Forge/Optifine Installation Issue

[KaedenCraft]

Got Forge running beautifully, got each Forge installation tucked into its own subfolder to keep the mods lists separate. But now, I want to install Optifine. Every tutorial only installs Optifine by dropping it into the .minecraft/mods folder, but I'm using custom installation folders not inside .minecraft, and doing the same thing (dropping Optifine into the /mods folder) doesn't work, it crashes with a Renderer error on startup. Is there a solution to this? I can't seem to find any guidance at all through Google or YouTube. Thank you.

Post logs, chances are you are probably using a version of optifine not compatible with forge. Check the optifine changelog for the version you are using, the last entry in the changelog for that version will tell you what, if any, version of forge it works with.

See? First time this has come up  Let me check that.
