RBD Material Fracture Wood Issue Jan. 27, 2021, 1:19 p.m.

Fwiw, I was having the same problem and Sean's suggestion of Detail -> detriangulate -> only unchanged polys worked a treat.

Merging VDBs into a new VDB Oct. 5, 2019, 6:05 p.m.

Finally it seems vdb combine actually does what it says on the tin, as of 17.5, with the ‘Flatten all A’ option.

This is how this node should have worked from the start and was one of those things where I couldn't understand why for years it was so convoluted to flatten x number of vdbs!

Ocean Spectrum foam and downsampling Oct. 5, 2019, 6:42 a.m.

Hello all,

I'm using 2 merged ocean spectra to generate a large ocean, and then plugging it into the foam sop. The 2 ocean spectra represent low freq and high freq waves, with the high freq spectra being very high res (12 res. exponent) and the low freq being only 8/9. This makes the foam generation very slow. I'm looking at using the downsample parameter to speed this up, but I noticed that the ocean evaluate has a ‘max resolution’ parm also, so instead of globally downsampling both spectra, you can just set a clamp on the res.

However, I notice that unlike the downsample parm, the max resolution parm is not promoted on the ocean foam sop from the ocean evaluate that is inside. I am wondering if there is any particular reason this is not exposed? To my mind it seems a better option than globally downsampling both spectra (as with a downsample of 2, my low freq spectra would then go from 8 to 6 - too low, as well as the high freq spectrum going from 12 to 10)?

Any advice from people in the know would be awesome.
