They are prop_static, but i have also tried prop_dynamic, and that doesn't Work either.Are they prop_detail or prop_static?
You say you get "errors". Do you mean the substitution model or in the developer console?
Either way, how are you packaging the custom content?
I know! That's also what i did!"models or Materials" is not a folder. You have to, quite literally, place it in either "models" or "materials". Model files go in models and material+texture files go in materials.
Wow. I moved tf2 recently, and i forgot to move the hamme directions with it. Thanks for helping!Are you running Hammer and/or TF2 from a non-default location? It's possible Hammer is looking in the wrong place for custom content. Go to Hammer's Options menu (Tools > Options...) and make sure Hammer is configured to look in the right directories.
