brush
Its will be possible to make brush or something solid blockade for fixing bugs on custom maps via gsc scripting
Brush must exist on both server and client to prevent desync (small flickering when you stand on top of it - client thinks there's nothing here when server blocks movement). So it requires massive client patch including server-to-client brush position update (like using configstrings).
Right now you can use cloneBrushmodelToScriptmodel script function with bombsite entity - the most known script_brushmodel which exist on most of custom maps.

i know about spawn trigger_radius that works to be solid by setcontents(1) but its circle :( i need block with custom dimensions :(
Sorry, but adding a collideable brush will require massive hooks to internal map storage (where lumps are located) from both server and client. I guess, only guys from aIWNet team knows how to achieve that.
