Problem with shadows in Unity

[requimrar]

Help. (Again, I\'m sorry). Finally, I\'ve gotten the hang of texturing (albeit cumbersome, because blender insists on having retarded gradients on the UV map outlines). Now I\'ve finalised the model of my 1m tank and I\'m mostly fine with the texture. However...

I\'m using Unity now, simply because I don\'t have to combine all the objects\' UV maps into one texture file; it makes my life easier. But back on topic: My shadows are slanted, instead of being parallel to the ground (in reference to the SH; in the VAB it is also slanted).

Pictures:

This is in Unity; I had to shift my view around because it appears that when looking head-on, I cannot see the shadow. But you can see that the problem lies with Unity.

This is in the Spaceplane Hanger; Clearly the shadow is not in line with the stock tank.

This is in the VAB. The same effect as above is also observed.

It doesn\'t happen when I use the old DAE importer method.

I can\'t trace the problem; I\'ve removed all the unnecessary objects from my scene. The Blender camera and lamp, and the Unity Main Camera and Light.

What?

Erm. The pictures aren\'t showing.

Whoops. Sorry, rightclick -> new tab. Flickr is like that.

Ok. Hmm. I\'m getting similar shading bugs like this as well. My parts usually end up way too shiny in the editor preview. Fine everywhere else though.

[requimrar]

Nobody? Really need help here.

[requimrar]

Bump.

Here\'s a more detailed explanation of the problem:

With the stock tank, when I stack 2 of them, the shadow is always parallel to the tank; not the ground. When it\'s not lit, the light simply fades away.

However, with my tanks, the shadow is drawn at an angle; the light side is facing the sun, however it is offset by about 20 degrees. The biggest problem is that the shadows are drawn separately on 2 tanks; meaning the shadows don\'t form a line, which look really bad.

Now for the second, and worst problem by far:

MY PARTS EXPLODE ON THE LAUNCHPAD!!!11!!!!!!!111!!!1!11

Yea. All the parts, both tanks and my engine. I don\'t see why; I\'ve tried setting the crash resistance to 100000. I\'ve tried putting just a command pod above my parts. Nothing. They. Always. Explode.

All my parts have a node_collider; all those node_colliders have a Mesh Collider component assigned to them inside Unity. I\'ve even tried assigned individual objects their own colliders. (I don\'t join them)

Someone doesn\'t want me making parts for KSP.

Also the inside of my engine nozzle is transparent; I think a recalculate normals will fix it.

But the explosions. I have all 3 .blend files attached, as well as the unity scene.

This is either a problem with your model, or the fact you have two node colliders. Make sure your engines and fuel tanks are centered. You don\'t want them below or above the grid. Also, with the new mesh colliders in unity, you don\'t need a node collider, so remove that and make a collider directly from the mesh. Hope I helped. I love your parts btw.

[requimrar]

Well I pretty much solved the exploding parts problem; check 'convex' for the Mesh Collider.

Now those annoying shadows however... I can find no cause nor solution.

Do you mean the shadow of the tanks projected to the ground ? Could you post a picture? Your 'shadow problem' might simply be bad smoothing...

[requimrar]

Alright, here\'s a pic. Pretty self-explanatory; the 2 tanks\' shadows are completely screwed up. Simple as that.

[Maraz]

Yes, it is bad smoothing.

I don\'t know Blender, but there should be a split edge modifier somewhere.

Damn it sure fixed the problem. Thanks so much. For some reason when Nut007 asked me to do that same thing, it didn\'t seem to have any effect. Maybe I did it wrong, but I dunno. Either way, thanks so much for your help, now to RULE THE WORLD!

[requimrar]

Dammit, I forgot what options I used. What are the options needed to get that model working properly?

I just select all, Modifiers > Edge Split > Apply.

I don\'t know which boxes to check; it worked for one of them but not for this one. I don\'t know what I did exactly...

Also those stupid UV maps. Why can\'t blender just export a damned SOLID LINE??? Cheetah3D can do it, just that it sucks. I don\'t understand the design decision to make the lines have retarded gradients.

Fixed OP\'s images. Reposting.

[requimrar]

Thanks semininja, but that is no longer my concern. Any Edge Split modifier setting should do honestly. The problem is those stupid UV maps.

[carmics]

I was able to fix the problem

The solution is in the right menu

(object modifiers/add modifier/edge split, then apply)

this solves the problem of the shadow
