@ntxdave Started from a concrete texture and modified it using an image editor (Photopea)

@ntxdave I made the texture and applied it to the walls, some part is not textured properly and I will fix it.

I modeled the building, textured and rendered it to try the exterior scene. Texturing needs more attention and I will rectify it later. By the way, I liked the result.

@ntxdave Ah yes, you are right my friend. Here is the link

Just messing around with the Prome ai sketch-rendering tool.

Another patter that provides natural light and ventilation using masonry roofs in a modern look.

@ntxdave
Maybe an alternate solution works.
Make a component composed of two components, one very simple as a line (this would be our place holder), and the object you want to scatter. Separate their tag (layer) and hide the "complicated object's" layer (tag).
Now it is time to scatter the simple (placeholder) one.
It could be done using "component spray" plugin, I think.
It must render fine in RS, I guess.

@Mike-Amos : While reading the story I was waiting for an epic ending like cat pissing!

I edited, modeled and uploaded one of the sketches as a villa here:

@ntxdave Thanks Dave for your compliments, this is a matter of exercise.

More sketches :

Here are some of them:

@ntxdave
As the internet speed drops sometimes I cannot share those sketches here. I think those sketches are not involved in my book and that is why I shared them.

Just recently I realized that I have dropped some sketches and here are some of those ones all based on the letter "A":

Thanks for the compliment. I am still experimenting with the coating layer and maybe am not using the right template but the result is amazing.

@pixelcruncher My pleasure to have my hands on such a charming piece of software. Considering my laptop is rather old, not supporting recent graphic cards and all the computation is done by the processor.
Here are more tries to discover the "coating" layer .

Another variation of the vaulted roof from my book:

Thanks Thomas.
I shared the model so that everyone could play with it. The brick texture is of low quality, so please replace it.

Spared some time to try an old model using RS. May I ask. for "fake emit" to get it back please?

@pixelcruncher Yeap it makes sense if is in front of its name. Much better if could be undocked , floating and enlarged.

@pixelcruncher Ah I did not noticed the "square" as an "image place holder", Thank you...
