Cryengine3 debugging shader method

CryEngine3 have access to GPA  RenderDoc  NSight Wait for the tools to go ahead Shader debugging , The premise is to open CryEngine Of Shader The specific method of debugging mode is as follows ：

1. Turn on Shader Edit mode ：

    stay System.cfg or Editor.cfg Add the following variable parameters ：

sys_PakPriority = 0
r_reloadshaders = 1 
r_ShadersEditing = 1

  here , Can be loaded Shader Source code , Instead of loading shadercache.pak, Loading the source code also requires Shader.pak Extract to the same level directory .【ref】

 

2. Delete cache directory

  Delete shader Cache directory in CryEngine3 and shaders The original catalogue is in one piece ,CryEngineV Then default to ：C:\Users\Administrator\Saved Games\gamezero\shaders\cache

3. To configure shader Build server ：【ref】

r_ShadersRemoteCompiler=1
r_ShaderCompilerServer=127.0.0.1
r_ShaderCompilerPort=61453

4. Set up shader Debug mode ：

r_ShadersDebug = 3

r_ShadersDebug
DUMPTODISK
Enable special logging when shaders become compiled
Usage: r_ShadersDebug [0/1/2/3]
 1 = assembly into directory Main/{Game}/shaders/cache/d3d9
 2 = compiler input into directory Main/{Game}/testcg
 3 = compiler input with debug information (useful for PIX etc./{Game}/testcg_1pass
Default is 0 (off)
