For one, unions don’t remove any of the lag that importing a mesh from blender removes. (Let’s say you are making a flower pot, and by unions it’s 70 parts. 70 parts is laggy but you can make it in blender for only one part. With unions Roblox registers it as 70 parts still. Also, there are reports of CSG issues (invisible blocks) that come with unions.
For some things I think using unions are fine. For example, unioning grass blocks to stop z-fighting. For others, like making a lantern, definitely use blender. It’s more reliable, it makes less lag and you’ll get a better product.
If it isnt backed up though, a union is permanently gone/corrupted, plus, to back it up, you’d probs have to upload it as a model or save as a place file which sounds not so good.
Meshes are already created from you meaning you probably already have a save file of it, plus, putting it on automatically keeps it saved and you can adjust it in another program easily with textures and more.
Meshes in my opinion are better in terms of reliability but if you want something quick and fast, unions are you go to thing for speed.
Ah Unions, Definitely a very interesting topics. Unions can be reliable In cases small but big cases like making a building a union is a lot of stress. Most of the time you make the union but then the union could ruin the whole building. Which took most of the work and it is a terrible feeling. So in some cases unions are reliable yes.
Unions are completely reliable and trustworthy.
They can bug out on you sometimes, but that’s the craft of working with them. You figure out what works and what doesn’t. Though that works contrary to what some people may want in terms of freedom, it gives you an excellent look of what you can easily do with unions and what you should probably do with Blender and stuff like that.
