    Hi Kate, thanks for this.

    I usually import my .exr files into Resolve in order to add audio and for slight color adjustments.

    Since first doing that with resolved I noticed a whole section of different LUTs that could be applied, intrigued I never researched that to understand what it's all about.

    So with your tut here I was interested in returning to the subject.

    I noticed the file extension is .blut

    I'm guessing this is a type of lut format meant only for use in Houdini.

    Or is it? What do you know of the needing or not of having to convert Houdini .blut files to other formats for use in other software, and vice versa?

    Hi there! Thanks for asking. The .blut file format is a Houdini LUT format that supports binary encoding.
    You can read more about them here:

    I used a JPEG file type in this tutorial, as it was the quickest file I had available on my desktop, and I thought it might be fun to try and work with a file type that automatically has the color space baked into it. As well as what challenges would appear while doing that. You are right however, as EXRs are probably the most easiest type of file type to work with while compositing.
