Particles to Spline
Making particle Trail
each particle from different emitter(point) should have attributes.
Particles are better to emit every frame with $NPT
make group by partition and the attribute
- partition Rule = particles`point(opinputpath(".",0),$PT,"parentId",0)
add add
- check Delete Geometry but keep points
- Polygons by Group = particles*, add = Each Group Separately
add Resample if you need.
Fake Motion Bulr
needs to cache out the particle simulation at first.
add trail
add add
- check Delete Geometry but keep points
- Polygons by attribute = id
If you want to edit length, use resample
- check Resample by polygon edge
- method = Even Length Segments
- uncheck Maximum Segment Length
- check maximum Segments
- set 2 (if you want cut the line half)
add UVTexture
- Texture Type = Rows and Columns
- Apply to Point Texture
add Delete to delete back point
- $MAPU == 1
If you have Camera move, add inverted Camera Transform before and camera transform after this.
