PC Abe's Exoddus Demo Beta Area with replaced working CAMs

Decided to create thread of this to here.
So i have been trying to replace screens in demo Abe's Exoddus Beta area.

There is just little change to video: I said in video that i could not replace the screens with rock sacks. But this is now false! After Paul's hint i found out how to add any resource to any CAM (Screen).

So for first i try replace beta area with full version screens temporarely and then maybe afterwards put the beta screens or some of them.
