3DS Max Target weld issue

HAHAYOUDEAD

Hi everyone!

I'm new in 3D modelling, so forgive me if this is a stupid question.

I need to connect walls with ground for a platformer game. I decided to use target weld for this, because it seems like an easiest way. But there is an issue:



When I'm welding two vertices like this, I expect selected polygon to be deleted, but instead it collapses to zero-width one, so vertices don't really welds, they just both moved to one place.

The question is: is there a modifier or tool to remove all these thin polygons, or I should stop using target weld?


Sorry for any language mistakes.

I can't reproduce your problem. Target weld works for me when I do what your are doing above. I do however have a script that delete zero area faces. Just select the objects you want to run it on, and drag the script from Windows Explorer into the viewport.

BTW, save your scene before you use it, and there may be some verts you need to weld after.

Thanks a lot for the script!

Apparently, I don't understand how the target weld works. I just applied the Reset XForm modifier to object from the first screenshot, and now target weld just won't connect vertices at all. Is it somehow depends on coordinates?

Make sure there aren't any other vertices anywhere on the polygon (more than 8 on the whole mesh) and remove them if they are. It could be a topology problem, you could also select all vertices and weld with a low threshold to see if the polygon dissappears. In general, you can't weld two vertices in max that don't have an edge connecting them, that could happen, it might be a topology issue like so (exaggerated):

Thanks for response, huffer.

There is no topology issues as far as I can tell, it's exactly 8 vertices in my model, and faces are not flipped. Although, I've tried to exported my thing as FBX, and imported in new scene, target weld works as expected. I assume, there is some other kind of trouble in my original scene.

You could have a face with flipped normals, or a polygon overlapped behind the ones you see, but if there are no issues and it doesn't work I usually convert to editable mesh then back to poly and it kinda resets some issues.

HAHAYOUDEAD

Yes, when I exported it as FBX, it was editable mesh, so I converted it to editable poly and it fixed the model. Thanks for help!

This is some strange trouble with welding though
