Just experienced a big problem when we switched over from 9.0 to 9.1 today. Unfortunately we didn't catch this sooner.
Seeing a massive difference between these drops output from 9.0 and 9.1.98 - you can see the difference in the realtime as well - but not as extreme as the outputed images.
Everything is the same - only difference is 9.1.98 instead of 9.0
Windows 10 - CPU rendering
** We see the drops not turn black when caustics are on..but we've been able to get by without caustics until now, and we'd like to keep it that way - caustics taking so much longer to render for not much gain in our specific case**
Thanks
