Trying to pull a depth pass into after effects

I am pretty sure I have it set up to render in Houdini but ae doesn't seem to like it.
I have tried .tif, exr, 32 float, 16 float\integer, etc.
what the heck. I have Houdini set to render them as ‘Different file’ so it is only one layer.

I have included a shot of my render settings.

I was able to get this sorted out using the ProEXR plugins
the problem was me fumbling on how to properly use them

took me a while to find this, maybe someone else will find it useful
