Important/Additional Notes: 

• Raytraced reflections and shadows are used in the scene.
• There is a bug with GPU light-mass and foliage instances that displays as an error "Lighting needs to be rebuilt" in 4.26
• The rain occlusion mask uses a render target, by default its a static texture, but if you change the layout or want to update the texture, you can enable the render target to output an updated texture. Dust uses an inverted mask, so anywhere that is not wet, will have dust, but it can be painted out with the alpha channel in the vertex colours
