Hello everyone, I would like to seek help and some guidance on creating a material as seen in the attached reference image in vray. I tried a black color diffuse and few scratch and patches Black white textures in the reflection slot but I am not able to achieve the desired effect. Any help is appreciated.

Thanks

Hi,
I don't think it is possible yet.
They introduced fog for aerial perspectives but it's not the same and limited to sunlight.
There is also this material called Subsurface Scattering that has some volumetric options etc. but i doubt it can be used for your purpose.

Thereby, you can try to add it in post production

Thanks for information. You are right... Post production is the way to go for now.

Hi,
I am working on an interior render of a small theater where I would like to render the light from the projector and screen. For the screen I know I can use a bitmap and make it an emissive material. But I have not clue who I can render the light from the projector The view is from the back looking at the screen. It will be really helpful if someone can share how they achieved the same with SU + Vray.
Thanking everyone in advance.

Cheers !!

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.

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...

Droppel, thanks for your kind words. I would like to improve upon it.

Hi doppel,

Attach is an office interior render for your comments.

Thank you

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,

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.

Hi valerostudio,

I got better results with AO turned off but still there are strange spots on the ceiling and lost the depth in the rendering with AO turned off. Can you please suggest what would be a best starting point for AO setting in a rendering which have fine moldings ? or a way around it ?

Thank you.

I have VFS 2.00.23590 installed on my system. Please let me know if there is any other information i can provide which would be helpful.

Thanks
