I keep getting CRC errors when I try to package. Any idea what's causing this?

I’m working on a fresh source build of UE4 4.19.2 and running VS 2015

When I try to package I get this error:

PackagingResults: Error: PNG Error: IDAT: CRC error
PackagingResults: Error: IDAT: CRC error
PackagingResults: Warning: PNG decompression of source art failed
PackagingResults: Warning: Cannot retrieve source data for mip 0 of texture T_Checker_concrete_03_N

Any idea what could be causing this? Thanks, bros.

Figured it out. It was a corrupted PNG file. Redownloaded the file from the marketplace and packaging succeeded.

You use GIMP, right? I found GIMP causes that kind of corruption sometimes :slight_smile:
