About

My name is Saksham Kumar and I am a 3D artist who lives in Delhi, India. I am 16 and currently a student. Cars are my passion since childhood. My family also loves cars and that is where this love for them came from.

I used to draw 2D cars when I was 8 and since, my passion has grown into recreating cars in 3D. My first modelling experience was with a Fiat Uno, then the Ferrari 812 Superfast. I also rendered a few others which were not modelled by me but I textured and materialised them. I love the visualisation aspect the most and have rendered many objects and cars since my introduction to Blender in 2015. Blender feels like a natural home to me due to the workflow and shortcuts. I stuck with blender 2.79 for this because i was not very familiar with the new UI and also because my GPU is not supported anymore (RIP PC).

The tutorial I stumbled upon

I saw the CG Masters Master Car Creation Tutorial and set that as a goal for myself. Chris (Tutor) was very helpful and provided many tips and tricks throughout the course. He guided step by step so that even a beginner would be able to follow the tutorial.

The most helpful advice that changed the way I model was using a guide mesh and shrink-wrapping the actual panel to it. This helped me create smooth reflections throughout, even with cutouts, without worrying about them in the final panel.

Creating the Base mesh was smooth sailing. We just had the reflections to worry about. Ignoring the cut outs and all. Here is a shot while creating the base mesh:

Here are the guide meshes:

Shrinkwrap modifier physically moves the vertices on the final mesh to correspond to the guide mesh. It helps to create the same reflections as the base mesh. Additional meshes were also used to smooth out or bulge reflections in certain areas like the front bumper.

My favourite part was modelling the wheels. They were kind of complex to model but also really satisfying to do. There is also a free tutorial of the same course on how to model wheels.

The lights were also a great one as they looked very realistic and were not as hard to model as I expected they would be.

Here is the material setup for the lights to create those realistic clear plastics and reflectors.

Adding shadow planes hid the non modelled surface pretty well.

The brake disc material was a very complex one. But the results were amazing.

Next, my favourite material, Chris Plush's car paint material, inspired by Mike Pan’s Car paint material. It had orange peel, micro scratches and emulated a perfect real world example. It had controls for metallic flakes, clear coat , base colors, etc.

The interior was a really bare bones basic one because it is really tedious and tiring to model it.

Now, the camera and rendering

There was no way that my PC would be able to render 4K 2000 samples and so much data at the same time [Refer to end of article]. I used GarageFarm to render the images. The support is very helpful and you get results very fast. My PC would have taken days but they took only 20-30 minutes each for full 4K 2000 samples images.

Camera Settings:

Render settings:


I still ended up using denoising because FIREFLIES.

Composite settings:

I removed the dust overlay because there were some scaling issues.

I used the famous Warehouse HDRi for this one.

Raw renders:

Edited in Lightroom:

Added some lens overlays:

Clay render:

Tools Used

You can buy the course on Gumroad.

Garagefarm is a great render farm that made this project happen.

I use a Core 2 Duo E4500, GT430 1GB, 2GB RAM, 120GB HDD. Basically imagine the slowest computer you used and decrease its speed by half.

I am very passionate about CG and the one thing that holds me back is my PC. The average time would have been reduced so much for this project if my PC was fast. The message I want to give is that I would love to be sponsored and CG is one of the most important things to me but due to hardware limitations, I am not able to pull off projects like these. Everything is slow for me because of it. It is the lag city you never even would have imagined.

Thank you for your time reading this article! I appreciate the opportunity that BlenderNation has provided. Also, check out these links!

  1. Really nice results like I mentioned on blenderartists! A couple quick corrections though: It's just "CG Masters", no correlation at all to CG Cookie. Also that's not Mike Pan's car paint material, that one's mine. I learned a few things from Mike about car paint so I just gave him a shout out in the course.

  2. Yeah, I sure will, And I am extremely sorry for the mistake. I was just a bit confused. Also, the paint was just appended from the final .blend file and looked really similar to the Mike Pan's so I forgot that it had a few changes!

      • CPU support for 64 bit architecture only means support for more than 4GB of RAM. Putting a 64-bit OS is not only pointless in your case, but also harmful, since such an OS and 64-bit software consumes more RAM.
