The video shows you exactly how it's done.

I use this in almost every project and it's really useful.

I think it is worth the price as it is now, but it still needs more shapes. For example, I would really appreciate seeing a tetrahedron with 3 right triangles and 1 equilateral triangle. Anyway, great work!

Looking for a mesh set that includes thin two-sided cylinders, domes, pyramids, etc for use as FX material layers? This is the set you want.

This is a great package for when you have to create some sort of object or building, these objects should really come with the standard unity package. Definitly recommended

The objects are grouped into 3 'blend shape' groups so you if you need to create separate avatars for each object you might have issues. You will have to create your own prefabs by dragging each object out from the main prefab. There's no colliders on any objects and each is rotated -90 on the x axis. A few objects ares are not aligned with their transform axis. So there's a little work involved to get these ready for actual use.

Have only used a small portion of these shapes that are on offer but I must say very handy and some of the shapes already have a home in one of my projects. How about hollow spheres and drums?Great value for money

While this certainly has a bunch of shapes, this thing does not make it easy to use them right off the bat. To be honest, the only reason I'm giving this at least 3 stars is because it comes with a neat script to combine objects together. (even though I think it says you can find it online somewhere and I had to look through the source to figure out why things weren't working.) Thing comes with 3.. prefabs? Each containing a bunch of objects. So before you can use any of them, you'll have to drag the prefab out, and then make a new prefab out of each of the objects given. You "could" use their included script to automatically break it up into separate objects, BUT, all the names become generic (ie. obj_1_5), but the worst part, the exported meshes are unusable, as their origin ends up being wayyyy too far away. But back to dragging the objects 1 by 1, it certainly works well enough, and the origins are at the correct position but... some shapes are oriented at an odd angle. For example the halfsphere is tilted at like a 35-ish degree angle along two axis.. So I had to manually re-adjust that. Maybe I just didn't do something right, but I'm pretty sure I read the single sentence of instructions attached, that was relevant. ANYWAY, even thought I had to do a bunch of work to get these primitives to work, in the end I'm happy-ish. Just not 5$ happy.. Maybe happy enough to have spent $2 and left a $3 dollar tip for the inclusion of that mesh combining/editing script

The assets are good, but it's pretty shocking that the different objects are forced together in one big mesh

For the price you get lots of primitives. No problem at all. It does what it says. It is, what is pictured.
