Hotspots (Fireflies) in saved file but VFB image is fine!

[kingsimaging]

(VRay Next update 1.1) (3ds Max 2018)

 

I made a simple scene lit with a domelight (HDR IBL) and did a render to texture (VrayRawTotalLighting). The render output displayed is smooth and properly lit but the file saved to disk has fireflies (high intensity noise).

 

I can save the file from the VFB and it saves just fine. But I have about 60 lightmaps to bake and I wouldn't want to manually render and save from VFB everytime.

 

Any suggestions would be greatly appreciated.

 

Noisy saved file

 

Clean image saved from VFB

Save format does not seem to have an effect...

 

 

Thank you
