Colourspace issues in Flame 2026/7

Hello,

I’m having issues getting consistent values for colourspace in a flame batch.

I have a project set up using ocio config 1.2 set in the OCIO variable. I have a PyWriteFileNode (which inherits from PyNode) linked to a read node. In the batch window the read node shows a colourspace of “acescg”. However, the new colour_space property doesn’t seem to work;

import flame
n = flame.batch.nodes[-2]
print(n.type, n.colour_space)
# 'Write File' None

If I use the workaround I implemented for <2026, I get the expected value;

import flame
from pathlib import Path
n = flame.batch.nodes[-2]
n.media_path_pattern = "<colour space>"
colour = Path(n.get_resolved_media_path(show_extension=False)).stem
print(colour)
# acescg

However, if I use a colour management node and transform the colourspace with ACES > ACES - ACEScc I get a different result;

print(colour)
# ACES_-_ACEScc

And then if I access the colourspace from metadata I get a different value again;

print(n.get_metadata()['autodeskColorSpace'])
# ACEScg

Which is not only in yet another format, but is now also incorrect, because in the previous step I set the colourspace to ACEScc, not ACEScg.

Metadata accuracy aside, these kinds of format changes make it really difiicult for pipeline to manage tooling.

I’m curious why you would not adopt aces 2.0 as a color policy since aces, aces cc and aces cg has not changed…

The colour_space property on Write File nodes seems to work for me. Are you sure it has something connected to its input? If so, perhaps you could work with support to help them reproduce the issue.

Regarding your ACEScc example, I’m not following what the issue is. You changed the colour space to ACEScc and that’s what is being reported, so it’s as expected right?

Regarding the “autodeskColorSpace” metadata, what you are doing there is getting the metadata that was in the header of the original file. It will be replaced if you write a new file, but it is not updated at every node through the Batch graph to track the colour_space property.
