Vray Office Interior
-
Hi,
Can some one please recommend a good rendering tutorial for an office setup?
I have seen some where there is some sort of natural light.
I work in a firm which does offices which have many interior spaces with no natural light. What is a good starting point for such conditions? How would you approach this?
I can share few sketchup files if someone would like to take a stab at it?For me I play with the physical camera setting and have few omni lights in it. But the results are not good
. I am not looking for a super photo realistic result but most of the times my render has hot spots due omni light. I did try using IES lights but due to number of lights in the scene it just kept crashing.Thanking you in advance for your inputs and your time.
A newbie, willing to try, fail, try and learn.

Unfortunately there are not too many tutorial on totally enclosed spaces. In an office setup esp where there are rooms with no windows, nice ies lights right under your lighting fixtures (downlights) should give you enough illumination. well, you really have to simulate lighting somehow if you are designing workspaces although lux calculation is done in other softwares. But just for presentation you can add fake lights (vray rectangular lights just to illuminate the areas you want to highlight and compensate for the dark areas. Truth of the matter is its not easy to illuminate a space without natural light. the color, maps and material properties including light and material subdivs, light bounces will have impact in the overall illumination. These you need to balance. if youre new as you said, there are tons of downloadable models vray-render ready. you can start by studying these setups, reuse the materials (vismats) and settings (visopt). That by far had been the most effective way for me..then study the rest along the way until youre able to setup your own scene.

Hi,
cuttingedge gives you good advices.
can you post a render so we can check what's wrong ? -
Thanks cuttingedge. You are right, I am finding it difficult to balance various aspect of the models, details, maps and lighting. I will try downloading few vray ready models and study them as you suggested. Can you please recommend a good source for it? I have tried using ies lights in past models but my render would always crash and i had to opt for omni lights. Once again thank you for your inputs. Appreciated.

Hi doppel,
Attach is an office interior render for your comments.
Thank you
-
nice render. the lights are quite good.
-
Droppel, thanks for your kind words. I would like to improve upon it.

As a matter of fact, our eyes (mind) works differently from photos or computers. i.e light attenuation is based on inverse square ratio, but when one adjusts them in this way will find it more like what a camera captures and not what our eyes captures. So I've experienced that it will give a better result if adjust the attenuation as "inverse". the result will be more smooth and less contrast ,a better solution for interiors. and do not neglect some fake lighting using rectangular lights, here and there ...
.
a minor comment on this render: place lights inside their place: tube lights that you have modeled. and also maybe it would be nice to model some more "place holder" for other lights... -
Thanks Majid for sharing your experience.
I always leave the default setting (except intensity) for Omni lights whenever I use them and at default the decay is set to inverse square. I will try "inverse" option in my next rendering. I have tried putting lights in the modeled light fixtures but due to their number (roughly 120+) VRay keeps crashing.
Can you please clarify what you mean by modelling "place holder" lights?
Thanks once again for all your help, appreciated.@majid said:

Simply creating an emitting material could do the trick. Replace glass of the lights with this material. Maybe that helps?
