Realistic Tornado Disasters

Tornado visuals

• Tornadoes now render in front of storm clouds so you can see the funnel against them. Increased opacity by 4x.
• Removed the circular gap that used to clear clouds around a tornado.
• Tornadoes now stop at the cloud base, around Y=180, with a fade across the top 15% of the funnel. They no longer stick out above the clouds.

Rope tornadoes (F1-F2)

• The whole funnel now bends together from the ground to the clouds.
• Reduced the spin speed multiplier from 4.5x to 1.2x.
• Kept the funnel thin all the way up and made the upper section use the same texture and appearance as the rest.
• Added S-shaped bends and ripples using several wave frequencies.

Wedge tornadoes (F3-F5)

• Fixed the funnel's widening so it expands up to its original height, then tapers slightly toward the clouds. This fixes the oversized cone shape.

Fixes

• Tornadoes no longer render below ground.
• Added the missing PI constant that caused a shader compilation error.
• Reduced the render box height to match the cloud layer.
