Alpha channel settings for EXR into After Effects

Recommended Posts

I'm having trouble deciphering the correct workflow for importing Houdinis EXRs into AE and then out for edit in Prem Pro (EXRs are exported from Houdini/Redshift with default settings).
It seems like the alpha channels are very weak, and leaving nearly my whole image transparent.  Does anyone have a tried and tested method which they could share for bringing Houdinis EXRs into and out of AE, for an export into a format like ProRes 444+alpha?
I've had a look at a few posts online and played around for hours with countless colour management and alpha premult settings within AE but feel like I'm banging my head against a wall.  
Ive attached the EXR and a Mplay vs Prem comparison.  
Thanks for any advice

i opened your EXR in Blender and these were the Alpha values on your file .

maybe you should tweak its values from the render

Yeh Mplay displays a similar alpha, but with all channels on it creates an image like in my post above, whereas AE/ Prem do not, the image has far less detail.  Maybe this could also be a Redshift thing..  I dont know yet.   By changing my AE settings to the following I can get the image to look similar, but whatever I export still seems to have the same alpha issue once in Premiere.  Perhaps this is starting to be more of an issue for an Adobe forum, but I just thought there would be some people here who have a simple answer, given this must be a very common workflow.    AE.thumb.JPG.0b108ccc8d248ccc28e04de855fff21e.JPG
