Hello
there are many examples on this forum. I encourage you to search with Dendro Keyword. There are many scripts available, I have done some
But for sure there are some tricks.
Never provide non flattened data to Dendro! If there are branches there will a volume per branch.
Take care of the voxel size = radius / (value > 2)
I encourage you not to use sliders on the settings. For low number of calculation it is OK but could lead to lag for high number of points.
I also no more use the curve component (there are some others trick to use it) and I prefer to divide all curve to points (distance << radius)
