Thank you!!

I can see why you want it. I suspect this is a job for Howie Farkes' UltraScatter as I really don't know how to get the surface position from an object by scripting - I honestly don't know a lot about scripting, I just push what little I do know to the limit. With UltraScatter (the most basic one) you can specify a surface for the items to scatter over. What I don't know from my own experience is whether the surface can be curved as I've only really used it once (to scatter wood carving chips from my wood carving set freebie (https://www.renderosity.com/freestuff/items/97774/wood-chip-carving-set)). From the UltraScatter promo images over at the DAZ shop, the surface can be curved, but I haven't tried it myself. I did get UltraScatter during one of DAZ's many sales and got it for $3.99, which wasn't excessive.

@richardandtracy, all these swarming scripts are my favorite. Would be wonderful if there was a script to attach objects on surface of another object or a prop. I am trying to create an underwater scene, attaching corals to various rocks is far tedious process

I should have realised someone would suggest that! ;)

Thank you for this idea! Hmm. Putting them in a bathtub could have a whole different context.

Thank you all. Just a very strange set of models, which hopefully makes things look just that little bit more realistic. With any luck there will be a use for them.

Thank you so much!

Thank you for making this, and thank you for the interesting bit of Science you included there.

thank you, most kind

Cool prop and a nice physics lesson! Thanks!
