Subject: [PATCH] Adds VFX and optimizes tile map generation

Adds visual effects, including fire and rain, to the scene.
The VFX are implemented using GPUParticles3D nodes.

Optimizes tile map generation by reducing chunk size and tiles
per frame. This improves performance.

Sets the SubViewport to have a transparent background.
