Spline based mesh and custom scale at each spline points

[d0minas]

Hi,

I’m working on some tool that is based on the flat spline meshes but requires different scale at each spline points. The easiest example would be a river / road spline but you want the width to be custom at each spline points. Scalling at the spline point using scale gizmo does seem to be blocked by default - applying the scale works on the forward axis only but it does change the length of tangents, does not affect the spline scale values. I’m able to apply different scale at each spline points manually (from the details panel) but then the mesh doesn’t seem to be affected while the spline visualization shows that properly:

Is it possible to apply a different scale at each of the spline points so that it will automatically rescale the mesh? The assumption is that the scale between spline points is linear but each of the spline points can have a different scale.
Also I would like to use the scale gizmo for that purpose.

Thanks

Try:

Needs to be added to the update where apply location & tangents to the Spline Mesh Comps. Imagel lifted from:

Collision On Splne

Post script, no one can guess what’s up. But, the standard approach would be: run Construction Script iterate over spline points add Spline Mesh Components - you do not need overly complex meshes, consider performance. A low-poly cylinder with 4-5 rings should be fine. Or a box with a some subdivision. apply spline location and tangents to the SMCs set Start Scale and End Scale of the SMCs - at no point should you be scaling the actual mesh yourself. No clue how the rest of your script looks …

I had these. The outcome I initially posted is with these already.

BTW, I’m on 5.2.1 if that matters.

Does it work for you if you manipulate the spline point’s X scale?

[d0minas]

Ha! It does… Do you know why?

And also - it does when manually changing it. Is there a way to do it via the scale gizmo? (neither of the axes works)
