How do I change an individual object of a collection instance after the Instance on Points node. For example, I'd like the spheres to be higher in that image. How can I use nodes such as Translate Instances but for just one of my collection objects. My instinct would be to assign the index in the selection but I can't figure out how.

My instinct tells me to input something in selection but what?

This answer here only serves to complete the range of possibilities...

If the transformation for a certain object should always be the same, then it is recommended to perform it ideally BEFORE the instantiation.

This way, this operation does not have to be applied to a large number of objects, but happens only once, which can possibly achieve a gain in terms of performance:

PS: And by the way, the correct rotation for your instances is provided directly by the node Distribute Points on Faces.

  • $\begingroup$ This works perfectly. Thanks so much! And how would you go about setting a material for one objetc, and another material for the rest? $\endgroup$

  • $\begingroup$ @Enashka Ideally, with this setup, you should define the materials directly in the objects you instantiate here. $\endgroup$

your instinct is right, you can do it like this:

instead of geometry to instance, you would take your collection ;)

You can use this setup. For example if you have 3 objects as instances, you can test which of the indices is the object you want to translate.
