I'm loving the update! Thanks so much for working on this more!! Multiple instances of fog allow you to have a "God rays" effect, which is next-level, imo.

I do have a bug report - when I load a scene with fog boxes, the fog boxes all seem to have reverted to their original/default sizes. If I open the plugin after loading the scene, the size sliders are at the correct values; changing them will cause that parameter to correct itself, the boxes "pop back" to the set size.

attached pics: Original, with correct boxes; and after loading, with small fog boxes that don't reach to the ground.

I want to add that I am not sure how "Masking" works - I tried loading a random black-and-white PNG file and it appeared to simply turn off the fog box. The "Reload" and "Remove" buttons didn't behave as expected, either - "Reload" turned the fog box back on (with no apparent masking) and "Remove" turned it off again. Hoping we can get some clarity on this functionality at some point!! Would be really cool, if it is what I think it is.

inside fog, and a major performance boost

View attachment 613903

What's new:

1. Inside fog for Box / Sphere Fog. Step into the volume and still see the fog. One toggle (on by default).

2. (Box / Sphere Fog) Much better performance with lighting enabled. Point and spot light scenes stay smoother when Enable Lighting is on.

3. Lighting is easier to balance. Fine-tune for looks or frame rate as needed.

Here, the beam cutting has been greatly improved. For other new features, please refer to the last update.

New Features:

2. Align to view or pick a surface: in pick mode, click any scene object and the plane snaps onto the surface and matches its normal (desktop).

3. Fine-tune placement: push or pull along the normal, use X/Y/Z offsets, and adjust rotation and...

Experience optimization, bug fixing

View attachment 639521

Highlights:
1. Fog Color sticks when lighting is on. Extra lights no longer wash the volume to pure lamp color.
2. The Mask section now has a title and a short note. You can see how the grayscale map thins density.
3. Every section title has a short hint, with taller text so Chinese and English aren’t clipped.
4. Three near-no-op controls are gone: Ambient Strength, Light Absorption, Add Pass Shadows. Default look is unchanged; the panel is cleaner.
