Whenever I open minecraft and go to one of my worlds it will say building terrain and then crash. I dont know what the problem is. I'm using several mods including shaders and lagless shaders. Also whenever i install a new mod I have to make a new world so I get a new spawn point and have to start over, so its kind of annoying. And one more thing the loading world takes SUPER LONG. Sorry about all the problems with my minecraft. Any help will be appreciated.

This is the crash report by the way
