Issues working with very high res files.

[ripe]

Would appreciate some help when rendering large (15000x15000 pixel) images please?

My normal workflow is render as a Vrimg file so I get all the render passes in one file - then open in Photoshop as I have the Open EXR plugin installed. BUT recently i'm getting a 'not enough RAM' error in latest Photoshop and the files won't open even though in task manage i'm only using 25% of my 128GB ram

Any tips for a decent workflow to open large files rendered in Vray in Photoshop?

I simple save as TIF. / 16bit maybe preferably. and load in PSD as " load Stack" . Or just via "copy and paste" desired Layers from FB into Photoshop. That's works like a charm.

You probably did this but...check scratch disk size and RAM allocation...you never know

Appreciate the reply caypiranha Will give that a go.

thanks fixeightted - already checked all that - I have a dedicated SSD as a scratch disk too - tried opening the files on my new Threadripper PC with 128MB Ram and task manager is reporting that Photoshop is using around 25% Ram allocation before it gives me the error - so seems really odd as there must be loads of headroom so something odd is gong on. On my Mac - the same files won't open - same error.

Ok, another thought...have you tried saving as e.g. exr with all the layers...just to rule out vrimg issues out?

Will try that too fixeighted
Also - thanks so much caypiranha - the save as 16bit Tiff stack and bring into PSD worked fine and i'm able to work with my renders again

In 16 bit integer, however, not floating point.
You're missing a good amount of precision this way, in the math operations.
Just something to be wary of.
