Mix Position

Mixes the position “from” and “to”. The animation is set using a factor.

Settings

Selection – geometry selection
Domain type.

  • Points – It is also used for mesh animations.
    Edge
  • Face corner
  • Spline
  • Instance

Factors – For animation offset

From – Usually, the geometry already has an arrangement that needs to be animated, but if necessary, you can set an additional offset from the original.

  • Weight – The weight helps to distribute positions by attributes such as index, noise, etc.
  • Position – Position

To

  • Weight – The weight helps to distribute positions by attributes such as index, noise, etc.
  • Position – position
  • Self Position – Adds its own position to the final value. This option can change the behavior of animations. For example, if you disable it, the mesh will decrease in size.
  • Direction Mode – That is, the end point will be the coordinate that you set
  • Normals Mode – Adds coordinates to the normal. If you split the edges , then each face will move away to the distance that you set. Please note that if the self position is enabled, the face will increase in size.
  • Position Mode – Adds the specified coordinates to the current position. If the native position is enabled, the object will also increase in size.

All of the above is true for meshes. For instances, the behavior will be different. But keep in mind that the self position is a very important parameter.

How to use

1. In Mesh and Direction mode, the mesh disappears, this is because each point takes the final coordinate for all points. That is, all points tend to 0,0,4.
2. Node Make instance, creates instances with the correct position. If you apply a split instance with mesh island, all instances will have a position of 0,0,0
3. When working with instances in the normals mode, the model, although it moves, cannot take on values.
4. The weight can also be negative, which multiplies the values by -1.
