Blender 2.49a: help with normals

[QuiteTheTail]

Surely someone has encountered this problem before, can you please assist me?

I'm talking about editing a pre-existing mesh in blender, in the attempt to reconstruct parts of it to eliminate small defects or to fill gaps. What I do is simply deleting some faces, and using the F key to fill the gaps creating new triangles. Bear in mind that I do not create extra vertices, I just recreate those that had been deleted.

Fixing the normals is a hellish work, and once exported the nif, there are notable gradients in the texture, both in Nifskope and in game. In rare cases the relevant parts of the mesh become invisible (loss of weight painting, I presume). When selecting the vertices to rebuild the faces, I'm using the right-hand rule, but it makes little or no difference.

Example:

 

 

Until now, I thought that rebuilding the UV map was unnecessary, but I started having my doubts.

I am aware there is a normal patch for Blender. Maybe it could fix this kind of problem?

If it's so, where can I find it?

[Suludi]

If turning normals outside doesn't help, try eliminating double vertices.

[QuiteTheTail]

Yes Suludi, I've already tried that. Some vertices were removed, but the problem remains. Perhaps newer versions of Blender are not affected by this problem (unfortunately, 2.49a is the last Blender version supported by niftools, at least for now).

Recalculate normals, if necessary make the mesh double-sided or separate the problematic part and flip it.

 

And if all else fails, try redoing the UV map.

It will be done! Thanks for the tips.

 

The detail in the image is from a leather strap. In the original mesh there was a certain asimmetry in the model, so I duplicated (Shift-D) a particular selection, flipped/translated it, and used it to replace the defective part. The merging looked perfect in Blender, but once in game I got a bitter surprise (invisible triangles). Now I was busy trying to fix the problem, when the normal nightmare started.

You're right, it's version 2.49b we're talking. The thread title and my previous comments report 2.49a by mistake.

Do you know that NifTools acts in latest blender?
Of course it is different from NifTools which acted in 2.49b.
Look at here if you are interested in it.

Because I do not produce mod anymore, I try it only once.
I tried it in Blender2.75.
If you do not get a wrong parameter, it acts.

 

If you want to improve a problem of the object, I think that it is the best to show the .blend file which pulled out only the object.

This is great news. Thanks!

Oh, I wasn't correcting you. I didn't even notice it said 2.49a

 

I'm just not fond of the old version. I removed my comment so I wouldn't derail your topic, and I just realized that you commented.

Looks like Vaelorian's advice was good. I only had to select all faces and use Mesh>Normals>Recalculate Outside.
