Hi there
I'm not yet sure about the cause of this behavior (I'll write when I find out), but sometimes the EXRs I save from PV are clipped to the luminance of 0,99. I always follow the same procedure:
1) Stop the rendering
2) Denoise
3) Send to PV
4) Save as OpenEXR
5) Post in ArionFX
Corona tone mapping, LUT, bloom/glare and sharpening/blurring are all off.
Clipping happens randomly even in scenes previously rendered without any problems. Recently, a client requested me to re-render a scene in a bigger resolution. It rendered fine a couple of days back in the same version of Corona (2017-06-27), but two of four new images got clipped to 0,99. Thankfully all EXRs saved from VFB are ok, but in general I prefer saving from PV as it gives a nice, single-layer output without any alpha-related issues. So, if anybody could kindly share a tip for fixing this random clipping, I'd greatly appreciate it:)
Note: Clipping occurs also in version 2017-07-11.
Cheers
