import the image ref and start with a plane
extrude the edges to stretch the shape of the plane
we can add loop cuts to add more geometries
we now want to create the raised area of the crust
we select the edges of the cross
extrude, then press ESC and then scale
edit the vertexes to shape the crust
now we create faces.
extrude the vertex in the image, select them and F to form a face
continue doing that for the rest of the shape
select the external edges
again E + esc + scale
repeat another one
go to the UV image editor and load the texture of the loaf
click U and then project from view
rescale the uv
edit the uv projection as needed
now we still have a flat plane
O to set proportional editing
set editing to sharp
G + Z
scale the bottom edge in
scale the other outer edge as well
add a surface mod
select the cross
drag it down
the shape is still too squared so let’s select the 4 outer vertexes
O + S
select the base
S + Z + 0
Add a material and image texture and we should already be able to see the texture
We can now improve the crease of the internal cross with shift + E
smooth shading
Now add displacement mod
click on New
we need to add the image texture to the displacement modifier
set the uv map in the displacement setup and then increase the sub surf amount
reduce the strength of the displacement
Note: the maps can be generated with Crazy bumps http://www.crazybump.com/
We now bring in the normal map
Now we need to make the materials organic. The light must be able to pass through the object. Sub surface scattering
We can now add a glossy shader
