Scaling Objects with Materials and Niagara in Unreal 5

This week we have a look at how to use the distance between an object and the camera to change the scale - shrinking things close up and making things grow in the distance.

This worked perfectly. Well done and well explained.

Awesome Video! But I do have a question. What if you want the particles to reduce in size as the camera gets further away? Also is there a way to reduce spawn rate as the camera gets further away?

[@tharlevfx]

@@haydenbailey2184 same logic - just do a distance check and then scale the particles down at far distance

Really helpful video, thank you!

Hello Im trying to make a material that fully disapears when you get close and enlarges when you walk away and then fully disapears after a certain distance however im having troubles tweaking this to work my material is also translucent and I would like it to be a sprite too if you could help that would be great I can pay if needed

Have you taken my materials courses on Gumroad or udemy? I cover all that and more in detail.

[@duckonquacks1436]

Is there a way to scale the whole system rather than just the particles?

[@tharlevfx]

@@duckonquacks1436 yup - do the distance calculation in niagara and then use that to scale the spawn value and size of the particles

[@warehousevirtuals]

You are awesome btw

For some reason, no matter what I try, my scaling down particles when zooming in, just isn't working. I am working on Unreal 5.2 but I feel like it should still work.

Version shouldn’t matter - maybe just double check all your logic and values, it’s so easy to make a simple mistake in the scratch pad
