hi im triying to render my scene in high quality o vray expresss setting, i calculate first and dont render final image, make calculation with a 320x200 Window, then store LC and IM and rerender final image at 1440x900, he starts the distributed render, and let him work, torn of monitor for night rendering, but ooooooo surprise whrn i turn on the monitor, he has restarted. don’t know when, but at least like som point after half rendering process.
The biggest thing that causes “random disappearance of slaves” are windows updates that automatically restart the computer. I’ve had this happen to me several times and its frustrating. Its highly unlikely that a spawner would cause your whole system to restart. It could crash itself, but that’s about it.
Another note, you should precalculate your IR solution at something close to 800x600 then reuse it. Precalculating at 320x200 is far too low of a resolution and unless you’re using what would be considered overkill IR setting (ie a max rate of 1 or more) then you’re probably getting a lower quality solution that you would at a standard screen resolution.
so for example for a final render of 1440x900 I should pre calculate light at a lower resolution but with the same aspect ratio ( eg. 1440x900 = 1.6 apratio = 800x500)?
How can the render process for a high quality render should be? ( a list wold be nice, noting complicated)
the thing is that my english is not that good to understand the workflow tutorial…i have a lot of problems setting a exterior render setting and getting high quality in some billboard bitmaps they get pixelated when saving them as a JPG.
look here to see what im talking about…
For the crashing thing, Windows installation updates aren’t activated in my computer, but may be it coul be, i remeber a geniune software installation before I started to render…and it minimized to the tray, then y render my scene and went to sleep…jejejej so probably it could be and not.!
jajajajajajajYou were right, the “save file” option in the output panel, saved not only my render automatically, but my a** too, i browse my folder, and yes, there it was my saved render. if i want consecutive renders names y should check the raw image option?
Yea you want to make sure that the aspect ratio is preserved. Precalculating IR maps for high res is the main component and that alone can take hours and hours off of calc time. As to your JPEG issues, I’d advise that you don’t save to jpegs since there’s no control over the compression. My daily format is pngs, my medium quality format is tga, and my high quality format is either HDR or EXR.
i savedsome renders in BMP and preserved well the quality better than the JPG compression, so I wolud try the ones you recomended me, the renders have simple post-process in photoshop, so what i really need is a mid-quality and the BMP worked well for now.
The alpha channel is just generated by geometry. If you don’t want the PNG to save with the alpha channel, the remove it and pngs will without an alpha channel
