Placing Props in a Level
From RoboBlitz Editor Wiki
This is really easy. It's basically the same as in unreal 2kxx. Just there are a lot more items in the menu and you really have to look what your options are.
1. Get the Generic browser open by going view generic browser and scroll down the upper left side menu till you see the Static Mesh package. Click the package to select it and then go to the pane that is right under where you clicked the static mesh. This is where the meshes are located at, next you need to pick a package to select and I choose the MISC_PostDefaultload and then picked the Blitz_ball.
2. Minimize the window so that you are back in the editor. Now right click in the perspective view and go to add actor and there it will be at the top of the list and it will say static meshes by the name. By the way this list will also store your last choices for actors and lights that you pick, just a heads up. Once you do this you will see it placed in the level, I had to pull mine up.
3. Now play the level and that’s it. Hope it helps
!!!!!!DONT FORGET TO SAVE!!!!!!!
Making Props That Can Move
To make an object that Blitz can pick up, or move around place the static mesh as an RDestructible. To do this right click in a viewport and select Add Actor->Add RDestructible: Static Mesh MISC_PostDefaultLoad.Blitz_ball. If you just want something that can be moved around without being picked up, you can add it as a RigidBody instead.
