Magnitude of light falling on the mesh - problem

[ZuTheSkunk]

(Moved into separate topic as Grond asked.)

While creating the mesh for madness battle axe and warhammer - obviously by using the parts of other meshes - I've used the parts of armor; shield and boots in particular. Theoretically everything works fine, but in practice I see some strange issue with magnitude of light falling on those parts. They have identical settings in Material Property like the parts of original weapons, and still I see this:

I've encountered similar problem while trying to do something with statue from Kvatch - a bit charred one, according to the storyline. It's probably the same problem. How can I fix this?

My first guess is flipped normals. It's probably wrong though.

[ZuTheSkunk]

Normal maps of madness war axe and madness shield looks rather similar, so I don't think it's a problem of them. My guess is that there's some specific value in the mesh itself, that makes his base light magnitude higher or lower, unreachable from NifScope - or maybe reachable, but I don't know where it is? Changing values in Material Property doesn't help much here.

Grond means the normals in the mesh, there is a setting that allows you to flip the normals

[ZuTheSkunk]

Ah... excuse me, I haven't understood. Where's that setting then?

Well, there was no Flip Normals option, but was Face Normals instead. And this one has helped.

Thank you both, grond and IS.

O I am a Blenderhead - there's no Flip in Nifskope, only Face, eh?

I suspect that means to turn their 'faces' outward. It is almost the same.

I'm going to need a picture of the fixed weapon.

NOW PLEASE!

[InsanitySorrow]

There is a flip normals option, but I think it may depend on the mesh itself. I think that's why Zu only had Face Normals.

Not sure what your actual problem is, but by the way your pictures look,

1. Do you have multiple light sources at work?

2. Do you use a "drop light torches mod"?

3. How many meshes do you have loading? ;Check

4. If you have multiple meshes loading, the result is usually after more than one light source is lit(Ex. Torch)

The mesh will turn black(ish)

;5. What is your load order?...

To prove this: make a place where you will place the mesh. Next make another (duplicate same nif)mesh beside it:Label it so...(or just know) Then Place 4-100 extra meshes in the same pos on it. Start game, light torches,etc.

;If this doesn't work, then, I would guess it is problems with the mesh itself or normals. But multiple meshes will produce the same "Black results" This sometimes is the result of merging a mod(multiple? times) and not realizing you did so.(records that were missed)

;Open the mesh in blender...Open object(s)...Delete duplicate verticies on each object. Export. Don't Pyffi just yet. Test exported mesh in-game... Exitgame... Make a copy of the nif... PyFFI the nif... Replace and test again with the Pyffi'ed nif. If No Problems, Proceed as normal.

;Also while in blender check how many objects there are supposed to be...

That looks like a smoothing group problem, oblivion is famous for them when you look at them in a modeling program, the shading error near the blade is probably caused by a single smoothing group applied to polygons facing in opposing directions without supporting edges. The shading error near the middle of the head could be caused a cluster of long triangles welded into a single vertex.
