Noise-driven IDistort wrapper with separate U/V controls, blur, mix, and a Check UVs preview for fast organic warps in Nuke.

Quick Distort builds a two-channel noise field, blurs it, and feeds it into IDistort so you can warp an image without wiring the setup by hand. U and V each get their own size and offset; shared lacunarity, gain, and gamma shape both noises together.

Use it when you need heat haze, subtle organic ripple, or a quick break-up pass. UV scale and UV offset set how hard the warp hits. Blur softens the displacement map before it reaches IDistort.

Mix blends the distorted result back over the clean input. Check UVs switches the output to the displacement field so you can judge the noise pattern before committing to the warp.
