Blender to Unity problems

I’m just getting into the whole Blender/Unity thing and eventually want to try to make a game after I get significantly better.

Anyways, I’ve been having trouble with every model I’ve made in Blender and tried to import to Unity. Mainly, the colors imported are wrong and there are always pieces you can’t see at a certain angle.

The engines on the left aircraft can always be seen through from the sides or the front. How would I fix this?

One of my other problems is that the mesh collider is always facing different ways than the model.

What’s the problem there? Thanks in advance!

Your normals pointing in the wrong direction. Go into edit mode and press ctlr+N to recalculate the normals. Typical beginner mistake which pops up every week here :wink:

Not sure about the mesh collider though. Never saw such problem.

The recalculate normals command worked on the first one as far as I can tell, but it only changed which pieces you can see through on the second:

Could something just be wrong with the model? I tried both inside and outside normals.

Do it manually in blender, check every face.

Ah, alright. I did each face individually instead of the entire selection and it worked. Thanks!

Any ideas on the mesh collider?

As Fishman said, in this case you have to select the polygons with the wrong normal direction and flip the direction manually (look for the flip direction command in the tool shelf on the left side).

I would also suggest to use a edge split modifier for the spaceships. Otherwise you get some ugly smoothing artifacts like on the wings of the second vessel in picture one.

I’m not sure what you’re referring to; do you mean the jagged edges?

interesting interesting project there

Think so? Hah

ye… can i know more?

Well, what I’m aiming to do eventually is way, WAY out of my current skill level, but I’m beginning to make the models for a vehicle focused combat game. It’ll be heavily inspired by Planetside, since the sequel was a major letdown. I have very minimal experience in scripting, next to none in animation, but since I’m DECENT at modeling I’m trying to do that first… but trying to do this recalculating normals thing is annoying. Can’t move on until the first ship is fixed. It seems like when I close off the wings, you can then see through the tail… argh…

customizable craft involved?

Very. Was thinking that it isn’t going to be all the same weapon models and tracers but with different stats, instead each weapon will be unique. (If I ever figure out how to do it)

I just wish Unity would import models exactly how they appear in Blender, and I wouldn’t have any problems with that.

No.
I mean the black shadings on the wing. You should split the edges. Otherwise you will get shading artifacts because Unity (as well as any other 3d software) tries to smooth these polygons at such sharp angles, which results in such black shades on even surfaces.

Not sue about your collision mesh problem. Did you rotate the axis in the local space, or something?
