You should be able to create a LUT from that generator that performs both operations. Have you tried these settings?

Load preset - Advanced

"Camera Data"

Gamma - Normalized sensor linear

Range - Extended

"Conversion Parameters"

Scaling - Photometric

"Image Destination"

Gamma - video

Range - legal

"LUT Parameters"

3D - Forced

Bits - 16

File Format - Nuke (makes a .cube file if I remember right which maya/VRay can use)

Hello all.

We are trying to adopt a more complete linear work flow in the 3D department of the vfx company that I work for.

The problem that we currently have is that 3D software ( in our case Maya rendering with Vray) renders out linear exr files. In order to use any of the LUT that are generated by the Arri LUT generator, (https://www.arri.com/camera/alexa/tools/lut_generator/) I need to apply a "pre" LUT to convert my linear renders into logc images that the arri LUT is expecting. Does anyone know how I can go about doing that?

Any advice greatfully recieved.

Kind regards,
Matt
