Every time I do anything (click anywhere in the content browser, compile a BP, click anywhere in a BP Graph) I get the message “LogRenderTargetPool:Warning: r.RenderTargetPoolMin exceeded 432/400 MB (ok in editor, bad on fixed memory platform)” in the Output log (which I always have opened on my third monitor). I have no idea what this means, but it’s annoying. ---

Hello - Recently we lowered the level from warning to something lower. It’s just good to know that the pool size is exceeding and it might cause minor stalls and a lot of video memory. You can run “vis” in the Output log to see what is allocated (Might be the screen resolution or many ReflectionCaptureActors). With “r.RenderTargetPoolMin=500” in the consolevariables.ini (or in console "r.RenderTargetPoolMin 500 ") you could prevent the printout. Thank You Eric Ketchum ---

Thanks! But if I run “vis”, it says only 100/400MB is allocated (and directly after the vis output I get the warning mentioned above again). I don’t use any ReflectionCaptureActors and the Screen Resolution in the Editor is not really high, I have a 1080p screen. I have one SceneCapture2D in my Level which renders to a RenderTarget2D with a resolution of 2048x2048, but this (hopefully) does not allocate 432MB of VRAM! ---

This is the output I get from “vis”: link text ---

Hi - No that one screen capture should not, can I ask what video card and driver you are running currently? Also, does resetting the r.RenderTargetPoolMin to 500 still produce the warning in your logs? Thank You Eric Ketchum ---

I have a AMD Radeon HD 7850 with Catalyst 14.4 driver. I know it’s one year old, but the newer versions are not compatible with some software. After setting the r.RenderTargetPoolMin to 500 I don’t get the warnings in the log. ---

Hi John - Instead of just the “vis” command, try using the “visRT” command, a window should pop up and see if the total there is at 432. visRT breaks down all render targets in the engine currently running. Let me know - Eric Ketchum ---

Thanks! With visRT I indeed see all the RenderTargets and it says 408MB allocated… It seems the translucent Water Material from the Epic Water Examples is using a lot of RAM.

Hi John - Thank you for the report of the crash. I have entered a report, UE-14237, for reference, and will let you know as soon as we have a successful fix for the issue. Thank You Again - Eric Ketchum ---

Got the same error message this day. It appears every time when i exit PIE or Standalone play. Its too strange, because i didn’t added any real actors content to the levels at all - i am currently only working with Blueprints (for creating Menus). The only visuals i have added - clickable boxes and their texts for menus. But even yesterday that error was not present. What i did today is just began a new menu for Options/Setting (actually duplicated my previously created Main Menu).
