Is there a way to generate custom meshes inside roblox?
I've done a bit of research and all that I could find was about importing already made meshes into roblox, but not a single post saying wether or not you can create your own mesh inside roblox via scripting.
What I mean is wether there is a way to set all vertices and triangles (+UVs) of a mesh similar to what I would usually do in Unity? Or do I need to use Roblox's parts to create a mesh?
I mean studio's terrain generator does just that (and that kind of is what I need it for).
Anyway, thanks in advance for any helpful replys!

No, there is no way to procedurally create a MeshPart or access the vertex data of existing Meshes. Studio's terrain generator does not directly generate mesh geometry either, it fills in a 3D voxel grid with materials and occupancy values, and the actual mesh is generated on the fly at runtime by the game's rendering engine, and with distance-based LoD. Different terrain materials use different algorithms for the geometry the generate.
Using the Union to combine Roblox base parts results in a UnionOperation object which is like a MeshPart, but with a couple of key differences:
Unions always have box-mapped UVs, based on the orientation of the first part selected when unioning 1 or more parts. The only control you have over UV mapping is by orienting the first-selected part relative to the rest of the parts, and this UV mapping only determines the orientation of the box-mapping projection, you have no real control over scale of the UVs themselves (though Texture Instances provide UV offsets and multipliers)
Unions do not have a TextureID property, they can only be texture using built-in materials or by adding Texture and/or Decal Instances as children.
Unions can be undone (usually) because they store metadata about the parts they were constructed from.
The internal meshId of a UnionOperation is not exposed and available for use with SpecialMesh/FileMesh/CharacterMesh instances.
A UnionOperation has the same collision and render fidelity options as an imported MeshPart.
It is not possible to make a custom mesh through roblox by Scripting. What I would suggest is for you to get blender; it is a 3D mesh modeling app that a lot of other roblox users use as well.
If you do decide to get blender, I would suggest that you watch some tutorials on how to use it first; that way you 100% understand the functions of this app, and how you can import your mesh through blender to Roblox.
