Thanks to all who replied. I did the EDR Bob, as soon as I installed the upgrade and although there was about 800 errors I'm now down to the last 53, most of which are .tga files as above. I have tried PE's Images2TGA but couldn't get a result so activerail, perhaps you would be kind enough to give me a breakdown of how you did it. PEV was one of the contributors to the 2012 thread on the same subject and didn't mention using his program so I'm keen to see how you did it. On that 2012 thread referred to above by Neil, there are two valuable comments in Post #9 by an N3V moderator who said to either eliminate the .tga file [How? If I just delete it, wont that bring up more errors?] or reduce the size of the file. Has anyone reduced the size of a .tga fie in MSPaint and exported it back to the asset folder? I have found how to reduce the size in MS Paint but cannot get the file back into the asset folder. Any help out there? I don.t want to just commit the warnings because it apparently causes a performance hit and this problem is likely to get much worse with T2 so need learn how to fix them. Cheers
