I have another question :D

So, currently I am planning to create a short film in Blender for my intermediate project at uni. I am trying a few things out right now to tackle probable future problems already since my project is not green lit by prof. yet.

I have a few very low poly buildings and want to create a city line for a background shot later. I use a Particle system with children. The problem I have is that all the buildings intersect and overlap. Looking for a solution, youtube and blendernation were not helpful at all unfortunately.

Do you have any idea how to solve this?

What I am aiming for enter image description here enter image description here

Btw. if you have any tips or ideas how I could achieve my aim better and nicer and with more fidelity, I would highly appreciate it.


I solved my problem with Blue Noise Addon from Github!

I'm not sure there's a way to avoid particle overlapping (except maybe with the help of this tuto?), but you can:

  • Create several buildings, texture them. Put them into a collection called Buildings:

enter image description here

  • Create a plane (let's call it Generator) and give it a Particle System > Hair, activate the Advanced option, choose the collection you've created as particle, give it an Emission > Number of 20:

enter image description here

  • In the Modifier panel > Particle Settings, click on Convert. It will generate instances, reorganize them so that they don't overlap, select all, make the objects single users and join them with J to create an object:

enter image description here

  • Come back to your Generator plane, generate a new combination, vary the Emission > Seed and the Render > Use Count settings so that it differs from the previous combination. Do the same as before in order to create a second object. Do it again several times, put all these objects in a collection called Master.

  • Create a new plane, subdivide it for example 10 times, give it a Particle > Hair, activate the Advanced option, choose Master as its particle, give it an Emission > Number as high as you have faces on this plane. In Emission > Source, deactivate Random Order, choose Particles/Face = 1.

enter image description here

  • $\begingroup$ Hey thanks for the Idea, that would work but the buildings look to unique in position because they were joined before. Useful for other things though, I will save that! Thank you! I solved my problem with "blue noise" addon from Github! $\endgroup$
