OpenCL Preview is just a gray screen in new Chunky snapshots

[KhazP]

Hellos,

I've been trying out the OpenCL plugin with the latest Chunky 2.5.0 snapshot (chunky-core-2.5.0-SNAPSHOT.381.gf277ba6), and the preview renderer just shows a solid gray/black (depending on what sky I choose) screen instead of the scene. The main path tracer might have issues too, but the preview is definitely broken.

I did some basic troubleshooting by simplifying the OpenCL code that runs on the GPU with Github Copilot:

1. Made it output solid red: Worked! The screen turned red. So the basic OpenCL stuff seems okay.
2. Made it output blue if a ray missed geometry, green if it hit: Got solid blue. Looks like the rays aren't hitting anything.
3. Made it color the screen based on the ray directions: Got solid pinkish. This seems weird, like all the rays are pointing the wrong way.
4. Made it color the screen based on the camera's orientation data: Got solid yellow. This also seems wrong, suggesting the camera orientation data being sent to the GPU is messed up in the new Chunky version.

So, it really looks like the main problem is that the plugin isn't getting the correct camera orientation from Chunky 2.5.0, causing the rays to go in the wrong direction and miss the scene entirely.

Also, a separate bug: While testing, I sometimes got this crash related to blockMapping being null when the scene resets:

java.lang.NullPointerException: Cannot read the array length because "blockMapping" is null
    at dev.thatredox.chunkynative.opencl.renderer.ClSceneLoader.lambda$loadOctree$3(ClSceneLoader.java:69)
    ... (stack trace) ...
    at dev.thatredox.chunkynative.opencl.renderer.OpenClPreviewRenderer.sceneReset(OpenClPreviewRenderer.java:121)

Maybe something changed in how the camera orientation is stored or accessed in the new snapshots, or I changed something in the code while trying to debug? And the blockMapping thing seems like a separate issue during scene loading.

Hope this helps track down the problem!

I have exactly the same issue, but noticed that entities render, blocks do not.
