What is this cave?

So I have seen this cave on about 3 maps but I cant get its vmf as the files are protected from decompiling, does anyone know how to get this cave or another good looking one? Or do I have to make my own one x(

“protected from decompiling” hmm, you are probably using VMEX which is old decompiler.

Download BSPSource (website is dead, get it from Valve wiki link) and you wont get any issue on map “protected” (invalid brush can always happen on map load ofc).
