I made a test today. I set max_nexus to 150mb on WED. If I compiled the main script on SED, I only got max_nexus 40mb (default). However, if I compiled the level on WED, I got max_nexus 150mb.
Here is the problem, what if I have many levels with high nexuses, I need to export my project from SED. How can I change max_nexus by code on SED?
