I’ve been working with Unreal professionally for a few years now, both 3 and 4, and at one point I had a pretty comprehensive UE3 blog with some resources that even when they became outdated still had some significant traffic.
Blog will have tutorials, random developments, and marketplace reviews slowly added to it. YouTube channel will have just the video bits of the blog.
If you like what you read, great, if not, I’m sorry. Comment either way, or not, I’m a forum post, not a cop.
