We're back with Karan Shah's awesome tutorial on creating a low-poly T-Rex using Blender and Gimp. In the this module you'll learn how to Unwrap your model using Blender's built-in UV Mapping tools, bake an Ambient Occlusion map and finally how to create textures for your T-Rex using Gimp (or your image editing software of choice.)
Press 'Ctrl+TAB' and select 'Face' select mode. Mouse over any of the faces of leg and press 'L'. You'll see that only the group separated by the seam is selected (this only works with Face select mode.) If you press 'L' to select a group while in Vertex select mode, all connected vertices will be selected despite any of the seams. Hover over the head and press 'L' again to check. If you get any extra faces selected, then the seams are not properly closed. Re-check them from all views. Move you mouse over the selected group and press 'SHIFT+L' to deselect it.
The commands are:
Of course there are more commands to learn but these will do for now. To maximize the UV Editor, move the mouse over the UV Editor and press 'Ctrl+Up Arrow'. Press Ctrl+Up arrow to toggle back.
Select 'PNG' Format and decrease the 'Fill Opacity' to 0.00.
In the Materials Panel, scroll down to 'Options', and check 'Face Textures'.
