4.26 Particles Scale Mesh Size modules bug?

as 4.26 when I use the Scale Mesh Size modules with a Mesh Renderer as a target render, the particles meshes disappear entirely.
It works fine in 4.25.4 so I don’t know if something has changed with the update?


Yes, the same.

I found solution:

  1. Press on Niagara node
  2. Find Mesh Attributes
  3. Set mesh scale to Uniform

Yep it works! Good catch :cool:


Thanks! Had this problem on 4.26.1

Awesome! Great find!

Where is Niagara node?

In your Niagara emitter, it’s the whole stack. Mine, for example, says hanging particles.

Click on the whole stack, and then in the selection screen search for Mesh Attributes. Screenshot attached as it took me a second too. In my screenshot - Blick on and select one (should surround it with a yellow line), then go to 2) and type it in, and then see (3) where it is.


Thanks!!! I’ve looked around for days!

Thank you very much for this. I want to say that this also happens in Unreal 5 and this solved it as well.
