- \n
- The UV Texture Editor<\/em> is where you can see the UVs of your model. They are similar to the vertices except they live in flat 2D space. The UVs determine the coordinates of a point n a texture map. In order to properly assign a texture to a model, The UVs need to be unfolded like a table cloth.<\/li>\n

Modifying UVs<\/h2>\n
It is important to prevent overlapping of UVs where it’s not wanted.
\nEx: A planar projection from the front of the model, the front and back UVs of the model are overlapping. Hence, if you changed the color of the character’s belly, the back would also change.<\/em><\/p>\nIn our examples, we made a planar projection on the side because our model is symmetrical on the X-axis. We run into a problem. The UVs of the arms are overlapping with the UVs of the belly and could cause unwanted results.<\/p>\n
UVs can be tweaked in the UV Texture Editor. Alter the UVs manually.<\/p>\n
- \n
- Select the Arm UVs\n
- \n
- – Select the body.<\/em><\/li>\n
- – In the UV Texture Editor: RMB<\/strong> over the body’s UVs and select UV<\/em><\/strong><\/li>\n
- This sets the selection to UVs, similar to when you RMB over a model and select Vertices.<\/em><\/li>\n

<\/a><\/li>\n- Note: The placement of the UVs does not need to be perfect since the arms will be the same color overall.<\/em><\/li>\n
- – Close the UV Texture Editor.<\/li>\n
- Note: Another technique is to cut the UVs and move the arm aside the rest of the body.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

3D Paint Tool<\/h2>\n
Create custom textures by painting a texture directly on a model in the viewport using the 3D paint tool. <\/em>Use the tool to outline areas to be painted in Photoshop or another software.<\/p>\n
Note: When working with the 3D Paint Tool, be sure to adjust the UVs to minimize stretching and overlapping.<\/em><\/p>\n
