Introduction
show user profile  dcny30
Hello all,

My name's David and I'm a new addition to this forum and a quick introduction before asking my question.

I'm an architectural renderer for a small architecture/interior design firm. I do mostly interiors with some exteriors. I use 3DS Max version 9 with vray. I'm based in New York with most projects here as well. I took one course in 3ds max during college but really learned the craft working for a rendering company for 2 years before working here for the last three years.

My question is there anyone here with a good/strong understanding of vray and the rendering process? My work is very time sensitive and often under very high stress to finish my work for a deadline. I have some questions that relates to VRay. I'd be happy to supply more information if it's necessary.

I usually cheat with the modeling - downloading from various websites to save time so I can really focus on lighting and getting a realistic/accurate look that the architects/designers are after.

Thank you,
David.

Hi David, and welcome.

There are many Vray experts here. I hope you get the answers you need.

Downloading isn't cheating! I use loads of stuff from Google Warehouse and Turbosquid.

sourcing models from an external source aint cheating.
As Nik said, welcome to the forums. You'll generally find the answers you need here if you ask specific questions. Chances are someone will know the answer.



He who says it cannot be done is interrupting the man doing it.

Many thanks.

My question is primarily the vray rendering settings. I limit myself to 1000x1000 that will be printed on either letter size or tabloid size. Sometimes as a PDF to be emailed out.

The max files vary greatly in size and degree of details - I use matte materials wherever possible and rarely use glass. I sometimes use reflective metals and stones. I also try to limit myself to vray lights as much as possible and make up the difference in photoshop.

I tend to use the same vray settings over and over regardless because i'm not well versed in all the options. And sometimes i just don't have the time to fiddle with the settings.

My settings:

In indirect illumination - both reflective and refractive are unselected. Primary bounce is irradiance map, secondary bounce is light cache.

Irradiance map:
Current preset is either low or medium
Show calc phase and show direct light are selected

light cache:
subdivs is usually 250 or 500
store direct light is unselected.

Is there an option or selection that I'm missing that can make a difference - an area that i can explore? Or am i better off getting a tutor? I realize that the settings for the vray is vast and there are tutorials to help out. I'm actually asking for personal experiences which can't be found in a text book.

I'm more than glad to add more information if need be.

David.

Hiya there, welcome. :)

Best way to get the right help is to post up some pictures of your current 3D work. We'll know where to start with ya then. ;)

in general, your in the right mind set for doing arch viz work. irr maps and adap subdivision is the way to go for large/flat/clean surfaces. you loose detail but most of the time in arch viz, that's not the point.


outside of that, as mentioned; post up images for specific problems if you have them and use more glass!!!

Roughly speaking, there are 3 ways to use a renderer:
- using a number of well known presets. If they get you where you want to go, there's nothing wrong about it.
- playing with the settings, preferably in isolation at first, to gain an intuitive knowledge of what they do. This can bring you quite far and will give you a lot more control over various aspects of your renders, including render time.
- the geek way: learning in depth what each and every setting does and how it does it. Just a few hundreds hours of hard work will give you total control!
I guess it all boils down to what you need/want and how much effort and time you want to invest.
You could start with the doc, working your way through each topic and experimenting with the settings.
If your company can afford a few bucks, have them buy you this book. There's nothing in it that you couldn't find by yourself but there's also very little not in it.
There are several articles floating around about more specific subjects, like gamma and linear workflow, the DMC sampler, etc.
And then there's maxforums: the ultimate knowledge base. From friendly domestic whales to fronats and 3D web browsers, there's nothing we don't know about (as a collective).

Welcome!

Thanks for the bits - I appreciate it. I figure if I want to know more - I need to devote time to it - often I don't have that luxury.

I avoid using glass because they take so much time rendering. I know that it'll make any space look more realistic but again time's not a friend.

My boss and co-workers don't comment on the lack of glass in windows so I figure I'm okay there. They mostly get stuck on lighting, details and the colors.

I'll post some images that I have the most trouble with and maybe that'll help out.

The book sounds like what I need. I'll look into it.

Thanks again,
David.

I will surely tweak irradiance map subdivisions. Try 80 or more Hsph to obtain a cleaner look. Composition and light denotes some sensibility.
I would add an AO dirt pass, give extra love to textures (i.e. avoiding sofa textile repetitions) and add geometric details here and there.
Good ones, in general.
