Animation sequence Render Layers + OpenExr i am trying to render multiple renderPasses, which i know how to do
In a sequence, which i know how to do, 
using MultilayerOpenEXR which i know how to use.

But togetger it just aint working.

What happens is only one Renderlayer+passes exports to the EXR, others has folders and layers, but are black(or white).

In Compositor, the renderpasses ARE contained in the render_layers node!

Any suggestions?
thanks

I am answering myself, the thing is that you have to

- untick "OVERWRITE"

All your renderlayers and all passes will be stored in a single EXR file per frame.

superuseful!
