In this Blender 2.5 Video Mini-tutorial, I go over how to use the Array Modifier, and then go on to bake the Ambient Occlusion and Tangent Normals.

Cool, I can picture the dragon roaring from the top of this tower.

Love your tutorials.
Thought you might want to know that the “hide behinds” are called crenelations.
Can’t wait till you get to the rigging part of the dragon!
Actually the “hide behinds” are called merlons, the crenels are the space between the merlon.
I had to look it up, cause I thought it was called a parapet.

The word you are looking for is crenellation
Regarding the dragon, I’ve found that it it better to rig the wing using a soft body than the cloth, here is a vid with a bat wing I’ve rigged if your interested:

to solve the problem of the center you must shift+E the vertex of the center… isnt it the problem?
Anyway, great idea that of the arrays+rotations!!!
Nice tutorial.
ps.A little tip: to merge windows click and drag right or up the upper right corner. To split them just drag down or left.
Why don’t you just use “limit selection to visible” button when you are selecting?
In all of your tutorials you waste so much time selecting the wrong thing.
After some messing around, I found that the clay and inflate brushes seem to be the best for what you were trying to achieve.
Also, if you set the stroke method (sculpt tool menu -> stroke) to ‘anchored’ then the brush won’t move but it will allow you to sculpt with textures much easier.
One more thing: if you download a picture of bricks and turn it into a texture then you can get a nice brick effect. It is also rather easy to make an extremely ugly brick effect.
What’s the best way to turn a brick pic into a texture? I’m pretty dumb on that subject…
The way I did it was to download pictures of brick walls from CGTextures.com.
I then used GIMP to turn the images into grey-scale images (not entirely necessary). (Colours menu > Desaturate)
In the texture panel make a new texture click the ‘Brush’ button. Select image/movie as the texture type and navigate to the image. You can then select the texture as a brush texture in the sculpt tool shelf under ‘Texture’.
I think the sculpt tutorial that Jonathan posted recently demonstrates textures as brushes.
You can adjust the texture size in sculpt menu. (Sculpt Tool Shelf > Texture > Size X: Y: Z:)
Just a tip: to make sharp edges without adding edge-loops you can use creases, type ctrl+e and choose “edge crease” and move your mouse to sharp the edge. If you want you can also change the value in the transform panel in the “n” tool bar…
The only problem with using the Crease function is that it tends to created less-smooth or jagged edges. If you are trying to maintain a lower polycount then using both techniques together can create good results.

Creases suxxx..
The problem you have quite at the beginning with the array modifier is, because the array modifier doesn’t have an option to automerge when the verts are close together, which the mirror one has.
If you used the mirror modifier and turned off that option, you’d get the same result (except with four, rather than six parts)
You don’t need to merge. The verts are perfectly atop each other. All you gottta do is remove doubles
oh, ok… lol, and a second later you tick the merge box, I never used before and everything works. Haha
hmmm… do compositing nodes work with the sculptmode?
Because you could try to use a bricktile texture, overlay it with a cloud texture and then use that as your brush.
That way, you automatically have that brick look to it…
Btw: When you did the AO map, you had it set on multiply and it was all based on the one lightsource. It would have been better to switch that lamp off and have AO on add.
Or, as you did earlier, use Environment light and AO on multiply.
And in the end, you have kind of a double AO, due to the map and the calculated AO on top of that
It’s quite a nice tutorial.
Nice tutorial. I like your use of sculpt mode to bake in your texture maps. Can’t wait for the dragon integration!
I think it would be a good idea to try and re-sculpt the tower in 2.5 beta
@ 12:57 you marked that edge sharp instead of a seam.Thats why the bottom didn’t unwrap.Very good series can’t wait till the final.!!!
Messing with the creasing around the crenellations would’ve definitely helped around the outside of the tower, though, as it looks very polygonal due to the close edges running down the entire wall…
Hi there,
I’ve seen this vid ten times, but i don’t know what i’m doing wrong
I have two problems: 1)”No image found to bake to” 2)Windows crit error and Blender goes down during the baking
PS: I apologize for my english
Hi, I am not sure what would be causing the critical error without more information. However, the “No Image to Bake to” is cause by no image being applied to your models UVs. If you go to the UV imaged editor and apply and image while in edit mode it should work.
-Jonathan
Thank you. It still falls down, but i can make UV map now
Since switching to the 2.5 builds of Blender I have not been able to use the brush select anymore(b-twice) at 13:13 he uses it to select the vertices at base of the tower…. I just now downloaded 2.54 am I doing something wrong?
The brush select hotkey has been moved to “C”. It’s easy to remember if you think of “circle select.”
-Jonathan
can you make a tutorials that shows you how to create uv maping that you can work on photo shop
Hi Guys
I keep trying to do this tutorial but come across the same problem.
I create the tower, apply the array etc and make the full tower using the array. For some reason though the segments are not connected. If I use scale it will scale them individually – therefore it breaks – any idea why? or what im not doing?
Have you enabled “Merge” and “Merge Last” ?
-Jonathan
Thanks – Sorted it!
When scaling the top of the tower in, I selected the 3d Curser but didnt put it to the centre of my tower, therefore it messed up
Thanks for the help
Crenellations… (hidebehinds)
