jmemory.jar helps when you have problems with jEveAssets running out of memory

First make sure you're using the 64bit version of Java.
If you're not sure if you have 32 or 64bit, follow solution 2

1. Close all instances of jEveAssets
2. Double click on jmemory.jar
3. Wait for jEveAssets to load, then exit it again (if it crash before you can exit it, that is fine)
4. The file jmemory.properties should now have been created
5. Open jmemory.properties with Notepad (or another text editor of your choice)
   
   1. Open in Windows: Right click jmemory.properties select Open with then select Notepad
      
6. When you open the file it will look something like this:

   jmemory.properties

   xmx=1g

7. Replace the text xmx=1g with xmx=4g
8. Save the file
9. Now start jEveAssets again by double click on jmemory.jar
10. Did that fix the memory problems?
    1. If yes, then continue to use jmemory.jar to run jEveAssets (instead of jeveassets.jar)
    2. If not, repeat from step 5, but replace the text with xmx=5g, then xmx=6g etc. until you do not run out of memory.
       Note: you need to restart jEveAssets (with jmemory.jar) for the changes in jmemory.properties to take effect
