Hi Chaps

Hip attached.

If I parent geometry to a null, and then run a DOP particle sim inside that geo, then a strange thing happens; I can't view the scene properly through an animated camera whilst inside the DOP network.

If I dive up one level and view the DOP network, or import the fields into the same geometry context - the positional relationship between a camera object and the geometry is fine. But once inside the DOP network, it shifts……and cannot view the sim in context of the camera.

Even if i select ‘Use Object Transform’ on the POP Object, which has no effect.

Well, if anyone can check out my hip - give me any pointers - that would be most appreciated. I'd liek to run an entire SIM in one geo obj node - not across multiple Obj's

Many Thanks..

Not sure as I can't check your .hip right now but when the viewport is set to ‘show current level only’ - the scene re-centers- try it with ‘show all’

Could be totally off though

Hi , thanks for that, I'm pretty sure that isn't the issue in this case, but I'll re check first thing tomorrow.

Cheers

Unfortunatley that didnt fix it… -

Oh well - weird houdini shit that remains unfathomable……

Does pinning the viewport where it's working properly work for you? You can then dive into the ‘/obj/NEW_EMBERS_SIM/SIM’ and be viewing through the camera.

When you dive into the Dop network its losing the null-parent translation-offset, you can that it's jumping back to 0,0,0 by viewing the simulation afar.

Cheers MartybNz - yeah pinning 1 step up is the only option…annoyingly.

Thanks for taking a look.

It seems DOPs network in a geometry context loses that parent translation offset. So to view everything in context correctly, including DOP's guides etc, you need a seperate DOP object….. can't find way round it.

What a larf. :mrgreen:
