Hair not animating when using guidegroom nodes April 23, 2026, 3:30 p.m.

Is this method still working in Houdini 21?

Currently attempting a groom and after plugging my guide groom (fresh scene) into a guide deform (groom 1st input, static model 2nd input, animation 3rd input) the guides stayed in place and didn’t move with the animation. Does anyone know why this might be and if there’s a fix?

It should still work. Is this at the Object level or in SOPs? Are there any errors or warnings? If you do a blendshape between your static model and your animation does it work without scrambling the points? Have you tried a guide skin attribute lookup on your guides before the guide deform with the static skin as the second input?

That's because you are in Fascia mode instead of full Tissue mode.

The "deform_skin" subnet is designed to be used with the full Tissue mode, so to do this, set the "switch_sim_tissue" input to "1".

If you want to deform the skin with the fascia only (not really recommended for Otto, but might make sense for very lean characters that don't have any body fat) then you can change the group in the blast node to "tissue_core_surface".
