Hi Suzi,
nice that you take on the difficult task to create some tiles.
Actually, the
Rendering Setup in the
Tutorial has the camera setup at the right position and angle and there's already a 1x1 tile.
You can find it one Layer 3 in the blend file.
Just open up the file, select Layer3 (press
3). The camera should be centered at this tile.
If you want to make a 2x2 tile just select the tile in object mode, scale 2x (
s +
2).
Now select the camera and double the camera scale under
Editing(
F9)
Last step is to also double the output render size (
F10) (see
http://wiki.parpg.net/Graphics:Workflow#Rendering_setup for camera vs. render size)
Now just apply a texture and play around a little bit with bump-mapping (Materials->Map-To->Nor).
What you may also whish to do is to add some bumps to the mesh.
Just select the tile, go into edit mode (
Tab) and subdivide the surface a few times(
w -> Subdivide).
You can now grab some of the vertices and move them along the z-axis to give a bumpy look. What also helps is to turn on the proportional edit mode (
Alt-O). With this turned on the adjacent vertices to the one you're moving are also affected.
No offense, but you mentioned that you've got no blender experience. So I hope this might help a little bit.
