Bake All Dynamics for Hair Particle Systems

For reasons unknown, you cannot bake multiple hair particle systems with dynamics at the same time. Supposedly it's not a bug, and it was coded that way. I think it's nonsense. The button "Bake All Dynamics" is literally there, and it does nothing.

I'm here finally learning particle hair because hair curves are VERY unoptimized.

For 10 particle systems on the same object, I created scene drivers to tick one box which will tick 10 other boxes one for each particle system like Enable Hair Dynamics, because I cannot select multiple and alt + click the box to enable all of them.

No problem. Although after spending one hour to set everything up, I could not believe that Bake All Dynamics doesn't work for hair particles. On top of all that, I have to INDIVIDUALLY click Bake on each one of them, even though they all are calculated simultaneously !

How has this been a problem for years, and with all the amazing improvements in Blender, something like this still gets ignored ???

Please can any developer look at this

I have discovered that if rendering an animation with only one computer, you dont have to bake. Actually make sure there is no cache for any of the hair systems and Blender will calculate the dynamics during the rendering. This has been working for me in 4.1. However, when rendering with multiple computers it is necessary to bake all the particle systems separately and then assign the external cache to wherever they were baked.

Well, if it is the intended behavior with the current implementation, it is indeed not a bug but a limitation due to the implementation.

But yeah, definitely not ideal. I hope it's one of the things that will go away with the current works on simulation nodes.

Thank you. I've wasted a whole day on that. Now I can go forward. Hopefully that'll get removed or fixed.

Take care Karen
