[Permgen space problem]

I found it was pretty easy to unzip the launcher jar file, use jd-gui to decompile org.spoutcraft.launcher.Main and save the source to Main.java, then add a line such as

  params.add("-XX:MaxPermSize=128m");

in the reboot method. Then recompile using jdk 1.6 from the top level of the folder the jar file was unzipped into.

e.g. javac org/spoutcraft/launcher/Main.java

I'd post a jar file but that's against forum rules without admin permission. Hopefully this tip will hold people over until they release the new launcher.

[Permgen space problem]

Love to know the answer to this question. I ended up grabbing the code for the technic launcher off of git hub and was going to mod in permgen but it seems that github is hosting a brand spanking new launcher that does custom modpacks completely differently.

[Sideway textures on IC2 blocks]

The page posted by Woolz shows v220 as the current build version, which turned out to be unstable (clientside) for me. I ended up searching through the change history from the jenkins build log at http://ic2api.player.to:8080 and it looks like this specific issue is fixed at v209. Any version at or after 209 that is stable for you should work.
