Rendering with ver 1.3 is MUCH slower

[m.dallalonga]

Hello
i had a problem when i upgraded to version 1.3.
The issue consist in a major slow down of the rendering process e.g. the same scene (same camera/material/lights) now takes up to 8 hours when it only lasted few minutes with version 1.2.
I tried to downgrade back to the 1.2 version but it gives an error message stating something like "missing .dll".
I should also clarify that I'm using 3ds max 2016 on my 8 gb ram workstation.
Could somebody help me with this problem??
Thanks in advance for the suggestions!

This is propably due to embree being unable to start and thus disabling all accelerating structure.
Some time ago there was a problem with the installer being broken, might be unrelated doe.

Uninstall Corona, make sure all Corona related .dlls in your 3dsmax folder are gone

Code: [Select]

Corona_Release.dll
CoronaOpenExr2.dll
msvcp120.dll
msvcr120.dll
vccorlib120.dll
wxmsw30u_gl_vc_corona.dll
wxmsw30u_vc_corona.dll
and in your 3dsmax\stdplugs folder

Code: [Select]

Corona20XX.dlr
CoronaUtils20XX.dlt
Then reinstall, make sure the instraller gives the green light on embree.
And lastly, once you restarted max, look in the "development/experimental stuff" tab and make sure under "acc.structure" intel embree is selected.
