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?

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:
[COLOR=SeaGreen]// This function will over write the default Unity import scale of 0.01.[/COLOR]
[COLOR=DarkOrange]class [/COLOR]DefaultMaxSceneScale [COLOR=DarkOrange]extends [/COLOR]AssetPostprocessor [COLOR=DarkOrange]{[/COLOR]
    [COLOR=DarkOrange]function [/COLOR]OnPreprocessModel [COLOR=DarkOrange]() {
        if ([/COLOR]assetPath.Contains[COLOR=DarkOrange]([/COLOR][COLOR=Yellow]".max"[/COLOR][COLOR=DarkOrange])) {
            var[/COLOR] modelImporter [COLOR=Red]:[/COLOR] ModelImporter [COLOR=Red]=[/COLOR] assetImporter[COLOR=DarkOrange];[/COLOR]
            modelImporter.globalScale [COLOR=Red]= 1.0[/COLOR][COLOR=DarkOrange];[/COLOR]
        [COLOR=DarkOrange]}
    }
}[/COLOR]
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.

AmplifyCreations · Nov 2018

Greetings fellow Unity developers,

Hope we don't get in trouble for posting this here as well but we're very happy to announce that Amplify Shader Editor now supports the new Unity 2018 Substance Plugin. Manipulating Substances via shader is a great way to tweak your assets without needing to recalculate them.
