I've had one reject for taking to long to render |
Carl, Vlad posted this which might help.....
1. SLOWEST: Image-based components (Blur, Motion Blur, Sharpen and High Pass) with any slow component (like Worley-based noise) as a source.
2. SLOW: Worley-based noises (any Noise except Perlin, which is very fast).
3. SLOW: Image-based components (see above) in general, because they need to prepare a source bitmap before rendering themselves.
4. CAN BE SLOW: Refraction, especially with a slow component as a source. Refraction takes 3 samples of the source input.
5. CAN BE SLOW: Any Noise (or any component based on Noise such as Noise Gradient, Noise Distortion or Noise Curve) with high Detail and Roughness (they are interdependent) especially with a custom curve as a profile.
6. CAN BE SLOW: Any Noise with a custom curve as a profile -- the curve is sampled once for each noise octave (for Details = 10 you have 10 samples of the curve per one noise sample).
5. CAN BE SLOW IN CERTAIN CASES: Any component that generates edges for anti-aliasing (Patterns, Worley noises, some of the adjustments). But since anti-aliasing is done in a separate pass, that shouldn't impact speed too much.
6. FAST: Patterns, Channels, Adjustments, Gradients (except for Noise gradient).
7. ULTRA-FAST: Externals (Image and Selection), Checker, Switch, Blend, Offset.
