Before I want to write down my wishes I have to say that I love sideFx and Houdini over all other major 3d packages. I am quite sure sidefx is already working on it but Mantra GPU and more artistic friendly tools and gadgets for animating characters would be great (for example improved viewport performance). In case Houdini will push mashine learning I am interested in solutions to upres simulations.
I am not sure if there is a demand for it yet but they can add 3 more buttons for the individual extraction of the Pre-Transform. I am no expert in rigging but it could improve the usuability to set up rigs. - Extract the Pre-transform for the position - Extract the Pre-transform for the rotation - Extract the Pre-transform for the scale My second wish is to get improved cloth tools.
