RenderDoc

RenderDoc is a very powerful tool which can help us find problems with our code/engine/idea, it's a frame debugger.

Most of the time when people start out, first thing which isn't working is the first triangle or the 2nd triangle right after that.

They tend to get a black screen and then don't know what to do next or how to fix it.

That's where RenderDoc can help.

You should get it right away from here and install it.

It comes with a useful Getting Started guide which you SHOULD read.

Please read it, it takes only a few minutes but explains the basics of how RenderDoc is used.
