The following Tutorial helps you create a texture palette inside ARki app to showcase material options.
From ARki 7.0 you can import several textures into each scene to showcase material options
How to create a material palette
1: Select Material button and then start selecting the meshes to texture
2: select textures from the ARki library to use on your layer.
3: Drag and drop library textures onto the layer materials to start texturing the mesh
4: To add your own textures Import JPG or PNG files below 2mb, smaller than 2048 pixels wide.
* For best performance UVW map your textures on the mesh first, inside the 3d software you have used to create the model. ARki will read the UVW map information from the existing mesh to determine texture sizes and tiling.
