This is a project that I was originally involved in years ago, while at GMJ design Ltd.
I have had to remodel most of the architectural details for the sole purpose of this exercise!
The idea started years ago when I first pleaded with Matthias ( then, working as a Director of product integration, @ mental images) to develop a plug-in that could aid professional 3D Visualisers to integrate their 3D elements into Photomontages; verified views and general external shots!
Then, I used to struggle particularly with external daylight scenes.
My desperate plea spurred Matthias to single handily develop a ground breaking plug-in that is now known as RichDirt.
In addition to being ultra-fast to render, it also provides users with a variety of options to plug/ mix with other proprietary shaders, and a variety of Maxs procedural maps such as cellular, smoke; Mix; Noise; Speckle; etc.
It is currently designed for Max/ mental ray only. However, since users can efficiently output its effects as multiple elements (i.e. rendered passes); it is possible to overlay the elements in post, whilst using other rendering engines (i.e. Vray; Maxwell; FPrime; etc).
It is also worth mentioning that it is currently being developed specifically for Vray, Maya, Maxwell, Cinema4D; etc.). So keep an eye out for it.
Having tried and stress tested the product, personally, I find it to be the best suited product to address the technical nightmares highlighted earlier.
In fact, there is an in-depth article/tutorial about its core functionalities:
I hope you find the rendered results interesting!
