Does anyone know some tips and tactics for optimizing your game besides using unions?

I would recommend looking at my comment for this here:

I explain tips to improve game performance at the end of my comment.

Please… Spare me. Using unions will NOT optimize your performance. It is the worst habit to get into and will cause a degrading performance.

"Solid modeling (more commonly referred to as Unions , or a UnionOperation ) is a feature in Roblox Studio that combines or negates two or more Parts to form an object called a Union. – Robox Wiki

To explain, unions are meant for negating and combining multiple parts to create a different shape.
The more complex a union is, the more polygons (or triangles) it has.
The more polygons an object has will affect performance.
Unions also create un-needed poly for simple objects like cubes.

  • Unions were never meant for organizing objects, use grouping and folders for that.
  • Use meshes instead of unions, they allow you to control your poly count and better your game performance.

Is it possible to make meshes without the use of blender?

#4

Unless you are using a different application other than blender, sadly not. You cannot 3d model in roblox studio.

#5

I’m not very good at blender, sadly.

#6

Technically, it is possible to turn Unions into MeshParts in Roblox Studio by exporting them as obj files and uploading them to Roblox.

#7

There is a simple method to make unions less terrible in blender. Export the union, import into blender, run merge by distance on it, export the mesh, import it into studio.

#8

To further explain, unions are basically the meshes of roblox studio. They allow you to create complex objects like you can in blender. However, when creating unions, the game decides your poly count. Unions usually contain more poly than needed. It is better to optimize your complex shapes by yourself.

Thanks for the tips, got anything else in addition to that?

#10

Is there any benefit to doing that?

#11

No, there is not. Unless you change the poly count in blender. The union will have the same amount of poly if you turn it into a mesh.

I am wondering because importing to blender seemed to drop the triangle count dramatically, as compared to studio, without me doing anything. Either the triangle count reporting is wrong or some level of clean up happens as part of the process.
