Tips:

1) #pragma enable_d3d11_debug_symbols makes the shader code much more readable. Using it with a development building, would get me much more information like comments in the disassembled HLSL and the original code too.





2) apparently #pragma enable_d3d11_debug_symbols would work with d3d12 and pix too (not tried yet)

3) I am not using pix or VS as not only it worked in seconds with RenderDoc, but now render doc is even integrated in the editor: https://docs.unity3d.com/Manual/RenderDocIntegration.html

4) I strongly advise to try https://assetstore.unity.com/packages/tools/utilities/hdg-remote-debug-live-update-tool-61863 which can be very helpful either to profile and debug

5) 2019.1.0 : Shaders: Improve shader debugging by disabling the optimiser when generating debug shaders i.e. #pragma enable_d3d11_debug_symbols.
