Cooking projects takes a long time in Unreal. This doesn’t have anything to do with Aximmetry. Make sure you’ve set only the levels that you’re using to be included in the cooking in the project settings. 

Hi 

thanks for your response but last week similar project or even bigger 

took only a few minutes 

now every thing is taking for ever

i don`t know what went wrong with unreal

It only takes a long time the first time you cook a project since it has to compile all the shaders. The second time you cook usually takes only minutes.
