    Making a carving (Any skill level)

    Hey guys, this is my first Blender tutorial, so please bear with me if it’s got some issues and such. As far as I know, I’ve developed this technique myself; I couldn’t find anybody else with a tutorial like this. This tutorial is intended for anybody, from a newbie to a professional. I’ve done my best to make sure that a beginner can follow along, without making it too simplified for pros.
    __________________________________

    Okay, I’m going to show you how to create a realistic-looking carving in Blender using a picture. This technique is great if your image is not high enough quality for you or if using a bump map does not give good results.

    Before you start, pick out an image that you will use to turn into the carving into 3D. IMPORTANT: Choose an image that doesn’t have an insane amount of detail for your first try; this process takes a while, and the more detail is in the picture the harder it will be and the longer it will take.

    You may need to look on the internet or take a picture of a carving you like to find a good one. I’m using the picture below.



    Okay, so open up Blender, delete the default cube, and put your image in the background (View > Background Image).

    Create a plane, and delete all but one of the vertices. Go into top view (NUM 7). Put that one vertex on some line on your image (See below).



    Extrude that vertex (E) to trace that whole outline. Be sure to put a vertex wherever two lines intersect or touch. Also be sure to snap the vertices to the grid when you’re extruding them, you’re going to need to be able to snap other vertices to the same position; the grid is the simplest way. You don’t need to be perfect with the outline, just make it follow the path fairly well.



    Look at the picture to see what it should look like now. Note some of the vertices (circled in red) that are placed where two lines meet.

    Okay, now extrude more vertices to trace the rest of the picture. Use Remove Doubles (W > Remove Doubles) every once in a while to avoid confusion.

    When you think you’ve traced all of it, go into Object Mode (TAB) to make sure.



    Now, apply a subsurf modifier. (You DO need this now.) Go into the edit panel (F9) click the “Add Modifier” button, and click subsurf. You can use a level 1 or 2 for now. You also may want to click the “Optimal Draw” button so it’s easier to see what you’re doing.

    Okay, go back into Edit Mode (TAB) so we can start the main work. This is the part that will probably take you the longest. Choose a separate section (a section of the picture that is completely enclosed) and select all of the vertices in that section. This part must be done one section at a time. Once you have the vertices selected, go into front or side view (NUM 1 or NUM 3) and extrude (E). Move it in the Z direction to the level of thickness that you want your carving to be (in my example, I moved it .1 in the Z direction, meaning that my carving won’t be incredibly thick).



    Now you have to start making faces. Select any 3 or 4 vertices that are near each other on the top layer, and create a face (F). I recommend that you use mostly squares, with a few triangles where necessary. Do this to complete an entire section.



    Now move onto the next section. Make sure to extrude all of the vertices, even the ones that were used in the last section. Extruding those vertices twice gives it the effect of depth.

    Continue to do this for the whole model. Sometimes, a section will have some vertices that are used more than once in the same section. If you do the whole section all at once, the depth effect will not appear. You basically have to do it in parts. (It’s hard to explain, look at the pictures.)



    Here is the first half of this part.



    Basically just extrude the parts as if they were separate sections. Now it’s almost done, except it’s got that weird crack. Go into Wireframe Mode (Z) or click the “limit selection to visible” button (the gray box) and select the vertices where the crack is. To be sure that you will select all of the vertices there, use box select (B). Now hit W > Remove Doubles. If you selected all of the vertices that were there, the crack should be gone, in which case you can finish up that section.



    If you want you can now TAB out of Edit Mode and into Object Mode, to see how you’ve done so far. If you want to, hit Set Smooth in the Edit panel (F9). You will most likely have flipped normals, so TAB back into Edit Mode, select all, (A > A if something is selected or just A if nothing is selected,) and hit Ctrl-N to recalculate the normals.



    Now go ahead and finish up your model.

    Once you’re done with the mesh, you can move on to the materials. I recommend using a wood texture (something that looks like a wood that someone would use to carve) mapped flat onto the object. Go into the Shading panel (F5) and click the Add New button to create a new material. Leave these settings for now and go to the Texture panel (F6). Click ADD NEW to create a new texture, and choose Image from the menu (or if you have no good wood images, choose Wood and set that to how you like it). Load the image, set it to Clip (or Repeat if you need it to repeat, and if the texture can tile). Now go back to the Materials panel, and set the reflection, specularity, and hardness. Add a little bit of Ray Mirror if you have a shiny wood.

    There you go! That’s pretty much it. If you want, you can edit the mesh to add depth to the carving or crease the edges (Shift-E) to make it look how you want.




    Common Problems

    One problem I’ve noticed is a weird effect that basically looks as if parts of the object have been Set Solid. You can fix this by turning up the Subsurf.




    Another problem sometimes happens (but not often) where you may end up selecting the wrong vertices when you create a face. If this happens, (it is fairly obvious,) hit undo (U in Edit Mode or Ctrl-Z for everything). Go into wireframe view (Z) or hit the “limit selection to visible” button and select the vertices you want to create a face out of (but don’t create a face yet). Grab them (G) and move them around. Look at the mesh to see if you’ve grabbed the vertices you want. Deselect the ones you don’t want (B > RMB) and try to select them again. Do this until you’ve got the right ones.

    If you’re going need to select those vertices for more than one face, grab the ones you don’t want (use the same technique as above) and move them out of the way. Be sure to snap them to the grid, because you’re going to want to move them back to the exact same place once you’re done.

    A third mistake I’ve made a few times is removing doubles with more what I need selected. You can tell what happens if you remove doubles from the whole mesh; essentially all of the lines go away. Just hit undo if this happens. You must remember, the duplicate vertices give the cut effect. Do not hit Remove Doubles unless you must, because it will do this if you use it in the wrong area.



    That’s it! Hope that you liked it.

    Thanks for doing this. I like the way it looks and will certainly try it.

    Rhis is very useful technique indeed, if you have nerves and patience. I made my Opeth-statue using that same technique:

    This is a very interesting tutorial.

    Thanks so much. I learn something new here..

    Nice, but you can use the Curve/Array modifier combo (it's in this forum) in order to trace your outline, which would be smoother, require fewer extrusions, and also allows you to skip most of the "face making" steps.

    Theoretically xD

    Why not use Displace modifier to raise the relief version of the Art work, then cut off the bottom of the mesh?

    You could also create the faces with the object still in the flat portion of the modelling. Then extrude the individual faces you need to and use the Bevel modifier.
