Ripping 3D Models using RenderDoc

[user3678]

RenderDoc is Graphics Debugging tool with a lot of shader debugging options, one of which is an option to view and dump numerous object's 3D Data as well as textures from GPU VRAM buffers.

Tutorial:

1. Download RenderDoc https://renderdoc.org/ [RenderDoc 1.26 - if you want to rip from Chrome too]

2. Download CSV to OBJ converter

 

0. Go to Tools -> Settings -> Allow process injection (restart required) <- Recommended

1. Click on "Launch Application", in "Executable Path" choose the game's executble and click "Launch" (The RenderDoc will hook into graphical API's before launching)

2. Press F12 at the moment when you look at the object you want to rip, minimize the window and now go to the RenderDoc again (Highest quality settings required for full resolution textures and max LOD possible at higher distances)

3. Go to "Pipeline State" -> "Mesh Viewer", or click on "Mesh Viewer", you will see there each selected mesh from "Event Browser" -> "Colour Pass #" -> "DrawIndexed" Drawcalls in two different forms: Input Vertex Shader (Original model) and Output Vertex Shader (Deformed model), right click on any of the columns in Input Vertex Shader, select "Export CSV"

4. Go to "Texture Viewer", click on "Open Texture List" icon, click on "Save selected Texture", click on three dots and choose the path and name, choose format, click "Save".
