Vray 3.40.03
Max 2017 SP2
Hello !
BIGPROBLEM i have
When i prepare my renderscene for rendering animation, Irradiance file and light cache file are not saved even if they are checked to be saved !!!
The files are created… but they are empty
You need to render the scene and then Save the calculated lightcache files. Otherwise they will be saved but will be empty like in your case.
Uh ?
But it’s mean that it have been modified since the vray 2.5 version ?
With 2.5 when we rendered an animation you needed to render first the light cache and after the irradiance each time with the “don’t render final image” checked !
So what you explain, is : i need to save the image of the rendering (PNG, JPG or whatever) for a correct saving of the IRR and LC files ?
I think i found the solution…
Reason of the problems : The options “Autosave” was not activated in expert mode… WTF !!!
Actually nothing has changed since 2.5 in that direction, Auto save option was always disabled by default. Also maybe you misunderstood me, I haven’t said anything about RGB saving. What I meant was that if you save the Light cache before rendering it will create 1KB empty file, like in your case. So if you want to properly save the LC file you need to either use the Auto save option or manually save the file after its been calculated.
No problem Zdravko thanks for your answer.
I checked the autosave, and it works very well !
What happen with the new menu of vray (For me it was a big change 2.4 → 3.4 lol and very good performances !) : is that i didn’t noticed that if you choose in irradiance parameters for example, the light cache stay in .
It seems that the reset button doesn’t work.
Thanks svetlozar.draganov for the tricks regarding to the right click !
