Long building acc. structure

[hrvojezg00]

Since upgrading to 1.5, I have very long "Building acc. structure" issue, sometimes more then 2-3 min for a regular 20m poly project (no proxies). What could be causing that?

What could be causing that?

because you don't use Corona 1.6 ;]

[hrvojezg00]

It`s not official so I`d rather not use it in commercial projects, too risky.

turn off displacement.
assign an simple Corona material as override mat.

and debug your scene ...

Does 1.6 db fix this issue? Ondra?

Is the slow loading of "acc structure" happening in any scene, or only in some specific, complex scenes? Are you getting any error messages? Is this happening in DR or in offline rendering? The more details the better.

Hi Maru,

It happens in all our scenes lately, no error messages, no DR. Cpu`s are at 100% at that state but nothing happens for a few minutes.

Can we get a problematic scene from you to debug it?

[hrvojezg00]

Ondra, it was some W7 issue, all worked out weel after Windows update.
