Hi, I still have the problem and the cause clearly is not the memmory of the HDD, I have enough memmory now.
I don't know what is happening, it doesn't save any of the elements. This last render I chose only vrayrawglobalilluminationmap and vrayrawlighting and it didn't save them to file.
It's very strange because it renders perfectly in the window.
But curiously if i try at less resolution than 2048 it works..
Does anyone know what can I do? I'm desperate I can not do tests of 9hs for nothing..
Also, is there any way to recover the elements from the render window with any option and save them manually after the render is done? With the VFB I could, but I can't use it because I'm baking..
