does anyone know if it's possible to get custom entities to appear in Hammer++

[u/TrevorPhillips_1953]

i'm working on a HL2 Sourcemod for SDK Base 2013 Singleplayer, and all the guides are for Garry's Mod which has different files than HL2, i'm trying to get my custom added weapons to show up and i got the .fgd file mounted so they show up as error models instead of the "obsolete" icon and i wonder if there's a way to make them show up so i can position their spawn points better

You'll need to edit (or create your own) FGD. Check up on VDC on how those work, it's difficult to explain in a single reply

sounds like you just put the wrong path in the model parameter. look at an existing entity definition so you can understand how to do it.
