How to combine individual 3D tiles to make them look like one

Unity Engine

This must be simpler than I’m imagining but let’s say we have a 3D piece of ground as a 1x1 square. I have some script that allows me to play that piece of ground into a grid, now let’s say I put another 1x1 square orthogonal to it, how would I then combine them to look like a single piece rather than two individual pieces? Is the mesh actually being combined? Swapping out for a particular piece? Using edge meshes and center meshes?

Any advice to get me going would be great, and assuming the same would apply for bigger ground sections as well, say 4x4.

To ‘Look’ like they’re combined? Or… actually combine them?

If they are perfect proportions, and placed on a grid correctly, they shuold appear solid. But, to actually combine them together, well, theres tonnes of free tools that can do that for you.

Look up Mesh Combine.

Thanks for the reply, I guess I mean more to make them look combined. To give a better example of the effect I want to achieve, check out

Assets like those you are viewing, are created with a perfect tile set math in mind. So, when placed on a grid of the proper size (based on the art tile size) , they will jsut fit together. Its pretty easy to make some basic tiles and test it out.

Right I get that part, but how do you visually represent them as a single entity?

You position them correctly. That’s all there is to it.
