what is a sv_setbrushmodel : null?

Means you have a phantom brush. Open up the entity inspector and see if you have a func_door or something with no brushes attached. This can be indicated if your entity has no plus symbol next to it. Just select the entity and hit backspace to delete it. You should be able to recompile and play the map.

wow i had 3 unused door entities thanks ill post my map as soon as i can.

sometimes, the only way i can fix this problem is to select the whole map, then copy, and paste it into a new map.  just if no other way works, though.

i have gotten the error a lot now (its pring break so all i do is map) and i go to view entity list and delete all the ones without a triagle nest to them

SV_SetBrushModel: Null is a brush error e.g. trigger_hurt with lava texture or mirror on doors.
How to repair?

Select all the map, copy and paste it to new map, save and done. It must work.

Look at the origin. Are there "phantom entities" there?
Press L and select these entities. Delete them then recompile.

These "phantom entities" appear when a previous entity member is turned into a new entity. For example, I create a brush, select it then make it into a func_door.
I then decide that the door needs more detail. I create some more brushes, select them and the original door brush then make them into another func_door.
The original func_door is now empty and in Radiant 1.5 appears at the origin. It can only be selected from the entity list. This is why the select all and copy method works.

The kicker is that it happens at random. I can do exactly as Taiyo.uk just posted and only sometimes will it happen.

[lizards160]

it shouldn't be random

You could have done a search on the forums. There is the answer thousands of times in different topics.
