I’m not sure if there’s any solution to this or how to go about solving this but this union I made is composed of a mere 32 parts. http://prntscr.com/joxvgf However when saved to file is a whopping 177KB.
A build that I made which used this union turned out to be much larger(space-wise; 50367KB or about 50MB) than anticipated which was cause for concern as I wasn’t able to upload it as a model. Is there some sort of trick I can use to achieve the same result look wise without using so much space?
It’s because of the inefficiently in CSG/Unions. Try remaking that part using blocks, cylinders, and spheres. You’ll likely save a lot of storage space.
You’re probably best off using a mesh - Unions each save their entire history of unions/negates (to allow you to un-union them) so it’s not surprising they rack up large file sizes
Unless I’m misunderstanding something, this still means that a union like the one in this post would have to store the info of 32 separate parts, rather than just geometry information. Otherwise you wouldn’t be able to completely separate a union back to the individual parts it’s comprised of
I highly recommend the use of Blender to achieve what you want, once you start to understand the hotkeys it’s a great experience for creating things like these, especially compared to the system for creating unions.
Here is how I'd achieve this in Blender without the use of hotkeys
I quickly recreated a rough version of your model for this example:
Change the amount of segments you want to bevel to whatever you’d like, I chose four for this example. I recommend messing around with this to get the result you want, but of course be aware that setting it too high will create a high polygon model which would use significant memory.
For the result you want, I recommend changing the shading to smooth. To do this, navigate to Mesh > Faces > and scroll down until you see “Shade Smooth” select this and it should produce the result you want.
The model you now have should be what you wanted, to export this into Roblox I use this process.
Once you click on the FBX option, it should prompt you to save the FBX to your computer. Before you do this I recommend changing the scale of the mesh to 0.01 so that the model is not massive once imported into Roblox.
If you have any questions regarding it or my tutorial let me know!
I tried to make it friendly for people who typically don’t go into that type of stuff because I understand how confusing it’s interface is
Also, if you want to mark the thread to have a solution so people can go into the thread expecting an answer, click the box with a check mark beside the “like” heart
If you could think of via Blender perspective, looking at something like that you could probably see there’s lots of vertices and faces which takes time to render, spheres are a lot of vertices being as smooth as possible.
You should get into Blender as meshes are much better if preloaded properly. Otherwise, they wouldn’t change that much as it would take as much time as it would for a regular union to load.
