Its a bit involved on how to set this value on Plutonium as it is not controlled by a dvar, but instead uses Demonware.
First make a mods folder in %localappdata%/Plutonium/storage/t6
In that mods folder create a folder called zm_fix_graphic_content
In the folder called zm_fix_graphic_content create a ui folder, then inside that ui folder create a t6 folder.
Engine.SetProfileVar(0, "cg_blood", 1) Engine.SetProfileVar(0, "cg_mature", 1) CoD.Error = {} CoD.Error.Width = 400 CoD.Error.Height = 250 CoD.Error.SetMessage = function (ErrorPopup, ErrorMessage) ErrorPopup.messageLabel:setText(ErrorMessage) end LUI.createMenu.Error = function (LocalClientIndex) local ErrorPopup = CoD.Menu.NewSmallPopup("Error") ErrorPopup:addTitle(Engine.Localize("MENU_NOTICE_CAPS")) ErrorPopup.setMessage = CoD.Error.SetMessage ErrorPopup.okButton = CoD.ButtonPrompt.new("primary", Engine.Localize("MENU_OK_CAPS"), ErrorPopup, "button_prompt_back") ErrorPopup:addLeftButtonPrompt(ErrorPopup.okButton) ErrorPopup.messageLabel = LUI.UIText.new() ErrorPopup.messageLabel:setLeftRight(true, true, 0, 0) ErrorPopup.messageLabel:setTopBottom(true, false, CoD.Menu.TitleHeight + 10, CoD.Menu.TitleHeight + 10 + CoD.textSize.Condensed) ErrorPopup.messageLabel:setAlpha(CoD.textAlpha) ErrorPopup.messageLabel:setAlignment(LUI.Alignment.Left) ErrorPopup.messageLabel:setFont(CoD.fonts.Condensed) ErrorPopup:addElement(ErrorPopup.messageLabel) return ErrorPopup endNow create a file called error.lua in the t6 folder you created, and paste the above code into it.
Now launch the game, and click online in the mainmenu, there you should see the mods button, click it and load the zm_fix_graphic_content mod.
Loading the mod should have reenabled graphic content even when you unload the mod.
