first off the bat everything being in a new age SDK menu i like. all the tools are in one place so importing custom assets is a breeze (thank you for your service VTFedit). as for hammer editor itself this will take some serious getting used to. some of old hammer is there but a lot of things keep catching me out like holding shift instead of ctrl to select multiple objects. things like texture alignment and entity properties are nothing like what it was. i am still getting used to it but muscle memory has me used to the old shortcut keys where i could quickly and efficiently make things but now simple actions are very slow and clunky because of the change. i spent like 10 whole minutes trying to select a brush i accidentally made to delete it which involved me having to move the brush it was inside to select and delete it. old hammer would just let me clip inside the existing brush to select the one i want to delete. i do appreciate how they cut out the fat in some places like light environment automatically adjusting itself for the skybox, but i was so used to doing that manually and it was no big deal. in some places the fat cutting doesnt even work, like the 3D camera being used with any tool selected. when im looking around i randomly select things and move them when all i want to do is move the camera.
all in all i think they fixed everything. including what was not broken. and before people say “HEY TIMES A CHANGIN THINGS GOTTA BE DIFFERENT” they couldve kept the interface identical and achieved the same goal by adding on to it.
