I made a store for Cyrodiil and Im having a couple issues with the mesh that I can't figure out. It loads into the game just fine but there are certain times where the mesh will just completely disappear. This happens whenever I look directly above, below, or to the sides of the store. It also happens when I try to enter under the overhang that is built into the mesh. If I upload it somewhere is there anybody who can take a look for me and see whats wrong with it?

Check your bounding boxes and surface normals, among other things. Are you using the original exporter? Max or Blender?

Bumping this to make sure zackg sees it

Maybe it's not related to exporter. I also have the same effect when I edit the mesh in nifscope, that is when I scale up or down, or when I invert the faces.

Crap. I do that all the time to meshes. :worried:

Scaling the mesh a little won't do it wrong, no worries Now if you scale it for like x3, then worry :laugh:

I remember once you mentioned you use blender...If you can't fix it on another way send me the mesh of the store and I'll import and re-export it in 3ds Max...I never noticed a similar problem on my architechture, so maybe it is the export

Can you send me the mesh plz, I will have a look at. Can't be it is the exporter. Using it every single day without any issues, so I don't think it's a bug and if it really should be one, it's in my interest to have it fixed. Will post on Niftools in that case.

Yup, I use blender. I normally never have issues with the exporter so Im unsure as to the cause.
Here is the link for the download. Go to the bottom right of the page where it says "save file to your PC click here" and click on click here.

As PK already suspected, it' seems to be a problem caused by a bunch of normals pointing into the wrong direction. Even if you recalculate the outside CTRL+N, still some are left. That's due to the mesh being such a puzzle of several single pieces. Blender cannot calculate that correctly anymore and MW's game engine may even have bigger problems with that, but mainly concerning collision. So you have to tweak it manually W-> flip normals. To visualize normals go to mesh tools more, like shown on the screen below, enable "draw normals" and size them up until you can see them properly. The lines coming out of the faces show in which direction normals are facing. In case it's an outside wall, they should point to the outside an vice versa if it's an interio wall. Even bothsided is possible.

When you turn on texture mode, you can see what happens ingame or in nifskope, faces or in your case whole roof is missing, cause texture is on the wrong side of the face.

Newest nifscripts export meshes textured bothsided by default. But you should change that in nifskpope, cause a textured inside of a model, which isn't even seen ingame, is a waste of fps. Each NiTriShape has a NiStencilProperty, which's value you can change in the block details. As I said by default it is set to "draw both". You should change it to "draw ccw" to only display the outside. Make sure normals are right first, else what you see on the next picture will happen.

Anythings else seemed to be alright. Couldn't reproduce any issue during scaling the model in nifskope.

Bump for zackg again.
