CXR File Save

[HTKsean]

The new Image Editor feature and the ability to save as EXR/CXR is awesome!
However, I was wondering if Corona requires that all Render Elements be saved as a separate CXR file? I have 4 lights in the scene + Environment + Interactive LightMix enabled, and when the render is complete, I end up with 6 files being saved.  The original output file(the one I named for output in the Corona Setup window) contains all the lighting info, so what's the point of saving out these other files? It's easy enough to delete them, but seems like saving all these files should be an option that I could turn off.

.cxr saves all elements into single file, so you dont need to worry about it - just one .cxr is enough

[ihabkal]

is there a plugin to allow photoshop to open CXR?

[Frood]

CXR is "just" EXR and uses EXR specifications to store additional information. So you can use for example ProEXR (free now) for CXR as for all other EXRs.


Good Luck

Hi all,

I hope I don't make a fool of myself but...how do I make 3ds to only save the .cxr file and not all the element in (EDIT:) SEPARATE ( .cxr  files as well? If I turn them off, they don't show in the master .cxr file and if I turn them on, they are in the master file but they are also separate which eats up hdd space for nothing. I'm pretty sure I am overlooking something.

Actually I'm asking if there is a way to save only one .cxr file. We only use one cxr file, but Corona insists on saving a cxr file for every lighting object in the scene. It takes time to go back and clean up the render folder by selecting and deleting the unused and unnecessary extra cxr files. Is there a way to prevent Corona from saving these extra files??

Just for clarification on the situation (others can confirm if this is what they experience)

- Save to CXR from the Save option in the VFB, creates only one CXR with all the layers contained in it.

- Saving to CXR using the automatic 3ds Max "Save file" option creates one CXR with everything in it, plus a collection of separate CXRs for each render element as well

the render element saving is handled by 3ds Max, we cannot influence it (well, we cannot without some serious side-effects) :/

This is correct, Tom. I was hoping there was a way to prevent the separate element CXR's from saving with each render, but apparently it is a 3dsMax issue.

Hi,
I have another question regarding CXR.

If I saved CXR through the VFB interface(Save CXR button), the file size is 1.4GB. However, if I saved CXR through Render Scene>Render Output>Save File, the file size is only 102mb.
It means the data is different.
When I'm using render farm, I have to save file through Render Output or Render Element, which means I can't get CXR with full info(such like tone mapping setting) to be used in imaged Editor. Is there a way to save full CXR if the image is rendered in render farm(backburner)?

Thanks!!!

Hi, it should be possible to save renders using the CXR format in Render Output setting. Saved results should be the same as using the Save CXR button. Are you using the .cxr file extension in Render Output?

Do you think is possible in the future to output in TIFF 16bit?
All the available formats for now are only in 8bit except of EXR and CXR (obviously).

Thanks,

You mean in CIE? Yes, it is planned.

Yes I was reffered to CIE, thanks for your answer...

Hi Mike,
you are totally right. I just did some further test. The CXR from render output is identical to the CXR from CXR button.
Thanks very much.
