I made a lupine with an array of leaves and 3 different arrays of flowers(for different sizes of the buds). Now I want to make a particle system of this whole lupine. Is there any workaround to do it without connecting all those meshes as I really want to keep it procedural?

enter image description here

----edit----

So sorry I don't know why I typed array instead of particle, I mean I want to use the whole lupine in a PARTICLE system to make a bunch of them. I tried to make an instance of the collection, then put it in a collection then choose it in the particle system, but nothing comes out.

  • $\begingroup$ Make sure the object you are instantiated from (your environment mesh for instance) is not in the same collection as you flower meshes. You don't need to create a "Collection Instance", there is an option in the particle settings where you choose what to render for the particles, you can then use a drop down menu to choose "Collection" $\endgroup$

So I had a quick player around with a scene I just made.

  1. You have to make sure that the object (in my case plane) is in a sperate collection to the the lupin objects.

  2. In the "Particle Properties" tab in the outliner toggle "Advanced" in Hair to get the some more options you might need.

  3. Under the "Render" tab, switch "Render As" to Collection (which I believe you did). In the same options toggle "Whole Collection" in order for it to emit the whole lupin/object as one and not random segments.

  4. In my case (you may not have to) Under the "Rotation" settings I had to change the "Orientation Axis" to Global Y, but have a play around with it, it may be different in your case.

Note You should play around with the "Hair Length" under emission tab in conjuncture with the "Scale" under the "Render" tab in particle properties to get the size you want.

Same Collection

Separate collection
