Importing FBX ?

Unity Engine
1

In the shot you can see an imported airplane in fbx file format from Blender 2.49b. And you can see an imported airplane in fbx file format from Ultimate Unwrap 3D Pro, newest version, newest FBX plugin.

Oh, you cannot see anyting? So do i :smile:

Could somebody please enlighten me what`s going on here? I thougt FBX is the supported format for Unity. :slight_smile:

Attached the two fbx files, plus the original obj file.

weā€™ve encountered a similar problem, where parts of the mesh didnā€™t show. What happened was that unity flipped the normals of some groups in the mesh, we have no idea why. Any other supported format did well, only fbx gave us troubleā€¦

Thanks for your answer. So it`s not just me :slight_smile:

Hmm, your aswer is not very encouraging though. I may need to import some animations at one point. And then OBJ is no alternative. Any recommendations?

we did the easy thing: go into max and flip the normals of the group thatā€™s flipped. :wink:

Iā€™ve tried working with 3 formats: OBJ, FBX and DAE. Allthough OBJ is very solid, you canā€™t indeed use animations on it, so thatā€™s out of the question. FBX works perfect 9 out of 10 times, but that 1 time itā€™ll give you hell while you try to fix it. DAE I gave up on, because the mesh as well as the animation completely got fucked up.

As weā€™re just working with Unity for 3 weeks, we didnā€™t found any solutions to this problem yet, but Iā€™ll try to keep you posted

Can you see the model in the preview window on the right bottom?

I donā€™t know about unwrap3D it worked for me the other day when I tested it for a friend. One thing to watch out for is the scale the model was originally created at.

Unity imports .FBX with a default scale of 0.01. If you model at a real scale like 1 unit = 1 meter then when imported into unity the model will be so tiny as to be invisible.

WHen I import my models at the correct scale, I set the import scale within unity to 1. That makes everything load 1:1 between my 3d app and Unity. So a 1,1,1 box snaps to a 1,1,1 grid perfectly in the engine.

So I recommend checking the fbx import component of the UI and seeing what happens when you raise the scale to 1.

Thanks Tysoe, that was it. My mesh is there. But it is so tiny that i needed to zoom in by a big amount until they became visible :slight_smile:

Counts for both meshes, the one from Ultimate Unwrap 3D, and the one from Blender.

Odd enough, when i import the blend file the scaling is okay :slight_smile:

Thanks for help everybody :slight_smile:

A little tip: if you have your object selected, press ā€œFā€, and it will zoom automatically to the object

Thanks for this tip. I already know about F key. I just didnt hit it because there was nothing visible where i couldve zoomed to. Whish i had. Zooms indeed in ā€¦ :slight_smile:

:wink: yeah, I must say Iā€™ve experienced the same problem a lot as well. Problem is that this is such a simple problem that it doesnā€™t come to mind :smile:

Yes, those are the meanest :lol:
