Thank you for the tips, Larry. After a day of testing, and poking around, I realized I was using the 32 bit build of oiio. It worked without any issues when I switched to the 64 bit build.
Is there any way I can contribute back to the community? Below this line is just for sharing the information: The followings are the actual command I ran (in 32 bit build) and the return values in command prompt and pycharm. COMMAND oiiotool.exe --debug --runstats --info D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg --ch R D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg --ch G --chappend D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg --ch B --chappend D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Opacity.jpg --ch R --chappend --chnames R,G,B,A --resize 8192x8192 --compression lzw -d uint8 -o D:\lab\megascans\_output\plants_3d_ucokaamia\sourceimages\result.jpg OUTPUT FROM CMD Reading D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg : 8192 x 8192, 3 channel, uint8 jpeg Reading D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg D:\lab\megascans\plants_3d_ucokaamia\Textures\Atlas\tmjrbjiia_8K_Albedo.jpg : 8192 x 8192, 3 channel, uint8 jpeg This is really the end of the return values from cmd. It stopped without any error message or output data.
