advanced

Compatibility

  • Not compatible with the Denoising Plugin.

Development

This project is setup to work with IntelliJ and CLion. The base directory is intended to be opened in IntelliJ and the src/main/opencl directory in CLion.

For hot reloading, add -DchunkyClHotReload="<src/main/opencl directory>" as a JVM option.
