Hi

I have two waird errors in my model

1'st

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

* Cannot generate ST coordinates

2'nd

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE">

* Non-linear mapping

Any body know how to fix this errors, please help

First error I guess means thatno tangent can be calculted for the vertex but I dont know how this can be fixed. Second one, dunno.

ST coordinates means the UV mapping is fooked up or parts have been mirrored.

Non-linear can be fixed by triangling the face/faces.

I'am making new face and UV but it doesn't help

Hi,

Hope you don't mind me using your thread as well Martin_BM but I am having afew problems also  

See I'm trying to import an .obj file exported from blender. Everything goes fine, but once in O2 my normals are acting very strange. When i'm on the far side I can see the faces fine, but when I look at it from close up , they just all go invisible. The faces are all still there, just not showing when I move the camera near them, if you get what I mean...really confusing me.

I have tried recalculating the normals in both programs (both inside and out), and tried all the different export options from (blend>.obj).. but am still left wondering what I am doing wrong.

From what little I understand, i'm thinking it has something to do with the blender export .obj script, as I had afew problems with normals on other meshes which I exported to .obj and then onto XNormal. Sadly the .3ds export  script from blender does not export kfdata so I am unable to use another export option besides .obj.

Is this just my model that has something wrong with it?

I ran alot of checks to make sure their were no gaps between any of the verticles and it is 6k polys but I am running out of ideas on what to do next

Here is an image of what is happening if it helps.

If anyone has encountered this problem before or knows what I am doing wrong, I would really appreciate if you could offer any advice which might help out.

No textures are being stretched at all?

@Bracken,

Use anim8or, it will export Kdata. just import the .3ds from blender and export a working .3ds from anim8or (making sure you check Dummy 3dsKdata in Options > Debug before exporting)

I got the same error with my structure in O2 and tried to find out wy. Something is weird here.

Do like this:

* start a new session in O2

* Hit F8 - create cylinder

* Put in some values and hit Enter

* Go to "Structure" - "Check faces"

* You will find that the cylinder is marked as " "Cannot generate ST coordinates"

Edit: Think it has to do with textures. The faces are all whithout textures at the moment so maybe no worries.

This is only warrning, if everything in game works fine don't bother

These are Warnings not Errors.

Warning means something is possibly not looking allright.

If everything is looking allright - ignore them.
