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?

also: monster's solution to the FBX scale import problem:

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?

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.
