A shape with Particle effects changes size after being temporarily masked in the Outliner First I created a circle and applied a Particle System to create pine cone style vegetation.

Then I masked the Circle in the Outliner (using the Eye icon), to allow Blender to go faster, and created a little house with a smokey chimney (smoke made with Metaballs) to place in the scene. I converted the Metaballs to Mesh and applied a decimate to it.

Only, when I clicked on the Circle's Eye icon again in the outliner, the Circle was now huge and had undergone a transformation I didn't expect.


Looks small in material view, huge in rendered view. But it used to look small in rendered view too in the beginning.

The only modifier is the one on the smoke (displace), so I thought that was accidentally applied to the Circle, but I can't see this modifier listed when I select the Circle.

What happened to this Object, and how do I make it look "normal" again in Rendered view?
Your particles are huge.



Try using something like .01 for the root size (this value is in BU, at least when Scaling is set to 1).
