How to fix this cube ?

Questions & Answers

I have imported cube with texture from Blender and it imports like that.

When I place it, it looks normal, but when I generate it through the code it appears like in the inspector.

You would need the following script. I dont remember where I got it from, but it makes the Blender models right side up for me. Just make sure to put it in the “Editor” folder and whatnot.

using UnityEngine;
using System.Collections;
using UnityEditor;
using System.IO;
using System.Linq;


public class BlenderAssetProcessor : AssetPostprocessor {
	public void OnPostprocessModel(GameObject obj  )
	{

		//only perform corrections with blender files

		ModelImporter importer = assetImporter as ModelImporter;
		if (Path.GetExtension(importer.assetPath) == ".blend")
		{
			RotateObject(obj.transform);
		}

		//Don't know why we need this...
		//Fixes wrong parent rotation
		obj.transform.rotation = Quaternion.identity;
	}

	//recursively rotate a object tree individualy
	private void RotateObject(Transform obj  )
	{
		Vector3 objRotation = obj.eulerAngles;
		objRotation.x += 90f;
		obj.eulerAngles = objRotation;

		//if a meshFilter is attached, we rotate the vertex mesh data
		MeshFilter meshFilter = obj.GetComponent(typeof(MeshFilter)) as MeshFilter;
		if (meshFilter)
		{
			RotateMesh(meshFilter.sharedMesh);
		}

		//do this too for all our children
		//Casting is done to get rid of implicit downcast errors
		foreach (Transform child in obj)
		{
			RotateObject(child);
		}
	}

	//"rotate" the mesh data
	private void RotateMesh(Mesh mesh)
	{
		int index = 0;

		//switch all vertex z values with y values
		Vector3[] vertices = mesh.vertices;
		for (index = 0; index < vertices.Length; index++)
		{
			vertices[index] = new Vector3(vertices[index].x, vertices[index].z, vertices[index].y);
		}
		mesh.vertices = vertices;

		//for each submesh, we invert the order of vertices for all triangles
		//for some reason changing the vertex positions flips all the normals???
		for (int submesh = 0; submesh < mesh.subMeshCount; submesh++)
		{
			int[] triangles = mesh.GetTriangles(submesh);
			for (index = 0; index < triangles.Length; index += 3)
			{
				int intermediate = triangles[index];
				triangles[index] = triangles[index + 2];
				triangles[index + 2] = intermediate;
			}
			mesh.SetTriangles(triangles, submesh);
		}

		//recalculate other relevant mesh data
		mesh.RecalculateNormals();
		mesh.RecalculateBounds();
	}
}
