All of the parts were exported as FBX in to unity and the mosque was build in there. The final project

Interior

For the interior dome first created the top part of the dome. By using a sphere deleted the bottom half of the faces and after that extruded the bottom edge

Next created one of the triangle polygons. Used a cube fist added as many division as needed to create the form then extruded the inside faces. Then by using the Duplicate spatial tool duplicated the  mess in 360.

The next part is created by using the form of the walkway and again duplicated in 360.

 The next step was to create the candler I created the top part of it with a cube and the Duplicate spatial with making sure that they are going to move on the x and y axes so I can get the effect of steps. The leaves were created from a sphere. Created one leaf in the needed form by deleting all of the unneeded faces. Then duplicated it in 360.

Interior

For the interior walls used the same walls from the walk way and reorganized them.

The shape in the middle was create from a cylinder the same way as the windows. After the need form was created by using revolve tool the I was able to create the shape.

Then every other face horizontal face was selected and extruded and then beveled.

Mosque Front

The front of the mosque was created from cubes. I extruded the edges to create the basic for of it added the window the same way as on the Domes by making the main mesh live.

Then from a cylinder created the star shape added a few decisions and extruded the top part. Then deleted all of the sides of the star and left only one and added windows to it. Then by using the duplicate specials created the star.

Minaret

Next step was to create the minaret.

I used Cube to create the base. For the second part I used a cube again. Added as many division as I needed. For the windows used the same shape from the dome windows and the same technique (Making the main object live). For the lattice I used cylinder and twisted it, then beveled all of the edges and extruded the faces between the bevels and the deleted the faces in between.

For the top part used the same top from the dome.

Sheikh Zayed Grand Mosque 3D Model

Next step was to create the entrance from the from of the Mosque.

I used the form I created for the entrance and reshaped it a little bit to get the new shape.

Sheikh Zayed Grand Mosque 3D Model

The next step is to create the form on the top of the column.

First I created a high poly of one of the leaf on from the firs lair.

I created it by using a plane and added some divisions on it. Then reorganized the vertices to create the form I needed. After creating the form the next step is to create s low poly from it. First I made the object live and by using the Quad Draw tool I created a shape that was close to the one I have. Then I baked it. The next was to create high poly of the form underneath the leaves. And baked it as well.
