Hello
When I’m trying run my project I’m getting errors:

Because native memory runs out when trying to load a mesh.

3

Increase your direct memory size or load smaller objects.

4

How achieve that?

I mean, should I change this line in conf file:

default_options="--branding jmonkeyplatform -J-Xms512m -J-Xmx4096m -J-XX:PermSize=2024m -J-XX:MaxDirectMemorySize=4096m -J-Dsun.zip.disableMemoryMapping=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true"

or in Java panel?

In the properties panel of the project.

Okay I will check it up. Also, is there any way to force using LWJGL64.dll? I’m getting FileNotFoundException: C:\Users\me\Documents\TLT\lwjgl64.dll (Process can’t access file because it’s used by other process). Is it caused because I’m running project directly from JME3?
