I would like to make simple java application to preview directx 11 textures, To preview directx 9 textures I used jme3 engine, but i don´t relly know if it support directx11 texture´s format like BC1_UNORM. Could I use that format in jme3 or I am going to need another way to preview that format in java?

Look at the table:
