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"

Print to log uses all my memory. Can I stop it?

When playing a project in the viewport, if you use print to log to monitor stuff in your project and have the log tab active instead of the component browser then all the memory in my computer gets used up until the project runs like a dog or crashes.

I have attached a screen grab of this happening (from task manager ). I have labelled what happened and when.

Is there either 1. A way to limit the total memory used 2. An altenative way to view live variables that does not involve creating widgets. Print to log works perfectly for live monitoring during testing except for this effect.

Is it a bug or a feature?

p.s. when I start the project playing I do not touch the keyboard or mouse. nothing is happening. All that is happening is print to log.

I have the same problem in 4.16.3, the engine just froze when I tried to open the Log Tab, in the Task-Manager of Windows I could only observ how the Ram and the Swap file slowly filled up, in the end Windows killed UE4 after ~90 GB were used... my poor SSD. I am currently logging Projectiles on Tick for Debugging purposes but I am confused how this Text can cause such a big memory impact.
