FUCK UNITY.

nah, jus kiddin'

Woohoo! Finally, Unity gets Polycount's love.

Crossposting from the Unity Sutup Thread, maybe we can add this to the original post once solved?
[...]http://i.imgur.com/ha8j5.jpg

is this the correct unit setup or would i set the system unit scale to centimeters as well?

also: monster's solution to the FBX scale import problem:
[...]Put a text file (javascript) in ...\Assets\Editor\ImportSettings.js (make the folder if needed.)

Paste this code into it and save it:


// This function will over write the default Unity import scale of 0.01.
class DefaultMaxSceneScale extends AssetPostprocessor {
function OnPreprocessModel () {
if (assetPath.Contains(".max")) {
var modelImporter : ModelImporter = assetImporter;
modelImporter.globalScale = 1.0;
}
}
}
I haven't tested this, but I think it will work. You can remove the .max check if you want it to scale all models on import.

As for me, my unit setup in Max is 1 unit = 1 centimeter, and display is set to generic units. I've never had a scale problem. [...]

and the last thing: the axis problem: did anyone ever get rid of it?
just found this, which seems to describe the problem (http://forum.unity3d.com/threads/10343-How-to-get-the-XYZ-axis-right-%283DS-MAX-Unity%29/page3) pretty spot on. [...]

The coordinate system conversion is still unsolved and I doubt you'll be able to fix it yourself without writing a custom FBX importer, but you can help UT notice this by voting this up

class MyFilePostprocessor extends AssetPostprocessor {

function OnPreprocessModel () {
// Set imported models to scale 1.
// Disable swap UV channels.
var modelImporter : ModelImporter = (assetImporter as ModelImporter);
modelImporter.globalScale = 1.0;
modelImporter.swapUVChannels = false;
}

function OnPostprocessModel ( object : GameObject ) {
FixMaxImport ( object );
}

function FixMaxImport ( object : GameObject ) {
// Unrotate root transform.
object.transform.rotation = Quaternion.identity;

// Get all meshes and unrotate them.
var meshFilters : MeshFilter[] = object.GetComponentsInChildren.< MeshFilter > ();
for ( var j : int = 0; j < meshFilters.length; j++ ) {
FixMesh ( meshFilters[j].sharedMesh );
}
}

function FixMesh ( mesh : Mesh ) {
var resetTransform : Quaternion = Quaternion.Euler ( -90.0, 0.0, 0.0 );


var newMeshVertices : Vector3[] = new Vector3[mesh.vertexCount];
var newMeshNormals : Vector3[] = new Vector3[mesh.vertexCount];
for ( var i : int = 0; i < mesh.vertexCount; i++ ) {
newMeshVertices[i] = resetTransform * mesh.vertices[i];
newMeshNormals[i] = resetTransform * mesh.normals[i];
}

mesh.vertices = newMeshVertices;
mesh.normals = newMeshNormals;
mesh.RecalculateBounds ();
}
}

This should unrotate all models that don't have animation on import.

I've tried fixing skeletal animation - got somewhere close on very simple rigs - but it's far harder to fix... the maths and internal workings is a little beyond me.


Also, I have some Unity related tutorials (mostly shader stuff) up on my blog; http://www.farfarer.com/blog/ - might come in handy for some.
