I was trying to use metal api to display 3D object and I followed this tutorial (http://metalbyexample.com/textures-and-samplers/) but when I tried to change the Object he use with my object it showed like a blockŲ I'm sorry I can't post an image, it's supposed to be an object for a foot.
I can understand if the object didn't fully display or any thing like this but it didn't have any features just a block.
Any help for this ?
