This is not always easy to find the right files to create decorations for minifigures. Therefore I decided to create this topic to give more advice and track any changes that will be made.

All uv maps are available on my public drive.

Heads
Three moulds are available:
1. The original version with a solid stud. It has been in use until the mid 1980s. The reference on Bricklink starts by 3626a.
2. The next version with an open stud blocked by a 3-branch star. This version has been retired from LEGO sets in the early 2010s. The reference on Bricklink starts by 3626b.
3. The current version with a hollow stud. The reference on Bricklink starts by 3626c.

Image

For the original version, only one uv map is available. The name is 3626v3uv. This is a projection from the front and the back. At that time, heads were pretty simple and never printed all around. Make sure that you do not draw outside of the red areas otherwise, the decoration will leak on the edges.

Image

For the two most recent versions, the same uv maps are also available. the names are 3626v2uv2 (hollow stud) and 3626uv3 (blocked open stud). In addition, a second version has been made to allow the creation of heads printed all around. The names are 3626UV2 (blocked open stud) and 3626v2uv (hollow stud). This is an unwrapped version with a seam on the right hand side. This one is more complicated to use as you have to imagine a flattened cylinder.

Image

The best solution when scaling and positioning the decoration on any of the uv maps is to use the top and bottom mould lines as references.

File resolution shall be identical to the uv map png file available on the mecabricks public drive.

Upper Body
The elements of the upper body assembly that can be decorated include the torso and the two arms. Most recent arms can be dual moulded however the shape is identical and therefore they do not have separate uv maps.

Torso
The uv map currently in use for the torso is 3814uv.

Image

The back and front shapes represent the flat areas and do not include the bevels. This is something to keep in mind when scaling and locating the decoration. The neck marker can only be black (MB #010101) or white (MB #f4f4f4) or not present at all like on the collectable minifigures.

Arms
Two uv maps are available for each arm. The first version 3818v2uv and 3819v2uv is a projection from the side. This is the easiest to use but it is not possible to recreate the most intricate designs. For these cases, there is another version 3818v2uv2 and 3819v2uv2.

For 3818v2uv and 3819v2uv, ensure that you do not draw outside of the red area. If you do so, the decoration will leak on the edges.

Image

The second version named 3818v2uv2 and 3819v2uv2 is more complicated to handle. You may have to use texture painting in your preferred 3D package to ensure that the decoration is properly located, scaled and not skewed.

Lower Body
All three elements of the lower body assembly can be decorated including the hip, right leg and left leg.

Hip
The uv map currently in use for the hip element is 3815uv3.

Image

Legs
Uv maps for common legs are named 3816uv4 and 3817uv4. LEGO only prints on the front and external side. These two areas are orthogonal projections and therefore you shall keep your decoration within the limits.

Image

Dual-moulded legs are slightly different from their single material siblings and therefore they have dedicated meshes and uv maps called 20932uv2 and 20926uv2. I created special templates for Photoshop and Gimp that you shall use to ensure everybody has the same border between both materials.

Image

They are available here for download:

Thank you for this, it is really helpful. I had been having a lot of trouble with the edges of the printed areas of parts, and with the location of the different materials for dual moulded parts, and the templates look like they will be really useful.

How to use custom decorations?

@Andruha656, you aren’t able to put custom decorations directly into the workshop, however you can still use them by exporting the model to blender or another 3D program and replacing the mecabricks decoration with PNG files of your own.
