Renderdoc

Renderdoc is a widely used open source GPU debugger. Blender has several options to benefit using renderdoc for debugging.

Frame capturing

When Blender is compiled with WITH_RENDERDOC=On you can start and stop a renderdoc frame capture from within Blenders' source code.

1. Add GPU_debug_capture_begin/GPU_debug_capture_end around the code you want to capture.
2. Start renderdoc and launch from within renderdoc using the --debug-gpu-renderdoc command line parameter
3. Every time the GPU_debug_capture_begin/end pair is reached it will automatically record a frame capture.

Command grouping

With the command line parameter --debug-gpu blender will add meta-data to the buffers and commands. This makes it easier to navigate complex frame captures. Command grouping is automatically enabled when running with the --debug-gpu-renderdoc option
