Elvin Aliyev’s 3d recreation of Tadao Ando’s Church of the Light and adjoined Sunday School extension is one of the best made and look better than any photo I’ve seen of these projects. His render set showcases the design in a remarkable way with his attention to the materials, camera placement and light which shows great respect to the work of the master that Ando is. Now we can have a glimpse into Elvin’s work process.

Introduction

I started the 3d recreation of Tadao Ando’s Church of the light for self-education purposes only. After some time working on it, I took a long break and returned later as part of trying myself at an Evermotion competition.

The experience that I had during my work on the “Church” cannot be compared to anything I’ve ever done before in the realm of 3d architectural visualization. This only made me more eager to share this experience with you all… hoping it will be useful for you too.

And here are some of the finished renders I made…

Modeling

The modeling process of the “Church” was pretty easy. I’ve found a pre-made SketchUP model over at the 3d Warehouse and did the rest very quickly.

When it comes to the details, like organ or a floor lamp, I had to do them based on reference images and this part of the modeling took some time. There is an overload of photos for this project online and so finding the right ones was just a matter of putting in the time, prowling it all.

Here are some reference boards I made…

Helping me with the initial SketchUP model cleanup was a very basic plan, and it did not take too long to have a general model ready for texturing and further development.

And the basic model within 3dsmax ready to go for more advanced work…

Here are screenshots of more specific elements that were modeled for this project…

Here a more specific one showing some hint of cables going down from the microphone stand… it is not 100% perfect, but it doesn’t have to be – just what shows in camera is ok.

There really isn’t that much to the macro modeling of a Tadao Ando project… it is all in the play of light on the materials – in 3D, much the same as in real life too!

Here are some overall views of the model…

Textures & Materials

This part of the work was the most complicated one for me during the making of this project… being able to make qualitative materials and textures. 10GB less on my HDD and hundreds of cigarettes later I accomplished that… I hope.

Here a final image showing an area with both woods and concrete…

I used Arroway Textures for the concrete and wood which I mixed up with various other textures from cgtextures.com for the dirt and blur effects. The concrete texture resolution was a large 12000pх X 5000px and I had 4 of them (2 for the Church and 2 for the Sunday School).

The wood textures resolution was 10000pх X 3300px each. I used these big sized textures only in the diffuse channel though… I reduced the other maps to be 2500px wide (bump, reflection, etc.).

Why? Because it saves resources and helped with a little side effect I needed of blurring the reflection map a bit. When you make the reflection map smaller 3dsmax diffuses it a little, so you get the needed effect.

It also should be noted that I practically don’t have objects without textures. I don’t like doing an unwrap and drawing a texture on it in PS. That’s why I’ve been using the VRayDirt everywhere it was possible to overlay dirt layers on top of the clean texture version.

If the object was bright, I’ve inverted the normal and made the dark corners, and if the object was dark – vise versa. Bright and dark materials have one main difference – to get the realistic look of a light material is much more difficult. So, I’ve used 3 wood materials for the church and 8-9 different wood materials for the school. Textures can be the same but you have to give them different reflections, colors and glares. In some cases you have to mix them to get the right effect given the light that falls on the surfaces.

The Concrete

The concrete materials are a blend of clean texture maps from Arroway Textures and various stain, dirt, etc. maps gathered from cgtextures.com. You can hardly ever use a clean ready-made concrete texture and pass it as a believable one… real life is much more complicated than that. Concrete tends to show the marks of time on it more than other types of materials and this aspect must be addressed to get as photoreal as possible.

Here’s a detail shot focusing on a concrete intensive corner in the project…

Here is a collection of the maps that I used during my work on this project…

Arrow Textures offered a great base to start from with hi-fidelity detail that will show great up-close. Using VRayDirt allowed me to overlay various other maps to mimic the natural patina that any concrete surface gets after some time.

It is important that for the base you get high-resolution & high quality textures, but for all the rest you can work with pretty much anything, resizing, cloning and hand paint it in.

Here is the concrete material node tree view…

Here are some of the nodes in greater detail…

I layered the textures in Photoshop so that I can mix them up… although, as mentioned, this was a very small impact process. Most of the layring was done inside 3dsmax using VRayDirt maps.

Here the mix of the original clean concrete texture and some dirt to form a more real looking diffuse map to be used as one of the various concrete version made for this project.

The Dark Wood

Unlike the concrete textures, I had to work more manually here. I did not look for too much dirt & scratches maps for this one… I did them myself in Photoshop using the small brush for scratches and spots and the large brush for the larger bump detailing. As I’ve said before, I’ve used 8-9 materials for the textures of the church & Sunday school.

Here’s a close-up shot on the dark wood benches and flooring…

The dark wood for the bench was based on a very bright wood texture map that with some paint work turned into what was needed…

Paper & Books

You won’t find anything white and 100% clean in this world. VRay actually helps in that regard by producing noise and maybe not so clean GI solution when using lower render settings (pretty cool as it saves time and promotes the photoreal look). Even so, I mixed it up a bit anyway.

The most difficult thing was to find the books (especially religious ones) in Japanese. I ended up translating some pages to Japanese as I didn’t want to make too much of a focus on books anyway.

Lighting

Lighting such a dark interior is not so hard as you might think… You just put skylight portals with the “simple” option enabled, thus ignoring all outside elements that might affect the lighting going inside (this cuts calculation times) taking only the sky map lighting into account.

If you don’t have anything outside the window, you can disable this feature.

Using a VRayDomeLight with an HDRI assigned to it, doesn’t make too much sense for the interior, but for the illumination of the exterior I’ve used it with one of Peter Guthrie’s HDRI maps which I find are very good.

In general, the illumination is a very delicate matter, you can’t use the same methods and you should be careful with textures – don’t lighten or darken them too much, even if the floor is rather dark. make room for some adjustments in the postwork stage… better that than re-rendering.

Here are the lights used in the scene…

And the lighting settings…

Rendering

The render settings here are very simple. Just take a look at the settings in the screenshots below…

Postwork

I saved of the renders into *.exr so that I can open them in Adobe After Effects and use PHOTOLOOKS, MSFIRE and COLORISTA plugins (by REDGIANT). I actually didn’t use Photoshop for this because it has several restrictions when working with 32-bit photos.

Here are some raw renders for show…

I used FRISHLUFT for the depth of field effects, as I find no sense in wasting time and render this effect with the built-in DOF in the VRayCamera… however good it is.. I also used MSFIRE for the vignette effect, as it’s flexible and reconstitute the needed effect more accurate. And, of course, PHOTOLOOKS fasters processing, simple and flexible post possibilities and the steady habit it introduces to any kind of effects. The process takes less than a few minutes, if you’ve done everything right.

Here are the settings screens if After Effects (not much explanation here, i know… but feel free to ask whatever you like about it).

Conclusion

That’s all! I had great fun describing my process here. I hope you found this information helpful… Feel free to ask anything by commenting below!

My best regards and gratitude goes to Mr. Ronen Bekerman for his excellent blog.
