So, i've selected the lower body part and hit that '-1". It make it better, but still not perfect, because while rotating model, the seam between lower body part and upper body part still can be seen.
Hmm, yes, you was right, there was a few vertexes that was pointless on the lower part of body, however, it did not made a much difference after i removed them, the normals still not ideal, i believe there might be a way to calculate them, because fixing it by hand is an option, but this is a much time cost and not very accurate way to fix this.
You can fix this by selecting the vertices of the seam (overlapping vertices of two different geosets) and then clicking the "Average normals of selected vertices" button.
Sure, i did that, model looks way better now, but still not the best as this is manual way to fix. Anyways that a way. So thanks everyone, however, i still believe that there is more faster and right way to fix that. Also, when i did such operation with normals in MDLvis, i've got an error in War3ModelEdidor saying something about "MDVI Group" or like that. So this a working way, but in the same time can broke model. But it works in game well. In all being said, this is a way, but not a perfect or a good way, but working way.
Does it actually work for you? I tried it on a few different models and it doesn't seem to do anything.
It generally works for me (although you need to use the more later builds; the earlier builds it doesn't work). One thing for sure, though, is Mdlvis can't fix anything about Normals and it'll only make things worse.
