Hey guys, I have a custom script working for exporting tiff files. All the logic works and Im using a custom preset for converting my custom maps. The issue Im hitting right now is that it always exports every texture in the preset, regardless if it has information in it or not. So now Im trying to find a way to only export textures that have "Is Computed" set to on. I know I can update the script everytime I have a different set of textures that need to be exported but that seems silly.
I've looked through the API documention for sampler and nothing stands out that appears to answer this goal. Also I have also tried to make calls to the export api that is standard in sampler export process. The idea here is maybe I can set the active channels in that list and use that as a way of exporting what I need. I was blocked in this attempt too.
Curious what you guys think and if there is a way to only export "Is Computed" channel that are on.
