I was trying to load an EXR sequence and have a new node load a color transform each time.  
Sounds like there may be a python script that does this?  
` *> 2 - Convert from Linear to Arri LogC (AlexaV3LogC)`\*  
_\> If you toggle the session manager, you can go to the big plus button, and add a `New node by type -> LinearToAlexaLogC` . This a GLSL node that will apply standard computation to transform your images from linear to LogC. **You can also add this node through a Python script so that it’s automatically added every time.** _

RV support said to ask the Forums for help with this as they are too busy to help? Is this something that any is comfortable walking me through? Or sending my the python script for?  
Thanks in advanced.

For anyone else who stumbles across this post, I’ve added an example package on how to enable `Linear -> LogC` conversion for EXR files here:

> AlexaLogC in Linearize Pipeline - RV Developer Example Series In this example, we provide a simple package to automatically enable AlexaLogC in linearize pipeline for EXR images. RV has a GLSL node that will apply standard computation to transform your images from linear to LogC. You can do this manually by toggling the session manager, going to the big plus button, and adding a New node by type -\> LinearToAlexaLogC .\* About this series: Over the years, I’ve made a number of packages for mysel…
