Questioning & Considering…
Looking at the picture in the previous post, I have had to ask myself: would there be walls of a different shade/type of concrete in the structure of a hotel?
When I look at the images of the shanty buildings I see different shades of concrete all over the place as the building has been modified and built upon or maintained with what is currently available rather than a duplicate of the original material that might be too difficult or costly to source.
When making a new building like a hotel the concrete will probably be mixed either on site and poured into plywood mouldings or created elsewhere and shipped in, in either case the mixture and type of materials should remain reasonably consistant.
Therefore, I think that to create a realistic looking building, I will need to use a wide variety of textures, BUT have them colour matched to a single image so that they all look like they belong to the same set. This will give the image the consistant look and feel that I want yet retain the natural randomness of the texture of the concrete that would be found in the real world.
Having looked into just using a variety of bump materials, this creates the finish that I want. Painted uniformly, but with a different concrete texture to create a real world effect. The other textures are good and look good, but are too dirty for use with the hotel.
The wall moved forward shows the style of bump texture that I intend to use. I will use a range of different textures to minimise the perception of pattern repetition in the final render.
Building Materials In India
During a tutorial a while ago and more recently in my last presentation I was reminded that the most common building materials used in construction are the ones that are easily made and found locally. Which makes natural sense once you realise. I found myself choosing materials for the hotel that I am building and I was about to add some decking to the balcony floor and I stopped. Is decking found in India? Does India use wood in this way? Would it be found in a hotel? Would it be found in the locality of Banares/Varanasi? The brief answer is no! All the images that I have of the Varanasi and Calcutta show that concrete and stone are the most common forms of building materials in this region. To support this I found a book about the subject and this supports my assertion. The book also showed me the common materials used generally.

Choosing appropriate materials
The centre and left partition walls show the concrete material the flat yellow of the remaining structure is the original stucco render that only shows its texture when the camera is close up, which is unlikely to be the view in the final renders. So the concrete texture is an improvement. I am going to need to scale up the texture a little to enable me to prevent patterning in the texture on each successive wall. This was clearly evident in the first project and I want to prevent it this time. This will help bring a more realistic feel out of the final renders which was absent in past.
