Hi Maru.
Indeed, some paths were set up wrong.
Don't know if this come from Max or Corona, but when I set up my output path, in the common tab (render output), the path set up for each render element gets wrong.
1- By just deleting these output paths, I can render in .cexr.
2- While I'm writting this, I've just seen that when the render stops, Max tells me it can't write the output file...
Please note that I have this issue just with .cexr, and this is working perfectly with all the other formats. Also, the path exists and is properly set up.
What would you suggest ?
I'm using Max 2016 + Corona 1.5 (hotfix 1)
Thx !
EDIT:
for example when I choose .cexr, my output path is this one
renderoutput\Shot_001\Shot_001_Light_Top.cex instead of .cexr ?
but in .exr it gets like this
renderoutput\Shot_001\Shot_001_Light_Top.exr
