Errors with Bew Model When Changing Weight Slider

[commieanarko1986]

I've been working on creating the weight slider variants for my Nordic Trollbone Armor, and I've found a weird glitch. If the weight slider is completely to one side or the other, the model shows up fine, and uses the correct model version. If the weight slider is in the middle anywhere, I get a bizarre effect. I've attached a picture to show what it looks like.

 

I would appreciate it if anyone could point me in the right direction to fix this.

Well, that blew up nicely now, didn't it? http://forums.nexusmods.com/public/style_emoticons/dark/laugh.gif

 

Looks to me like a skinning problem, import into Blender (or whatever you use) and check vertex weights, might be that they went to hell on export.

 

Tends to happen to me sometimes that the mesh just explodes, it's almost always vertex weights screwed up on export and once a missing bone (yes, yes, I'm stupid and I accidentally deleted a bone http://forums.nexusmods.com/public/style_emoticons/dark/facepalm.gif).

Here's an update with a better picture to understand what's going on:

 

If the character has a weight of 0 or 1 the model is completely fine. If it's any weight in between, then part of the new part of the model flips out. Is there something in Nifskope that connects models?

I would say you did some operation that changed the vertex order in one of the files (_0 and _1). Both need to have the same vertex order, and no, there isnt anyway to correct the vertex order, you must start from scratch the skeleton bone thingy in either _0 or _1.

Fixing your armor for weight sliders has always been a tricky business. The thing to remember is that everything between the _0 and _1 versions has to be the same. Vertices count and skinning has to be the same. Even the file size has to be the same. If you edit one to fix the textures in nifskope, you have to do the same to the other. When scaling up (or down), the only thing you can do is move vertices.

 

I had a quick look at your mod. Right off the bat I can see the file size difference between the _0 and _1. So it's no surprise that it's blowing up. The date stamps are also different, I just find better success when I do it all in one sitting. Do you use Blender or 3DS max?

[commieanarko1986]

I use max.

[Ragicka]

I use max too and the reason I ask is that there are a couple videos (

and

) that really helped me with weight sliders. In fact, the whole series has a lot of great information.

 

I'm not getting the exploding mesh with the weight slider. There's some movement around the neck and a gap develops between the arms and hands midway. The armor stays the same size at 100 weight but looks ok. I went ahead and had a quick look in nifskope to compare the _0 and _1 files. Without getting into gritty details, there are mismatches in vertices count, NitrishapeData and BSLightingShaderProperty settings. Most of those mismatches are in the banditarmor and banditbody nitrishapes.

 

I think you should concentrate on the ribcage mesh. Start with the _1, export the ribcage by itself as ribcage_1.nif (you'll need to redo the bsdismember). Scale the the ribcage_1.nif to fit the bodym_0.nif bandit armor, (do not touch the skin data or bsdismember) and export only the ribcage as ribcage_0.nif.

 

Use nifskope to transfer the _1 ribcage nitrishape to the vanilla bodym_1.nif and the _0 ribcage to the vanilla bodym_0.nif. You'll need to redo your esp file as well, I think. When I replaced your files, there was no change. But replacing the vanilla bandit armor with my edits worked like a charm.

I've had a similar issue with vertices exploding all over the place, when the weight slider is in between.

 

If your a Max user, check my post on how I got it to work:

Big thanks to VectorPlexus and Ragicka for providing helpful information and input. :B
