Having an issue with my Mesh - Please help!

[crazyblocks234]

So, I am trying to learn how to 3D Model in Blender, I have made several things so far… However I am learning new stuff along the way. Today, I have made this Spiky Mesh.

It looks normal in Blender, It has all it’s Vertices, Edges, etc.

However, when I imported it into ROBLOX Studio, well…

It appears I am missing a Vertice. I don’t know why, It looks completely normal in Blender. (The mesh has 98 vertices, 96 faces.)

(I imported it as a .obj file at first, and it was missing several more vertices in Studio, but when I imported it as an .fbx, It seemed to fix some of the vertices.)

Please tell me why this is happening.

Thank you!

This may help.

@XAXA

If this was exported as an fbx, a quick way of getting rid of that is to export it as a obj instead. This works because the obj format doesn’t support vertex colors You can also reset the vertex colors yourself (if you’re using blender, then read this thread on blenderartists.org) and export it like you normally would.

I’m not experienced with this category, apologies.

Your mesh may also be triangulated incorrectly by Roblox. If recalculating/correcting the normals doesn’t fix your issues, then try triangulating your faces before exporting:

You should also turn this setting on. This setting “hides” a face when you’re looking behind it. This help a lot in debugging normals. This is in the display panel (the panel that you toggle when you press N), under Shading:

then try triangulating your faces before exporting:

How do I do that, exactly?

(Read the OP, you are indeed using blender)

Follow the screenshot in my previous reply. In edit mode, select all your mesh’s faces and then press CTRL+T.
