Hi @fanmengcheng, the error message indicates that Unity cannot find the libvhacd.dll. Could you double-check if the libvhacd.dll is in the right folder? If so, please double-check the file's content or the file size to make sure it is not an empty file. Please let us know if the DLL is correctly downloaded or not?
