Workflow

Next, you will need to set-up the HoudiniFX path to download the ACES configuration (most 3D graphics packages already contain a predefined configuration package), but in this case, we will use the downloaded version.

OCIO = C:\OCIO\aces_1.0.3\config.ocio

 

Start HoudiniFX and create a New project.
Next, create a ROP_sop, and create an Arnold_ROP inside it.

Arnold_ROP

Arnold_ROP-> Properties->Output

 

Properties->Device->Color Management

 

With the parameters called (IDT), you can change the color space by default for opening all images in your scene. LDR Color Space - this parameter set-up the default color space for an image with low dynamic range, 8-16 bit.
For example, choose Utility - sRGB - Texture for LDR Color Space. Now all of images color space (when opened in an Image node) are automatically changed to Utility - sRGB - Texture.

Next, you will need to change the View Transform (ODT) in the Render View and Mplay to Rec.709 (ACES).
