This is a plugin for Chunky, which harnesses the power of the GPU with OpenCL 1.2+ to accelerate rendering.
Disclaimer: This is not the original; for the original chunky-opencl, go to chunky-opencl. I, myself, do not know much Java, so this was largely coded by AI through a lot of trial and error.
- Full water rendering + settings!
- Glass rendering!
- Emitter Sampling Strategies!
- Sun Sampling Strategies!
- Faster Map Using GPU!
Download the latest plugin release. 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.
Rough performance with a Blackwell RTX 6000 Pro(I got temporary access to one :D) vs 14700k rendering four regions with all emitter sampling at full HD in march 25, 2026:
That's 84k samples per second vs 63 million samples per second, making complex scenes take mere minutes instead of several hours at 750x the speed of a high-end CPU!
(I cut the CPU early as it took forever to render just four samples.)
The map used in the test renders can be found here at Tax' Future City
- Not compatible with the Denoising Plugin.
