FBX Accessory bounding box guide for 3D Modelers making Accessories

Here’s my FBX guide I made for people who might be running into issues with visualization of the bounding box while modeling


Full Bounding boxes visible


Hat bounding box and Front accessory bounding box visible with every other bounding box invisible

This is a model (With multiple objects) that helps Visualize the bounding boxes that multiple accessory slots use, I made this because I was really tired of having to go from studio to blender fine tuning things, It’s not 100% perfect but it is 98% perfect which is good enough for me and keeps you from being in the dark about if you accidentally made your accessory too big

Usage: Just import this into your third party 3D Modeling program like Blender or other programs that can import an FBX and line up the torso or head (With all bounding boxes selected) and match the correct scale if need be to your own template (Must be a blocky avatar) turn on the visibility of the bounding box objects depending on what you’re developing, Just be sure to delete the whole guide and everything when you’re exporting

The bounding boxes have a very tiny amount of play compared to the actual ones on Roblox so just be sure to add a small cushion of space when you’re developing geometry that’s getting near the bounding box limits visualized here; It should be negligible enough that you shouldn’t have to worry about it unless you’re trying to fill the entire space up (Please don’t make a huge brick!)

The “Grip” and “foot” bounding boxes aren’t used in any actual accessories I’ve seen so far?? There’s probably like one or two accessories made by Roblox that use them; I included their bounding boxes anyways but since they’re both so large I have a feeling that they’ll probably get updated if they ever allow us to make those accessories so watch out for that.

Hope this helps any modelers making stuff! I’ll try to update this occasionally when roblox changes a standard and if I’m made aware of it; I also might release other guides if this one’s popular (Layered clothing, Avatar / character Creation (This one might be hard to do) )
