:DThank you very much for your answer. Regarding the software version, the author of the software seems to have recently updated the version, but I have used the same version of the wallworm, regardless of whether I used the previous version or the latest version. I know that the free version does not automatically recognize the material file, so I have used VTFEdit to batch convert the material files into the TGA format, but it is still useless. Come here for help, the author seems to be very busy, then I will wait quietly, thank you for your response to my question ^_^
