This course is for people new to crowds. It is a beginner level class that dives deep and offers a comprehensive look at typical crowd workflows. Learn how to work with in-place animation clips and locomotion clips to feed your crowd system then explore transitions, interoperability, triggers and techniques for art directing your crowds using pre\post sim adjustments. In the end, you will have a strong understanding of the crowd tools in Houdini and will be able to successfully incorporate them into your projects.
These video tutorials are made up of smaller chapters covering a range of different topics. The chapters are highlighted with timecodes.

Awsome,
to bad i can`t figure out why my usd files only capture the first frame of the agent standing stil.
its movien in the sop create and Its only when i render them out as with the USD rop that they stand stil.

im on 19.5 it also happens in the file provided in the project files.

@NicTanghe I noticed one issue in the provided project files, probably due to changes with newer Houdini versions. Toggle on "Cook Frames as Single Work Item" on the ROP USD Output TOP (for example /stage/topnet1/agent_walk in 9.2_blendshapes_simple_v1.hip). This will ensure all frames of animation go into a single USD file.

Thank you that is indeed what sulves the problem.
Now i run into the problem that turning on convert to in place animation throws me the error does not exist.
Perhaps this is not the best place to discuss such issues as we are unable to edit comments.
