Warning: Be sure to scan all the downloaded files with your Antivirus and if there is an executable or installer file, make sure to have your antivirus active and open in the background while installing or running the app. Some of the materials posted here are downloaded from CGPeers, So they could potentially have something injected in them.
We always ask bloggers to scan all the files before publishing the posts, but sometimes it's hard to detect all these things, so if you found anything suspicious (Not false positive, Generic, Patcher, Riskware and Heuristic results, most patches could get false flags like that by some Antivirus companies.) be sure to post comments with the file name and a VirusTotal report result link or the file MD5 Hash (higher than 30% overall positive result). Thank you.
Thank you very much. There are losts of material for Unity but no so much for UE4.
