Guided Ocean - bad render Jan. 22, 2019, 8:34 p.m.

Hello, I'm trying to achieve the effect shown in this video: https://vimeo.com/204806144 [vimeo.com] around the 2 hour mark.

The flip's dynamics seem to behave perfectly as far as I can tell, but when I render I get this strange result.

The only settings I've deviated from the defaults are Ocean Spectrum Resolution Esponent to 10, wavetank Ocean Source Size to 30 12 30, and Particle Separation to 0.06.

Any ideas ?? Thanks.

Finding Normal Distance to Zero-Thickness Nov. 29, 2018, 10:10 p.m.

Hey, I just devised a way to do it in 1 frame, all inside a point wrangle:

Convert your geometry to SDF, vdb from polygons, fill interior. Then in the point wrangle create a for loop, and start sampling the sdf in small steps, like ray marching, starting from each point towards the inside along the normal. The sampled values will be decreasing, starting from 0. So just when they start to increase back, break the loop and store the sampling distance as an attribute.

Edit: You might want to consider using the sdf gradient vector instead of the point normal as your direction vector.

Pretty cool tool, first time using it
