can i add optifine mod in mcreator?

Put the downloaded Optifine file here: MCreator161\forge\run\mods

@Nuparu00 I just tried that with the latest version of MCreator 1.7.5 and Minecraft crashes immediately after opening. It doesn't crash when Optifine isn't in the folder. In which version of MCreator has it worked for you?

I think its the test envirment only I know I used my mods with opterfine before

@#4 Did you use them together within the MCreator test environment or in normal Minecraft? I find the MCreator test environment to be extremely laggy and nearly unplayable, so I'd like to be able to somehow add Optifine.

you most likely need more RAM in your PC, as my Test Environment runs fine, i have a 4GB RAM card and it runs pretty good without optifine, but optifine doesn't sound half bad

@#5 According to my system settings page, I also have 4 GB of RAM. Would it then be that I need to let Minecraft/MCreator use more of it? I'm not sure how to do that.

@#5.1 i have no idea, can you even enter minecraft? does it crash upon entering the world? or just crash as soon as Optifine loads?

@#5.1.1 When I try to open the MCreator client test environment with 1.11.2 Optifine installed in MCreator175>forge>run>mods, it works normally until the Minecraft menu screen (singleplayer, multiplayer, etc.) pops up, and then that window crashes pretty much as soon as I can see the menu. So I can't actually press and of the buttons to play singleplayer etc. After it crashes, this box pops up: https://snag.gy/QwlI5B.jpg

I noticed there are some references to Optifine in the Console there, but I have no idea what they mean.

@#6 well... it seems like as SOON as the game opens its game window to load forge more, it crashes, try lowering/highering the amount of RAM MCreator uses, maybe that will make a difference

@#6.1 Okay, do you know how to do that?

go onto MCreator, go into Preferences [The Gear on the top right corner]

there you will find the RAM settings for MCreator, use the sliders to ajust the RAM

It already has 2 GB from what I can tell. Should it need any more?
