Is there a way to avoid the seemingly unnecessary cost of UpdateDepthTexture?

Unity Engine

Looking at the Frame Debugger in Unity 5 I see that everything is being draw twice. I’m using forward rendering and have some large geometry that I would really prefer not to draw twice. Is there a way to avoid having this geo go through UpdateDepthTexture? If not, can this please be fixed?

Image Effects will often require it though.

I would prefer to have some choice over that especially when targeting mobile.

In case anyone else runs into this and is looking for a solution it looks like a potential workaround is using command buffers for finer control over the rendering pipeline. I’m experimenting with a command buffer to render my mesh after the UpdateDepthTexture pass which seems to work. Not very convenient but it’s better than nothing.

It’s crazy to think that Unity is still rendering things twice, is it still doing that in deferred mode? Because that would be very odd, especially on Windows & OSX.
