Forum member Vladislav Dechev (graffitiman) posted an interesting set of renders of the Tobacoo Company Headquarters in Sicuan, China. The design has a unique look, with a green roofs emerging from the ground covering the structural elements. Vladislav was kind enough to share a few aspects of the visualization creation. Enjoy.

Starting with the roof

It was a challenge to model the green roof of the building, and since we’re working with ArchiCAD most of the time (doing the actual drawings) we also used it for building the 3d models.

It’s almost impossible to do that type of structure in ArchiCAD though, so I took it into 3ds max. Using splines and adjusting the Bezier vertices I’ve built the contour of the roof. (1)

After that I applied an Edit Mesh modifier to it, followed by Shell modifier. (2)

Then by using a reference of the initial spline, I’ve easily created the curb around the grass with the Sweep modifier. (3)

Then I exported the 2 meshes as .3DS and imported them into ArchiCAD using it’s free add-on “3ds in”. (4)

I needed that mesh inside ArchiCAD because I was going to build the entire building there and I needed something to cut the walls with. The “3ds in” add-on works perfectly. It converts the initial model to a .gsm library part. It also keeps the different meshes apart by giving you options to apply ArchiCAD materials on them. (5)

For most of the walls I’ve used the “Profile Manager” inside ArchiCAD, creating them from just a few fills, which get to be extruded later. This way you have only one object instead of 20 and It’s easier to work with it. (6)

On the next image you can see the entire model put together in ArchiCAD and ready to be exported back to 3ds max. This step was done trough .3DS file which was imported into max using the ArchiCAD Importer script by Mirza. This one gives you the ability to update your model from ArchiCAD without losing the already applied UVW modifiers and materials in Max. (7)

In 3D Studio Max I used a VRaySky in the environment slot, linked with the a VRaySun. (8, 9)

I also used a VRayPhysicalCamera with settings you can see above. (10, 11).

In terms of materials I used VRay materials only. Here’s an example of the Marble (used for all walkways). (12).

The vegetation is done using Onyx Tree (for the bamboos) and for the broadleaf trees I used Evermotion licensed models. There also some benches and street lamps. All of them are converted to VRay Meshes and the Proxies are spread using the Advanced Painter script. (13, 14).

Next you can see the VRay render settings. I’m usually using very simple ones. The most important thing here is to add some Render Elements for later usage in Photoshop. Absolutely necessary is to save the rendered images as 16 bit tiff (or other format that supports 16 bits) so you can play with the highlights/shadows without losing quality.

Here’s one of the Raw renders opened in Photoshop. The final resolution was 3000/2000 pixels. On the right side of the image you can see the layer tree, not many adjustments, just some very basic color corrections, DOFs and some Levels. (15).

For the DOF’s I used the ZDepth render element from 3ds Max. And since its a 16bit image you can adjust the levels on it as you need. (16).

For adjusting the color of the highlights I used VRayRawLighting map applied on a color balance adjustment layer, also on levels layer. (17).

And for the shadows, a VRayRawShadows map with the same type of applying. (18).

Next are some of the adjustment layers options. All done differently so they could mix perfectly with the underlined imagery.

And here’s the final image.

I hope you enjoyed my “Making of” – Best Regards, Vladislav Dechev.
