How to delete single instances of a Mash network

Hello.


I have built a 4 different Mash networks for a landscape scene. Unfortunately I have deleted a part of the landscape geo and I can't delete the "flying" trees and bushes etc. anymore as there is no geo belo. How can I delete single Mash stand-ins of a big Mash network. (I can't delete the whole network as it is still needed on other parts).

Kind regards

I'm not sure I understand. You want to delete in Maya, before the render starts?

Or you want to delete at render time? In this case, you could use an operator to hide or disable nodes. You just need to know the name of the node you want to disable.

hi Stephen I want to delete only parts of the Mash network based on arnold instances. Normally I would do this with delete in the placer node, but this does not work anymore. is there another way to delete single instances/standins or not needed parts of a Mash network than using the placer node? as there are already thousands of standins in this Mash network of a landscape scene, I dont want to start from scratch by deleting the whole Mash network and redo only the finally visible parts of the entire camera animation.

I'm super late to this thread so not sure if you figured it out, but I've been trying to do the same thing (delete single instances from my mash anim).

If you cache the network and then bake it, the instances become geometry that you can then select and delete.
This does mean that the MASH simulation cant be edited anymore, so it has to be done once you're ready to render. 

caching is done in the attribute editor (tutorial: https://www.youtube.com/watch?v=Jv_rgrcd3C0&t=335s)

and MASH > Utilities > Bake Instancer to objects to switch it to geometry 🙂
