arri colour primaries and LUT

Hi All,

Couple colour pipe question. Im trying to set up a fusion colour workflow that works the same as our colour workflow in Nuke.

We have to deliver linear exr's with arri primaries so, in Nuke:

- read arri footage as raw (nuke automatiaclly converts to linear)

- using a colorspace node we convert the primaries to AlexaV3LogC of all comping assets such as srgb footage, stills and cg

- we comp through viewer LUT from a 3d LUT .cube file that we created with the LUT creator tool on the Alexia website.

Can we do any of this in fusion?
I cant work out how to:
- read a file as raw (I have a feeling that I may need to take it in to Resolve to do this)
- convert a files rgb primaries to AlexaV3LogC

Thanks for any help !!!
