 Before you put your file in the generator, you want to make sure your images are of high quality. Make sure it's at a .tga file with 32 resolution. For the trace generator to work, click on the open floating file chooser and select the 2D image you want the program to trace. This will import your 2D image onto the program, but it still needs to be traced itself. So click on the arrow next to the tracer model and select the 2D image you put in from the Put Image file. You can select whether you want you pop up to have a fold or cut out type on and can adjust the paper thickness. When you are satisfied with what you have, select where what folder you would like to put your output file and the fileout name.fbx. Then just click Render FBX and  you have your FBX file!

In unreal, import your FBX file. Make sure you check import texture, then make your texture into a material. Then put the material you just created on your static mesh that you imported and Voila!
