Hello,
I suppose you are rendering with IRay. What I do is increase the maximum cycles and time for the render in this case.
Greetings
P.
yes i a using iray
As Philopp said, most likely you want to increase the render time and/or the number of maximum iterations in the render settings (under "Progressive Render Settings". It also helps to increase the render quality and the convergence.
Did your render finish because it had reached the two hours standard render time, or the number of iterations, or the convergence?
If you still have the render window open, you can change these values and continue from where the render ended.
it takes two hours to render?
never mind i see it i got it set to 5000 iterations i just uped it to 10k
No, the render settings have default limits, and when the first of that limits is reached, it stops the render progress. Otherwise, you'd render to infinity and beyond.
The "kill off" defaults 5000 iterations, 7200 seconds and 95% convergence at render quality 1. Any one of them is reached, the render stops.
then what can i do then to imprrove the quality change the direction of the light?
I do not understand what you are trying to say. Can you phrase it differently, or give an image example of the problem?
when im seeing the photo it looks grainy in the show like not fully smooth let me me render and show you guys
looks alittle grany around the window seal and soe on the body
There is no image?
i see it on the page let me attach one
heres the photo
Don't forget that after the render has stopped you still have the option to up the render time in settings and continue the render from where it left off.
how do you continue to render where it left off at
After it has finished you can go to render settings and increase the render time in Progressive Render, and then you should be able to resume the render.
Edit - and if it's only a small area that is grainy and the rest if fine, do a spot render of it and paste it onto the original image. Much quicker if a small area is holding up the completion of a large scene.
but do u click render again to resume the render or how do you do it
There should be a "Resume" button enabled once you change the render time.
thank you when i do a new render ill try that
There are two settings: Maximum cycle and Maximum time. The default maximum time is (if I recall correctly two hour). So probably you hit that limit. I set both up to the upper limit. And yes, I have had images that rendered more than 24 hours although I have a quite powerful workstation. Depending on the light sources and shaders you use it can take a lot of time.
