HLA’s hammer work just fine if you don’t have vr, SteamVR require an external tool to work correctly on pc, this: GitHub - Plaonder/SteamVRWorkshop-NonVR: Starting SteamVR Workshop Tools without VR enabled
Also if i’m correct, HLA’s hammer is the most up to date
But really it shouldn’t affect your work too much, what you really get if you use HLA instead of SteamVR is more assets since you can use HLA’s assets, but in another way you will have to port them to S&Box once you get your hands on it.
And there’s still the workshop for both, HLA and SteamVR.
In conclusion, HLA just give you more elements to work with quicker, but at a price. At the end of the day, if you are looking to learn mapping correctly from A to Z, then starting with SteamVR will definitly not put you back, you’ll just have to find textures and props on the internet.
Just avoid dota2 hammer tho.
