TUTORIAL T13 Make a Necklace.

As follows, let's make the necklace fit for the body.

When making a necklace from 1 Prim, it is difficult to make it what was exactly used as the body.
Then, let's read the OBJ file of an avatar into UTSUSHI and make the background image file used by TATARA.

The step which makes a necklace is as follows.
1) Extract only a group needed of ObjCut for the OBJ file of an avatar.
2) Read the extracted OBJ file into UTSUSHI and make the background image used by TATARA.
3) Boot TATARA and do initial setting of a sculpted prim.
4) Make a necklace thin in ROKURO mode.
5) Read the background image which was changed to TSUCHI mode and made from 2.
6) Adjust the position of a necklace in the edit display which looked at the body from the front.
7) Adjust arrangement of a necklace in the edit display which looked at the body from the top.
8) Make a necklace fit the body in the edit display which looked at the body from the side.

Let's make a necklace.

Let's download the OBJ file of an avatar from Second Life Wiki first.
The file is in https://wiki.secondlife.com/wiki/Creation_Portal.

Please click the link underlined in red, and you will get the avatar_mesh.zip file.

Upzip it, you get an OBJ file.

Let's extract a portion needed in order to make a necklace from ObjCut.

You can download ObjCut from the following web pages.

Let's boot ObjCut and check a setup.
Choose Group Option of a "Divided by" group and close ObjCut.

Drop SL_Female.obj with the icon of ObjCut.

Then, the list of the groups contained in SL_Female.obj is displayed.
Check TextureGroup_Up, chest, TextureGroup_Up lCollar, TextureGroup_Up neck, TextureGroup_Up rCollar and click the OK button.

Then, SL_Female_Selected.obj is outputted.

You can get UTSUSHI from the following website. http://kanae.net/secondlife/utsushi.html
It is freeware.

Drop SL_Female_Selected.obj with UTSUSHI.

Then, UTUSHI starts and the following forms are displayed.
Click "4" button of a View group and set X of a Rotate group to 90.

Then, the bodily front is displayed as follows. The necklace to make is shown by the red line.
In order to cut off a portion needed as a background, drag two red lines on either side and two up-and-down blue lines.

Arrange four lines, as shown in the following figure.

Click "5" button of a View group and display the bodily side.
Similarly, drag two green lines on either side.

Arrange them, as shown in the following figure.

Choose Save Image on the File menu and save a background image.

The background image used in the TSUCHI mode of TATARA supports the image displayed with 0-4-3 button of the View group of UTSUSHI.

Since these are saved collectively, choose 3 Images (PNG) of the dialog which saves a file.

Then, they are collectively saved by the following image. If it is read in the TSUCHI mode of TATARA, it will be automatically distributed and displayed on three edit displays.

* TATARA judges whether it divides into three edit displays with the aspect ratio of the image of a background image. You can make this image with a paint tool.

Let's read a background image into TATATA and make a necklace.

Boot TATARA and choose New-Torus-128x8 on the File menu.

In order to modify smoothly, choose None of Grid on the View menu.

Make the section of Taurus small in a size suitable as a necklace in ROKURO mode.
Choose all and drag a lower right control point.

Then, it is displayed as follows. This is the thickness of a necklace.

Choose a TSUCHI tab and change edit mode.

Choose Load Background on the View menu and specify the created background image.

Then, an image can distribute to each edit display in TSUCHI mode as follows. Let's make a necklace fit the body.

Click the XZ button in the lower right of an edit pane, and display the bodily front.

Choose all the necklaces and a necklace should move it to the height which the shoulder touches.

Drag the control point which is in the right side so that a necklace may be applied to the place where the shoulder became depressed, and reduce a necklace.

Left side should also drag the control point which is in the left side similarly, and should reduce a necklace.
Make a central control point symmetrical with a blue line in layers.

Click the XY button of an edit pane and display the bodily upper part.

Check how the necklace is applied to the shoulder.
Drag the control point in a central lower end, and expand ahead.

It is as follows.

Click YZ of an edit pane and display the bodily side.

Choose the portion which covers the back.

In order to choose correctly, it is good to use Bitmap mode.

The control point which shows the rotational center is displayed in the center of the selection range.
On this control point, cursor becomes an arrow. Drag this control point to the right end of the selection range.

Cursor becomes a rotational form from the right end of the selection range in the place from which a few was separated.
Then, drag it, rotate the selection range and put a necklace on the body.

Choose the portion bent similarly, the rotational center is moved to a left end and rotate it, and as shown in the following figure, also put the breast side on the body.

It is good to carry out expansion reduction of the selection range, and to adjust length.

If the curved area is rough, you can smooth it.
First, adjust the degree of Smooth by setup.

And choose a portion to smooth and choose Smooth from the pop up menu which right-clicks an edit display and is displayed.

Choose Maximize on the Edit menu and maximize a necklace.

Choose Setup on the File menu and check the option of preservation.
Set TGA Save Size to 64x64, check Copy Protection by transparent, and click the OK button.

Choose Save on the File menu and save a Sculpt-Map file.

Let's upload a necklace to in-world.

When you upload a sculpt-map file at a second life, please be sure to use Upload Image on the File menu. It costs 10L$ to upload one Sculpt-Map file.

And check it by preview and check Use lossless compression.

A yellow portion exists because the sculpted prim of Taurus is displayed by sphere.

If you apply scalp prim, set Stiching type to Torus.

Then, the film currently displayed as the preview disappears.

Please rotate Prim, because the sculpted prim made from TATARA is arranged upside down.

Take Prim with whom a setup was able to be managed and attach to Spine from your inventory.

And please adjust a position.

The necklace was completed.
