I find the problem that I have to compiler Vulkan with Mali Offline Compiler at where malisc.exe is installed, otherwise will prompt "ERROR: external\glslangValidator.exe does not exist."
I also met with same problem when I use offline shader compilers in Material Editor Of Unreal Engine4.
Is there any plan to fix the problem?
Thanks for the bug report. Will raise with the engineering team to see if we can get this one fixed.
