World-space 3D Blur Filter for Substance Painter

Seamless blur filter that operates using 3D World-space coordinates instead of 2D UV-space, blurring across UV islands and separate objects within the same texture set or UDIM.

• Resolves accurately in the entire range of intensities from very small to very large by choosing an appropriate algorithm for the blur width.
• Designed as a simple straight replacement for the standard blur filter. No complex parameters. No tweaking. No baking needed.
• Supports high resolutions up to 4k.
• Optimized for realtime performance, specially with large blurs.

Compatibility:

• Tested on Substance 3D Painter 2024. 
• Substance Engine version 9 at least is required.
