How can I make a random multimesh brush that each multimesh part occupies it's own proportion?

Hey guys, I’m making a curve brush which different multimesh parts randomly array alone the curve. The multimeshes are boxes which have all the same width but different length. The brush should work expectedly like this

However when I use multimesh variation function in Brush>Modifiers pallet, it shows a result like this

As you can see, every multimesh part turns into the same lenth but different width.
How can I fix this?

Hello @HanchenYang ,

Unfortunately you cannot use this feature in this manner. The spacing for the meshes is based on the curve stepping, not the size of the mesh. If the bounding box of the mesh section exceeds the curve spacing, it will be scaled down to fit that spacing.

When varying meshes along a curve they will all need to be of similar size. You have a bit more leeway with how “tall” each section is, but extreme differences in size will result in this sort of downscaling.

Thank you for the reply. It made me understand more about the principle of the cuvre brush. I also tried nanomesh but it still can’t appear a satisfying result. So do you have any advice for me in this case?
