In other words Vray will be rendering at 4000 pixels wide to determine IR detail, when it has probably seen enough at 1000 pixels wide (or even less). Since you have a Max rate of +1, you will be getting a precalc of double your output resolution. A max rate value of -1 will be half the final output, and -2 half that again. A Max rate of 0 means that that maximum precalc resolution Vray will use to analyse scene detail for IR samples will be the same as the render output resolution. These settings are very high for an exterior render.įor example - The IR. I can empathise with your getting to grips with the numerous Vray settings, however a bit more reading and understanding about what these settings are doing will certainly help you in the future. I needed this on A2 size paper, so my output is 2048 x 1536.Īre my settings above ok to produce quality image also? What could be the cause? Should i remove 'materials' on these background items?Īdaptive DMC, min subdvs 1, max subdvs 6, noise threshold 0.005Īdaptive amt 0.85, min samples 8, noise threshold 0.005, subdvs mul 2 I have hid many background items, and exploded all of them.
So i would really need some insights from professional. But i am too novice to detect the problem in my own settings. I have read read many threads on 'how to speed up rendering'. But when i put in my background buildings/ roads, it gets super slow that it is still 'building light cache' when i came to check on it.
It is ok when i render my building alone. My simple Night Render is unable to render within 7 hours in the settings i used.
