I created clouds using a smoke simuation. So why do they look like ice?

I created clouds by using a smoke simulation. The cloud shapes turned out well but for some reason they look more like ice or some kind of solid object. How do I fix this?*I'm using version 4.0.2 and...

How to keep particles to rotate on a specific axis with Boids physics (on 4.2)

I created a particle system from a plane and replaced the particles with simple cubes. They're set to target a sphere, but I want the cubes to remain fixed on the Z-axis while they move. I can't find...

Domain stays a cube when baking?

Whenever I bake my domain, it stays a cube. It does work when the fluid object is outside of a hollow obstacle I've placed it in. I've recalculated the normals, and tried resizing the domain, but...

Rigid Body Object Jumps back when keyframing "animation" off

I am trying to get a box to float into the air, fly in a direction and then midair activate physics so that it flies off and falls to the ground without me having to animate that. I tried keyframing...

Is it possible to limit the volume of fluid ejected from a mesh? 2.82

I am working with some fluid simulations in 2.82 which I am planning to add to my scene. My goal is to create a fluid sim which looks like rain water flowing off a roof. So far I have a cylinder set up...

Translation and rotation axes not locked

I'm designing a 2D rigid body physics orthographic animation in Blender Game. It's simply a cube falling on and bouncing off a surface (first picture). The camera (in orthographic mode) is pointed...

Make parts of body mesh go through clothing mesh during simulation?

I have a walk cycle set up on my model but when her hands pass her body they also affect the skirt she's wearing which messes the skirt physics up in ways that would be better if I just had her hands...
