Making of Loft

Matheus Passos created the Loft scene as a personal project inspired by the works of MIMO Studio and Insomia Architects from Poland in tandem with the 2011 Forum Summary – as an entry for it. He did a great job on this one, managing to achieve high levels of realism… especially in the detail shot you see up above. Read on as Matheus shares more information about his workflow in the creation of this scene.

Introduction

The work on the “Loft” scene was carried out in tandem with Ronen’s 2011 Summary on the forums, and inspired by the work of Insomnia Architects & MIMO Studio from Poland. I loved the Loft project very much and decided to give it go myself… modeling and rendering it.

Units

Working with good reference plans is very important, and keeping within real world units (no matter what you use… mm, cm, M) and have all elements scaled and proportionate to the scene. Here is my units setup.

Linear Workflow

I usually use LWF in my work, although it seems many have their own take on what LWF (Linear Work Flow). There are several tutorials on the internet where you can read about it – one of the best was posted on this blog at Linear Workflow Made Simple by Matt Gorner.

Modeling

Before I begin the 3d modeling, I prepare a 2d blueprint lines model serving as a base. I then use extrudes to push this base into 3d form and further detail the structure adding bevels and chamfers were needed to enhance the look.

loft-modeling-before

To create the wall openings I use a method that some of you might consider odd – I use Pro Booleans for this… For me it’s the easiest way.

loft-modeling-after

Here you can see how a small chamfer is used to soften the edges of the wall that aren’t perfectly sharp in real life.

loft-modeling-chamfer

The floor was modeled using the great Floor Generator plugin. It has been featured on this blog so many times, and for good reason! Check out Bertrand’s write-up about it at Using Floor Generator Script. It would be nice to see this work on vertical surfaces (or any other type of surface) too.

Lighting

The main lighting source for this scene is a VRay Sun that work in tandem with a VRay Dome light loaded with an HDRI map.

I also added VRay Lights as Skylight Portals to the wall openings, to help with the faster calculation and light spread in the interior.

You can see my lighting setup below…

loft-light_mini

Viewpoints / Cameras

Picking good viewpoint… good compositions is super important , and so I setting up the cameras. I use the VRay Physical Camera due to the correlation with real-life camera settings.

Notice the color balance tweaks I made due to the warm nature of the scene having lots of wood… I use WB to counter balance that for the end result.

loft-camera-WB

I great advantage we as CG artist have vs. real world photographers is seeing behind walls! Like Superman!!!

You can only push the wide angle so far before it looks way too odd and you still did not capture enough of a given room. Here’s where the camera clipping plane feature comes to your rescue.

I place the camera outside the room behind the wall and the clipping plane was pushed forward just so I pass that wall slightly and so uncover the room interior for the camera.

Furniture 3D Models

Many people asked me about the furniture I used in this scene. Did I model them myself, or purchased ready made models?

Well… there’s nothing wrong with buying ready made models (as long as you do keep trying modeling some yourself, perfecting your skills… you can learn a lot form the works of other this way).

I did some shopping prior to my work on the “Loft” scene, and tested the models in it. Some of the 3d furniture models were made by Bertrand Benoit (BBB3viz). He is a great inspiration to me and his work is of the highest quality in our industry.

I also used 3d furniture models by designconnected which I like to highlight here. Using them for the first time I was very glad to find they were well modeled and have great realistic quality… in textures too (even though I tweaked those for my own purpose and taste). They are also very affordable, which is super important for me and anyone else I assume. The balance between modeling it yourself vs. buying them depends on that greatly, so this helps.

In this experiment I found it very important to use professional models, which made ??my work faster. I used 5 DC models : Cityloft Sofa, Lanshire Clock Works Dancer, Ligne Roset Africa, BD Barcelona Flamingo and an N/A Pendant Lamp.

I used the MultiTexture plugin for creating the variation in the floor wood planks.

