--- title: Removing Body Boundaries slug: studio-guide/removing-body-boundaries docTags: createdAt: 2024-09-02T08:34:13.133Z --- # STEP 1 : Preparations Before creating an item, download the required file ([Female\_Torso.fbx](docId\:ctCJwcYcqFub-BJhurQlQ)). Import the downloaded file and the created clothing object in Maya. - The Female\_Torso\_V and guide\_mannequin provided in the Female\_Torso.fbx file are provided in an A-pose. ![2000](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-IUdnOZsqwpMuE4XS8E-0F-20240904-102324.png) Combine the Female\_Torso\_V and the created clothing object into one object. - The material name of the Female\_Torso\_V must be skin. :::hint{type="success"} 👍 Before combining, it is best if you remove the parts where the model overlaps and hides each other. ::: ![2892](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-BgdwCowNlnheT-QQiYnOy-20240904-102324.png) Import the downloaded [creatorBaseSet\_ZEPETO](docId\:ctCJwcYcqFub-BJhurQlQ) and edit the joints to be in the A-pose. - Modify the rotateZ values of shoulder\_L and shoulder\_R to -7.5 and the upperArm\_L and upperArm\_R to -40 ::Image[]{src="https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-uFR74S2rsEDvpTUQrzDrG-20240904-102324.png" size="82" width="2000" height="1097" position="center" alt="2000" showCaption="false"} # STEP 2 : Removing the body boundary Select the necessary joints and do bindSkin. :::hint{type="info"} 📘 Please refer to the following guide [3D Rigging - Clothing](docId\:tNVbfwpxKqNbWgDq8VwCI) ::: ![2000](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-7OgqD1NJor0NSrBNt42QW-20240904-102324.png) Copy the mask weight value to Female\_Top and make sure that the weight value on the end of the Female\_Torso is the same as that of the mask. :::hint{type="success"} 👍 When doing Copy Skin Weights, make sure the pelvis value is set as translateZ 0.001 before you copy. ::: ![1654](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-BWKWFyVOwfqqcrgaEJgBm-20240904-102324.png) Paint the vertex of the mask that overlap the Female\_Torso black (0). Leave the other parts white (1). ![1399](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-97I8ymJDuweoFUNNMO60l-20240904-102324.png) When this process has been finished, do unBindSkin the mask to remove the weights and clear the history. ![3161](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-GP5CkT0OmI8vl-2uWmvCt-20240904-102324.jpg) Select the created Female\_TOP, mask, and joints. Then select export. ![1013](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-nygUxzQ4haNRlRcPOQrNP-20240904-102324.png) Apply the converted costume in Unity and make changes to the deformation values to check if the parts connecting the Female\_Torso to the baseBody such as the neck and arms appear smooth. :::hint{type="danger"} **❗️ caution** If the shading is severed or the mesh is not joined, this can be a cause of rejection during reviews. ::: ![1600](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-q_fBsS3VWs94x0JhiCvcm-20240904-102324.png) :::hint{type="success"} 👍 Keep to a few simple rules when using the female\_Torso and you can modify it into the shape that you want. - Do not modify the end of the Female\_Torso which touches the base body. - Because the female\_Torso has been modified from the base body, the UV is the same as the base body. Make sure not to modify this UV. Modifying it will result in a subtle color difference in the boundary between the base body and the female\_Torso. ::: ![1056](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-WRM_s7IxSVp9z7QFE8u14-20240904-102324.jpg) ![1471](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-VjrORFZOS5nTdyHUmcGGx-20240904-102324.jpg) # STEP 3 : Precautions If the female\_Torso and the normal of the base body are not aligned, a line may appear in the boundary. ![1554](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-A2dhSiqsR-A-wBjl4Mpiq-20240904-102324.jpg) The normal direction of the female\_Torso and the base body can be viewed by clicking Display > Polygons > Vertex Normals. In this case, you can import the Female\_Torso.fbx again and change out just the body part, or overwrite the normals of the vertex along the boundary with the normals of the base body vertex to fix the issue. ![2366](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-0iOnEyOHxeIF-RT7CmXPh-20240904-102324.jpg) Select the boundary area and the vertex of the row immediately below it. Then create set 1 by clicking Create > Sets > Set. ![2000](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-ooaEn-9paN8KhSupATKBS-20240904-102324.jpg) Select the mask and set 1 in order. Then select and apply Mesh>Transfer Attributes (options). ![2000](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-88SwHea73iBQEz1bBj7bO-20240904-102324.jpg) Select Female\_TOP and mask, and remove unnecessary information from Edit>Delete by Type>History. - Delete set 1 as well which is no longer in use. ![2000](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-C9MEb6laHIXbqiqb7jeZy-20240904-102324.jpg) A line appears because just below the boundary, the vertex normal becomes disconnected. Select this edge and apply Soften Edge to it. ![1814](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-MCitPbUJRyefvXOT0v838-20240904-102324.jpg) Checking the vertex normal again will show you that the vertex normal of the boundary area now matches the other areas. Rig with this resulting object again. ![2215](https://api.archbee.com/api/optimize/fCt3n1oCa8rgNJ8fw9I2N-MlnXMmTu6aA1WjB8UC7Xy-20240904-102324.jpg)
