Reload various EXR's

[LewisJT]

Hi guys.

Would anyone know if its possible to re-load, various, previously saved EXR files. One at a time, so as to resume render and update designs via region renders?

Aiming to quickly cycle through design iterations of a retail interior through several camera shots for a client at 4K.

Any help, ideas and guideance would be greatly recieved.

Simply load them in the VFB (VFB>File>Load) and render regions on top?

I think what Lewis is trying to say, that at render start, the VFB loads a previous EXR so it renders on top of it. This is actually not a bad idea. Could this be implemented?

Vizioen Is automation the only difference from what I suggested or am I misunderstanding something? A simple script can do that (load, set region and render) for you:

vfbcontrol #loadimage "C:\Users\Alexander\Desktop\image.exr"
vfbControl #setregion 0 0 640 480
render()

[Vizioen]

Yeah sorry I was not really thinking straight, this should be indeed automated otherwise it's quite useless.

Great responces guys, and has certinly answered my quiery.

However i do have another question very closly related.

Imagine a scernaro...

• Interior scene
• 20-30 cameras
• Each camera set up within batch.
• Client changes a product within the scene
• Each camera requires its own specific region render to replace the product

Q: Can a region render be set specific to each camera?

Q: Could the batch run updating each camera shot by...

• Loading the previous image
• Rendering the specified region over the top
• Saving the new image via overwrite
• Or as an additional ie 1.1

If protocall is to begin a new topic, i'll happily oblige

Q: Can a region render be set specific to each camera?

Not directly. A script that detects a specific camera and sets the region according to it should work though. This may be a bit complicated to write since the region will differ for each camera.

Q: Could the batch run updating each camera shot by...

This may also be included in the script. When rendering Batch, the script can be trigger after each render (Render Setup>Common>Scripts>Post-Render).