Rendering

Here’s the viewport camera view selected just before I went to rendering the final image…

loft-viewport.jpg

You may find that the irradiance map method quality is low, but it can be easily solved if you increase the number of the global subdivision multiplier…

In the original rendering I used the value 3. But I re-rendered with the value of 8 which gave me a result of walls without spots…

loft-render.jpg

I might have started to low, but this is none important… what you need to know is that you can and should play with the settings to learn what they do and thus better optimize your rendering process (or get a monster computer and just use brute force… even then you will quickly demand more of your workstation, since we always want more – so learn to optimize).

Here is the new render with the global subdivs multiplier at 8…

Post Production

I did very little post production in this project and aimed for getting it all done in pure render as much as I could. I do output some passes just in case I need them, but mostly do a few color corrections and that is it!

This is how it came out the renderer.

loft-cam-001-raw.jpg

And this is the result of post-production. To simulate the light from the lamp I used Magic Bullet for Photoshop.

thank you so much for the tutorial..its amazing

can you tell me the length and width of the wall please???

people should focus less on great renderings and more on great design. the obsession of the image of architecture is ruining the field. architecture is imperfect. and architecture is for the user.. which is so often forgotten and the rendering obsession is just one cause.

Indeed, I felt bad after following the link. Maybe I wouldn´t even comment If I actually clicked it before, but here´s the catch: how many people do like or comment based only in the post image, thus associating his name with the composition? Anyway, no action asked, it´s a good tutorial. Thanks for your kindness, it´s a great job here and with the site.

i guess i'm too used to GI splotches to think they're anything else but you have a point

Yea, Known issue with this one... but I find it adds to the "used" look of the space ;) (same way as having a bit of noise in a render makes it look more photographic... funny, but sometimes low settings are a friend)

nice one, but there are GI splotches pretty much everywhere.

Hi,

It really look great. Can you tell me which HDRI map you used? Was it a cloudy picture? Btw, Link? Thanks, Tomas.

hy !

thanks for these post , it was very helpfull for me ! :)

i have just a question : i saw you used the 1313 cloudy tiled hdri from peter guthrie,

can you tell me the values you uses in the vrayhdri map? (orverall et render multiplier)

nice rendering~~ unforturnately i can't use floor generator. i already put the scripts file into the fold , but everytime i start 3dmax it is said "MAXScript Auto-load Script Error"

Hello Matheus, congratulations for that extraordinary work. I'd like to know How much would I have to pay for a work like that? I'm really interested in rendering. Thank you very much.

Hi Matheus , Nice tutorial and thanks for sharing it.

Some questions. Why do you not increase your HSphSub instead of increasing your Global Subdiv Multip (8 ???) to avoid your "Spots" ?

I've tried your settings on one of my scene. I've to abort it after 8 HOURS !!! (without finishing)

I Think your Min Samples and Global Sub mult are much to higher ( even for a i970 6 cores).

Cheers

Really inspiring work! Great mood.

But in my opinion the splotches/spots (whatever you called them) are really apparent on some of the renders. 

 

Question:

Could you explain to me all those falloff nodes on the sofaMaterial. Why and how do you use them, being a Maya user I would really like to recreate a similar result.

 

Thanks for sharing your workflow!

Hello! It looks fabulous! Someday I hope to have this perfection! Allow me a question from novice user: how to apply the texture to the books? Do you use multi-subobject or exists some other method? Thank you for your time and your knowledge! Cheers!

Hi, ronen how are you?

 

is it possible for you to make a litle tutorial about This Couch Modeling? texturing?  Or

How to make those wrinkles? im having some Problems how to make them looking good..

 

i would like that if you make Some Short Tutorial :)

 

Thank u!

Very nice and clean, it remainds me Architectural digest look. may i ask what material setting did you use for the white walls? 

Congrats again

Nicely explained @MatheusPassos  , only thing i would change is up the hsph subs of the irradiance map so there would be no GI glitches under the ceiling. All in all some very good light and visualization. Thanks for sharing your knowledge. ;)

Great Work !

How long did the  render take ?

i see some splotches but it doesn't affect your render, maybe you should test Bruteforce next time to avoid them.
