Mesh or Parts more resource hungry?

[DrBenRot]

I need several iterations of a chair model in my experience. I want to do vintage chairs with lathed legs. I could build up every leg with Roblox standard parts as a union (cylinders and cones, around 7 parts) or do a mesh in 3Dmax and import it (around 50 vertices). Which solution would be more performance friendly?

As far as I know, Roblox unions create extra triangles and have many other performance-related issues, so importing everything from other software is the best solution.

However, unless this chair will be around your scene hundreds of times, 50 vertices or some unions are mostly the same and won’t affect performance as much.

Honestly odds are you’ll never need to use UnionOperations. I’ve never needed them nor have I ever met someone who genuinely needed to use UnionOperations. (besides for CSG editing, but that’s not what you’re using them for) When creating a UnionOperation, or a Union, Roblox will generate its triangles/topology so you will be able to visualize what the object looks like. However, Roblox isn’t perfect and it ends up creating unnecessary triangles, causing them to be rendered, and overtime these …

I’ve been summoned here. [stop using unions] [unions are bad 2] Unions are by all means, really bad.

What’s your use case? Are you making something like, for example, multiple objects floating up and down all in sync? In this case, you should group the multiple objects, set a primary part, and apply a script to the model to control the primary part of the model, which will move the whole model with it as long as it is anchored. That’s the right way to do it and you should do it like that for ease of modifying/moving these objects in the future You shouldn’t union them for this use case, but…

Anyways I recommend you read the entire thread, there’s a lot of valuable posts there.

Thanks a lot, this pretty much answers it.
There won’t be hundreds of the chairs, but still around 50.
But the chairs were just an example, because I was working on them when I wrote the question. There will be much more models in the experience where this information will be relevant.
So thanks again.
