This is another of those “What the….” issues with Houdini.
I have a POP net. It takes about 5 minutes to cook. It starts at 0 and has 3 second pre-roll.
I bring that POP into Geometry using POP SOP and set start time to 0 and pre-roll to 3. And NOTHING. 30 minutes later, it still reports ‘Birthing Particles’ its not frozen, as I can interrupt it. But it never gets beyond Birthing particles stage. This kind of disparities just make no sence to me.
How can a popnet that has cook time of 5 minutes take forever to birth in POP SOP?
Additional annoyance. It just seems to me that Houdini overdoes on cooking. I understand that when I am in popnet and go to start of simulation, it must re-cook. But why re-cook if there are no changes, even when Cooking is set to Changes.
Still at start, I drop down to SOPs and bring in a popnet. Now it re-cooks again. WHY? Its already cooked. Such a waste of time. After cooking the POP SOP in SOP I go to Objects. Still at start time, and it re-cooks again!
With each cook taking five minutes or more, this ridiculous.
Now I though that once the popnet is done, I can turn off the cooking and set it to NEver. Then I can just go to ROP and render. No can do good budy. Without re-cooking first, particles do not render.
This is very time inefficcient to say the least. What are some of the short cuts. It would be nice that after cooking the particles, Houdini would just bake them, so user can scrub back and forth in Objects and SOPs without wasting time.
