UHD cache - animation preset strange black render result ??

[atelieryork]

And what if i have my scene (so made in 1.2.1) , and i upgrade to 1.3 by myself. By upgrading, does it change anything in the render result?
Should i change something ( like when i upgraded to 1.2.1 and opened an old file,  i had problems with the old version sun, so i had to change it ... )  ?
'cause if not, i am up to upgrade of course  (even rebusfarm, i checked they support now! ) :)
Thanks!

It should look the same or very similar, BUT you won't easily be able to re-open the saved 1.3 max files in 1.2.1 if you decide to roll back for some reason, due to several material values changing. So, basically, once you upgrade and save the max files in 1.3 you will need to stay in 1.3.

I See, but i think i give a try, upgrades are always better!
Thank you very much!

Remember to backup your scene if you wish to get back to it for some reason.

probably resolved with the displacement NaN fixes

Same problem here. I have small scene with no displacement etc. all in corona custom material and nearly 20 % of the frames were black.
When i red this topic i've changed to PT + PT and everything seems fine.... just render will take sooo long time... i have 1200 frames.

what Corona version do you use? can you share the scene?

If I am correct, you are running out of Ram memory. PT+PT will do the job but slower.
