Hey all!

Whenever I try to use Hammer after 1 minute or so after the maps been loaded, Hammer crashes.

It's really pissing me off because I can't find a single reason why it would be happening.

List of things I tried already:

• Decreasing back clipping and model distance
• Updating video drivers
• Turning off my antivirus

Please, if anyone can help with this please let me know!

Always try to verify your local files first, for both the tools and the game:

• Go to your steam Library (All Games) > Portal2 > Right click > Properties > Local Files > Verify cache of local files

(wait until it finishes)

• Go to your steam Library (All Tools) > P2 authoring tools > Right click > Properties > Local Files > Verify cache of local files

Does it crash only with 1 map? have you tried loading a different one?

Oh, I forgot to mention.

I tried that too.

It's crashes with all maps.

Hammer just does this sometimes. As far as I can tell it has a big memory leak, so you effectively have a certain amount of time from when you start it up before it dies. The texture browser and model viewer make it worse, try not to use them.

ou can use the old model browser (Which is like loading a model into hlmv), But, there is no getting around the texture browser from what I remember.

I noticed that increasing RAM makes hammer much more stable, but yes, hammer will crash.

I still don't think you understand what is actually happening.

Hammer shouldn't crash with no programs open and a empty map.

I have at least 8GB avaliable so it can't be a lack of ram.

It fixed itself.

I assume it to do with deleting the src maps folder.

I just had to cycle through each map to confirm to Hammer that they are deleted.

ah alright! good to see it's fixed
and yeah; 8gb RAM should be more than sufficient

your trick might help others some other time though! thanks
