Hi all.. feeling great to join in a forum like this..... Me - kishore, i love 3d visualisation and i'm hugely inspired by the works of you guys...

Well I'm at pretty novice level as far as 3d visualisation is concerned .. I tried my hand at v ray .. and this is my first render.. saw some tutorials on net for v ray ..

But thing is it took around 3hrs n 30 min to complete the render ...

Need some Ciritcs, Suggestions on how 2 improve this ...

n one more thing, I'm plannig 2 increase the memory right now my system config is p4 3 ghz, 256 MB DDr n NVIDIA Ge force 6200

Welcome to the site Kishore...nice start with vray

There are some scale and mapping issues here...like the scale of the sofas and the floor tiling. What size did you render the image in...the time is too high if it was not a hi-res file. If you post your settings here, we can tell you how to optimize them!

Nice first post Kishore

as Neha mentioned above there are some points that you can work upon for the next update. Otherwise nice first render with vray. Which version of vray you are using?

Hi Neha ... thnx... hmm the sofa's are 2' high .... mm and i rendered the image at 1152 x 864 .. not a high res precisley ... n way .. I'm attaching the render settings. But i have used v ray 1.09 for the rendering and presently I have installed . 1.47 .. but I see the settings I have used are still existing ...

Hey thnx .. pradipta .. surely I'll try improving on it .. I used .. v ray 1.09. but now i've installed .. 1.47.

i was going through the settings you used. Dont ever use Noise Threshold as 0.0 under QMC Sampler. it slows down the render extremely. that's the main reason why it took so long. it should have been over under 1.5 hour in that config. 0.005 gives acceptable results in most cases. Catmull-rom gives more sharpness rater than Area, specially in case of interior. your IR map min/max can be around -4/-3. try this setting, i think that will do. that's all, mate.

Kishore, yes, the noise threshold setting was what caused all the render time! Once you start using vray regularly, you will develop your own style and find the settings that best work for you.

Here is one post where you'll find a lot many tips to optimize your render times.
