Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Safe to upgrade?

I want to upgrade to the latest version. I'm currently running 4.16.2. I am seriously worried that projects I am working on will encounter problems after I've upgraded.

Simple question: Is it safe to upgrade or should I stay with 4.16.2?

Please someone provide some guidance with this.

Thanks

Ray

Never assume it's safe. Make a copy of your project just in case. Make a copy of your project at least once a day and back it up online. Thank me later.

Generally speaking, you want to update to a newer engine version if you are experiencing bugs that slow down or block your development. Or if you're after a newly introduced feature you need. QoL improvements might not be worthwhile.

Again, it all depends on how advanced your project is. It may work flawlessly; you may need to spend 10h debugging to make it work; it might be beyond saving. That's why you need a backup - worst case scenario is that you simply uninstall the newer version and continue with you old project.

The Compile Manager introduced around 4.16 or 4.17 complicated things a bit when upgrading.

Thanks. So basically there's no definitive answer or way of knowing in advance.

I back up my work regularly at the moment by zipping it up. Not had to "restore" as yet thankfully.

Thanks

As @Everynone said, make copy and try. I'm upgrading my project when new version is stable, from 4.14 or before I think, but always one version up only, from 4.16.2 to 4.19.1 can by risky, but when you work on copy only, why not. Some work for sure, I don't know your code, but for sure you will have a lot of work with materials, because shader model changed and materials from older version in short words are darker now, but not only.

Agreed. The bigger the jump the more things just get messed up. Dependencies and structs being the main culprits for me.
