Hi,

I'm trying to build a game with a huge landscape and decided to do a gigantic cylinder mesh (the size on it is 30,1,30, the size of the original brick is 2048,1,2048) to make it as big as possible. However, when I leave the area where the original brick is placed, I fall through (AKA: it can't collide off the brick). Does anyone know of a script or SOMETHING that would make this work?

Ignore above. Unfortunately you cannot make Mesh Collideable. If you just need a cylinder you cancan insert special mesh into the part and change the mesh type to cylinder. You won't fall through but you will interact with it as a block. There is a cylinder shape option on each brick but it has a permanent decal on it :(

You can't set cylinders to be an actual cylinder, unfortunately. If you want big terrain or something, use either roblox's crappy voxel stuff, or get really busy with this thing called dorito/triangle terrain. You'll need Build v4 or a plugin to make it.

Every block has an option to be cylinder shape but has a permanent decal on the side of it. It still acts as a real cylinder though. Guy above is wrong.

Dude, it doesn't. I'm pretty sure I know how the physics engine works. Try taking off your fancy cylinder and rolling it in whatever direction (Hint, linkedrocketlauncher works great for this.) It rolls at times even with the cylinder, but more often it'll roll end over end without physics simulation. That's just how roblox's physics work, bro.

It's because ImplicitNgine (Roblox's specially written physics engine) can only simulate collisions between cuboid shapes and/or spherical shapes. It does simulate a whole lot of collisions at once, however.

This is the perfect situation to take advantage of the wiki advanced circle script.

You can create a collidable cylinder with as little as 3 parts with this script. The idea is create a circle/cylinder the size you need.
It can be invisible and inserted into your cylindermesh. Or just add a few more parts to the circle to smooth it's sides and use the parts instead of a mesh.

Use the circle script in a blank place. Run the script, if you dont like the circle , press reset change the script numbers and run again.

Play with the script changing one number at a time to see what it does. You can make lots of different things with the same script.
