I have an idea for 2 new static objects that can be used in pipes.
The first object has the shape of a half-circle or a really flat half-cylinder. You can put it into a pipe so one half of the pipe is free and the other half is blocked. The editor of course allows you to rotate it how you like. :-)
The second object has the shape of a bar. Similar to the existing concrete bar, but flat so you could place it in the middle of a pipe. Useful to block only a small part of the pipe.
The object materials could be concrete, plastic/glass-like (similar to pipe material), etc.
Other ideas for pipe-blockers are appreciated.
PS: I don’t know jack how to create objects. xD
