Found the problem. Accidentally left OptiFine in the mods folder. Thanks for the help.

Hi! I'm trying to make a server for my modpack and I want to make it run as efficiently and smoothly as possible. So, I wanted to use these parameters for it: I ran the server with these and it worked fine, but it crashes at the end right before it generates the map. It states this: Anybody know why and how I can fix this? Thanks for reading.

I just looked through both FPS Plus and OptiLeaves. It looks like it can only be put into the Forge.jar folder. They modify parts of Forge itself for rendering and extra performance.

Hey, again. I'm creating my modpack and I would like to use a modified minecraft.jar that uses FPS Plus+, Optileaves, and other performace-enhancing mods that directly modify the forge jar. I've tried to name the jar minecraft.jar and make the launcher download that instead of downloading the normal minecraft.jar. Is there an option to do this? Thanks for reading.

Thanks for the help! I've been trying to find out how to do it for so long.

Hey, guys! I'm having a bit of trouble here with the Tekkit launcher. So, I develop modpacks using the default minecraft launcher with my own settings and tweaks within the JVM arguments and such to get the best performance. My only problem is: I don't know how to add JVM arguments into the technic launcher. I know it has to be in a file called "version.json" but I don't know what exact things/parameters I need to put in before I put it all of my arguments. Thanks for reading.
