By a comment on one of our videos on YouTube (youtube.com/watch?v=n4AQ3yj3L4w) we stumbled upon a strange behaviour in H19 which took us a few minutes to figure out. Turns out grouping expressions are evaluated slightly differently in Houdini 19.

A single short forum post (sidefx.com/forum/topic/81459) got us on the right track to getting our older setups running correctly in H19. In this very brief video we go over what to keep in mind for correct grouping in H19.

$KarmaXPU Quickstart Pt.4: Excursion - Visualizing Lipid Membranes Download Scene File: https://www.entagma.com/downloads/membrane_lipids_01.zip Notes: - Instead of using the pointVOP/quaternion method to rotate lipids, you could also use the scatter & align method described here: https://youtu.be/tCijuuNIRrs - Im recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have those resources, go wild! Mo had the pleasure of joining Dr. Jeroen Claus of http://www.phospho.co.uk, teaching a visualization workshop to students at university of Maastricht. The topics covered were protein and lipid membrane rendering in Houdini using KarmaXPU. Also check out our Protein rendering in KarmaXPU tutorial here: https://youtu.be/_UTWthfQOmk For more visualization goodness, have a look at our other protein viz tutorial here: https://www.youtube.com/watch?v=M3ldQBVb-ZA 00:00 - Intro 00:32 - Creating Lipid Pair 04:50 - Creating Undulating Points 11:34 - Copying Lipid Pairs Onto Surface 15:37 - Adding Pores 16:25 - Geometry Tweaks 17:09 - Rendering: Building Scene Tree 18:11 - Camera & Light Setup 19:00 - Lipid Tweaks 19:50 - Setting Up Lipid Material 21:37 - Setting Up Pores Material 22:27 - Karma Settings & Light Adjustments 23:15 - Setting Up Depth of Field 24:23 - Final Karma Tweaks & Rendering 25:20 - Infamous Last Words$
