I’m making an AR prograrm, previously I can package it successful, however after I add more candidate image, it can\t package any more
After a lot of trying, I found that if I set D_ARSessionConfig->Candidate Images to previous image data, can be package sussfully, new image data can not.
Meanwhile, change the texture of candidate image can aslo change it wether useable or not, that means the texture is the key
After change image file, change .jpg to .png, all can not change the image to can be use.
Finally, I find Compression Setting of the texture is the key!
TEXTURE of CANDIDATE IMAGE MUST SET TO USER INTERFACE 2D(RGBA)!!!
Then! This Image can be tracked!
