probs with an older project from last year...

[Komposer]

Hi,

I´ve a bigger project from last year, an offshore ship scene.
Now I´ve to work forward with the scene.
But somthing is wrong now.
The renderprocess starts, cpu usage is 100%.
But the render progress stays by 0% - for hours when I dont stop it.

I installed vray 2.2 a few days before. (maya 2011, win7)

I made many tests today, reducing the things with help by renderlayers!
And it helps, because the render progress go forward - but totaly slow - unbelievable!

I made a test with maya 2012 - the same.
I installed an older vray version from august last year - the same prob!!!

I´ve no idea what happens here.
I hope on help or good ideas.
I read that there must be a debug log - but I dont know where I can find it.

Other older, not so big projects runs perfect!

Thanks for help,
Jörg

On Windows, the V-Ray log is the temporary folder for the current user (type %temp% in Windows Explorer) and is called vray4maya_log.txt; is there things like proxies, displacement, tiled OpenEXR textures in the scene? If yes, what is your dynamic memory limit set to?

Best regards,

Vlado, thanks for response.

Now I found the log file, but I mean that there is nothing special see.

I´ve one disp with vray watertex, the dynMem was 2000.

But now I Imported all objects and cameras, into a new clean file.
Set dynMem to 5000 (I´ve 8GB RAM).

Many of my objects was smoothed per maya option.
This was clearly one of the probs - minimum 10 times slower than subdiv option from Vray!
I´ve no idea why - never saw such dramaticaly diff between the both options!
But I love the subdiv option, so its fine for me.

Could it be, that the new Vray version renders with the same settings in higher quality than before? (and need more time)
I mean, that I could clearly lower GI settings, shadow samples and a bit AA, with same HQ result.


So, now I mean that my renderspeed is normal as before.

Cheers,
Jörg

There was a particular issue where the older version didn't sample dark parts of the image very well and needed very high settings to produce a clean result. This is fixed for newer versions and lower settings can be used for the same result.
