Yes! Cairyn you are right! That's what i want to do. I want to remember the state of the object at a current render.

@cairyn said in Log in annotation tag (python):

Why don't you just put ALL the CURRENT data for these objects into the tag? So the annotation would say "the camera is x; the color of the flower is blue; the background is mybgr.hdri". No comparison, just the current data that you are using for this render.

@m_magalhaes i want to write it by myself.

@Cairyn offer next way "My best approach would be to store the last scene state somewhere and then do a full comparison of all objects with the current state of the scene, including all parameters of interest."

To my mind it's a great variant.
But i haven't got any idea how to do it. I don't want to make a log for all changes it will be enough if i could do it for important parameteres of object.

"...and where would you get those changes from?" That why i asked about it. Why is it mostly hardcore ideas that come to my mind...

Cairyn, thanks a lot for your answer!

Hello for everyone! Anybody know how to send changes of project in annotation tag?

What i mean when i talk about "changes". For example, you change position of light, color of material, position of object and so on.

As i understand i should convert changes in text and send it in tag, but i haven't got idea how to realise it.

The main idea of script:

1. Pressing on the render button
2. Null appears. It has the same name with render and it has an Annotation tag.
   The Annotation tag contains all changes in project.
3. If you press the render button after that you wil have new null with new changes

It's a kind of memorization of log...
