Buildings and fascades done with City Engine

This is the first building from a series I will create and it can be found in Hamburg Speicherstadt. It contains a lot of 3D elements created in Silo. Working with those elements, called assets in CE, is very tricky.
I've divided the building into columns, where the tower sections have relative distance values. This is the reason why they are stretched in the render pic. The door and window pictures are from goodtextures.com which is a great resource for all kind of textures.
Attached is a reference photo and the rendered picture.

looks good, man.

Oh my word, that looks fantastic katto! Here I am struggling to make a box with windows and you're building like an architect! How customisable is the building? Presumably you can make it taller and wider? Rep if it will let me.

Stunningly good...

Thanks a lot.

Ravs, after looking at many pictures of the area, I saw that the smallest unit of the buildings is a column. So I've started with a split(x) first (btw it is better to start with that split when you have complex buildings, the ones in the tutorials are simple and have the same features in each level, so they start with split(y)).

You can rearrange the sequence of columns, but the building layout in reality is always (ABCDCBA)* + corner buildings. The B and D columns have a flexible width to fit in different lot sizes. It is not possible to change the height because of different y splits in the columns.
If you have further questions feel free to ask.

Another building is finished.

This is just really cool Katto!

I must get back to City Engine....Katto thanks for the tips, but I don't think I'll ever get as good as you!

Thank you.
This building nearly has the same dimensions as the first one, but a lot of more complex objects in it.
Now I try what can be done with streets and sidewalks. Here are some quickies:

Holey moley, are you using Vue for the renders here?
