Long compilation of the blueprints

Development Programming & Scripting Blueprint

Hi, i have installed 4.17 version and noticed long compilation of blueprints.
For example on 4.10-.4.16 versions, the compilation of the game mode takes about 3-5 seconds.
4.17 version, the compilation of the game mode takes about 12-15 seconds.

What is wrong ? I need to help

I have the same problem in v.4.17.1.

Very long time compilation of blueprints.

steps to reproduce the problem:

  1. Create empty project
  2. Create empty blueprint
  3. Place ~100 copies of this blueprint on scene
  4. Press “compile” in thes blueprint

Compilation will be long time (in my case 10-15 sec)

This is probably related to the new compilation manager. There appears to be an issue with it that causes very long compile times with some blueprints. It can be disabled in the project settings. I saw BPs that took 12kms to compile go down to 1k ms. Can’t seem to get anyone at epic to respond to this issue.

yes, you are right, i already solved this problem

Also if you have a specific BP that say 30 other BP’s reference you’ll notice that compiling that specific blueprint will take allot longer then the others.

Sometimes I noticed I can cut down a BP compile time by cleaning up my nodes . Stuff like getting a variables 50 times when you could get once and feed off the one.

my general rule is when your BP project starts getting large and complex expect your compile times to rise.
