Thank you Dave!
I've already tried using the Fish Fossil files provided by CHI and it works fine with that (also the visualization with the rti-reader).
When I try with my images it doesn't work: with the "manually changed" .jpg to .jpeg the open folder button crash (glitch, meaning it doesn't work; it doesn't upload the images). With the initial .jpg files I use (I do not work with .raw, and that should be another question, but not now..) the folder charge, than ball detection, highlight detection, than also cropping but it stops during executing, showing me that unknown error (unknow file format: .JPG, in the right side of the window). When using .jpg files, it load my images, ball detection, highlight detection, executing, it stop with the error, but it creates the assembly folder (with inside two .lp files and three .jpg files), it also create a .xml file in my folder.
So I can't understand why this happens.
1- I've never succesful created a ptm, (only the fish fossil with the files already provided)
2- I'm running Windows 10 Home (x64), with 8gb Ram and a i5 processor.
3- The size of my pictures is 4608x3072 (rti-builder final step) but I also tried resing it to 3000x2000. What do you mean for "source"?
Thanks
