/** If _IRR_D3D_NO_SHADER_DEBUGGING is undefined in IrrCompileConfig.h,

it is possible to debug all D3D9 shaders in VisualStudio. All shaders
|
||||
(which have been generated in memory or read from archives for example) will be emitted
|
||||
into a temporary file at runtime for this purpose. To debug your shaders, choose
|
||||
Debug->Direct3D->StartWithDirect3DDebugging in Visual Studio, and for every shader a
|
||||
file named 'irr_dbg_shader_%%.vsh' or 'irr_dbg_shader_%%.psh' will be created. Drag'n'drop
|
||||
the file you want to debug into visual studio. That's it. You can now set breakpoints and
|
||||
watch registers, variables etc. This works with ASM, HLSL, and both with pixel and vertex shaders.
|
||||
Note that the engine will run in D3D REF for this, which is a lot slower than HAL. */
