If you don't want your actual output to display at all, then create an output with the index -1, and then in your viewer state script you can use


You can take a look at the Otis Muscle and Tissue Configure state to see options for having the alternative output always display, or only display when you're in the viewer state.

hi Liesbeth : thanks for the detailed writeup! Can you explain the difference between muscle ends and tendon mask ? when and where would you use muscle ends Vs Tendon mask ?

I explain it in the first two minutes of this video (the rest of the video is relevant to Vellum only, not to Otis) https://www.youtube.com/watch?v=rmWmYfKfO5U&list=PLXNFA1EysfYlEaZ7w6YbQpWqZY6-l2Onu&index=6 [www.youtube.com]

Alternatively you can watch it here https://www.sidefx.com/tutorials/muscles-masterclass-essentials/ [www.sidefx.com] where it is the sixth video.

I forgot to add that I unlocked the "Otis Muscle and Tissue Configure" node and tweaked the point deform settings for the "Deform to Bones on Reference Frame" option, as they weren't working properly on this large a character. I'll try to come up with a solution for this soon that doesn't change the behaviour for everyone. With the default settings it looks a bit weird on the first frame of the simulation. It's not too bad an issue, as the solver uses the stored tpose to fix it by the second frame, but just be careful to not use the first frame as the "rest" frame for any skin deformations or the like. I also added "tpose" to the output attributes on the "Otis Muscle and Tissue Configure" node so that the tpose can be extracted from the sim.
