About the lightning, that's because the materials are set as unshaded, i edited a copy to undo that, but the result is awful, so i use that model as it is :c

I had the same problem with a few other models, and most of them are Grendel's models.
 
As for the lighting problem, that can be fixed but the editing the shading like @stein123 said.
It's the Normals. Material shading won't fix that, as stein tested.
If I recall correctly, -Grendel uses mdlvis to make stuff from scratch, and that's not efficient at Normal consistency.

Here you go.
I could have missed some inversed polys, since they were way too many, but even if I did, they will affect the model in a very tiny way that would hardly be noticed.
I also added a portrait camera.

EDIT: Fixed some other inversed polys that I missed

Sorry for the double post, I had to do it since an edit does not bring a notification

You are welcome.

To my knowledge, inverted polygons are, well let's say they are polygons that face the wrong way so lightning comes from the wrong direction
A polygon can only face one way, and it should face the way you would always see it from, else it would have a terribly odd shading.
More experienced modellers can say more on this than I could, I guess.

Since this model had way too many inverted polygons, that problem was hidden by making all materials non-shaded, that however is still a problem, because that is why the model had no shading at all.

What I did was, to make nearly all polygons face the right way (the way you would see them from) and uncheck the Non-shaded box on the materials.

I have to say thank you too! that's really useful, i myself wanted a fixed version of this model from a long time, i'll try this solution with other models to see how it works, one question, in wich program you fix the inverted polygons, on mdlvis?

Yep, I used mdlvis, but Magos is also a must since I use a trick with it to make finding inverted polygons much easier


The trick is, to make a TC layer for a material If there isn't, and then open the main layer and uncheck the two sided box, and make the filter blend.

This will make inverted polygons appear in a flat TC look, these are the inverted polygons, then open mdlvis, select each polygon with the flat TC, and click on Reverse normals.


After that, I revert materials to how it was before, (e.g a material had a transparent filter and then I set it to blend, after fixing the normals, I revert the filter to transparent again)
