File extremely slow to load with IES

[3LP]

Hey there,

We are experiencing a huge problem with IES files currently.
We are opening files that where created before we updated to SP4 and it's terrible.
They contain between 500 and 2k ies lights and it just take more than 20 minutes to open, the cpu drop down at 2-4% activity.
We tried to uncheck everything beside the "enable" checkbox but it didn't help.
Even isolated, when the lights are not "enable", not "enable viewport shading" and not "show distribution", with 2k lights the viewport drop down at 0.5 fps.

Any ideas?

Hello Stan,

Would it be possible to attach this file - if you are sure that IES light cause the issue you can remove everything else and leave only the lights.
Does this issue persist in the earlier Vray versions ?
Let us know the exact Vray and Max versions you are using.

Thank you very much in advance.

Sure,

Is it possible to send it through email or any file sharing site or ftp?

Thanks

Stan

Hi Stan,

You can send an email to vray@chaosgroup.com with all the information and link (the most convenient way for you) to the scene file.
Note that we can provide you with our FTP server if it's needed.
