I finally managed to make a super accurate outer cage for an oversized sweater with no errors! Here are some tips that I wish I knew sooner.
If you ever find yourself trying to research how to make layered clothing, more so the outer cage, you probably tried to look up one of these errors:
cage vertices intersect clothing
unnecessary cage edits
not water tight
outer cage extends too far
modified uv map
non manifold geometry
the number of cage vertices between the outer and inner cage dont match
âSceneâ object has no attribute âcheckResult_IntersectionInnerâ
I encountered all of these errors many times until I learned a few specific tricks. It still takes me a long time to make an outercage⌠several hours. There just has to be more efficient techniques and if you know any please reply below.
Firstly check out this video. Its very simple but shows the entire process of making layered clothing. I didnât make this video but I reference it all the time. The part about outer cage sculpting is a little too simple if youâre trying to make a more complex item but its a good start. https://www.youtube.com/watch?v=vxKg1btrRIQ
The easiest change I personally have made to how I make outer-cages is enabling the âMagic UVâ addon.
With this addon you can use a lot more transformation tools and avoid the âmodified UV mapâ error. For example you can now use Scale and Vertex Slide! After youâre ready to export your accessory, click the inner cage. Press copy and select âmap1â.
Then select your outercage. Press paste âmap1â
Then you can export with no modified uv map error!
Initially when I was making outercages, I thought the entire cage had to cover 100% of the clothes. This isnât necessarily required.
My example is a screenshot taken from blenderâs viewport. You can still see a lot of the sweater.
Looking a little closer, even though the sweater is clipping through the outer cage, all of the outer cageâs vertices are outside of the sweater. You can ignore this clipping without worrying about the âcage vertices intersect clothingâ error, as long as every outer cage vert is visible.
As I was first learning to outer cage I also found myself wanting to reference other itemâs cages. I couldnât find out how to download cages from studio. However I did find this chrome extension: BTRoblox - Making Roblox Better (google.com)
There have been past instances of chrome extensions hacking accounts so I make sure to only install the extension in a separate browser with an alt account. This one does have 4,000,000 downloads but itâs best to practice good account security anyway!
After you install the extension, go to an accessories page. Click the menu by shopping cart. Follow my screenshot for the right menu and click the little chain link button to open the cage mesh page.
Itâs a little hard to see in my screenshot but there is a download button. Click download as .obj and you can now import this cage right into blender.
A few more small things to keep in mind. The errors ânot water tightâ, ânon manifold geometryâ, and âthe number of cage vertices between the outer and inner cage donât matchâ can ALL be caused when vertices intersect each other. Make sure no outer cage vertices intersect any faces they shouldnât, including the inner cage.
To avoid âunnecessary cage editsâ try not to edit ANY vertices you donât need to. Try to not use Proportional Editing on large areas. When sculpting make sure your brush has âfront faces onlyâ checked. Any unnecessary edits can be fixed by enabling snapping to vertex and then snapping to the inner cage.
Thatâs it! At least what I know. Please share any knowledge you have on editing outer cages efficiently. My technique still requires hours of patience depending on the complexity of the clothes. Either way it definitely takes some practice.
