Been studying 3rd person camera and discovered a neat trick from Zelda
Walls blocking camera is commonly solved by moving the viewpoint closer. However when the wall is moved away, Link's camera doesn't immediately jump to its original position, instead only slowly recovers when there is user input.

It's VERY common for sync (blocking) loading BP nodes to slip into a project, making it hitch.
A project should have ZERO of those in their projects in my opinion.
Finding them can be a challenge, so I made a validator to catch them in BPs early 👇 #uetips

If you are using Visual Studio with Resharper or another tool replacing Intellisense:
Setting 'Disable Intellisense' to True is _not_ enough, you also need to set 'Disable Database' to True
This made VS sooooo much faster for me 😅

It's pretty common for folks to prototype spaces in Unreal using the default colour scheme and simply never change it. Often something more vibrant with stronger contrast is more helpful for readability and it takes about 30 seconds to tweak the colours for your style of game to help design. #UETips
