From his home base in South Africa, Sebastian, also known as TruForm, has learned by trial and error how to create the highly detailed 3D models for which he is known.
"I'm totally self-taught," he said. "I haven't done any 3D courses whether by attending classes or online. Just a few tutorials and a ton of failed projects -- OK, make that a megaton."
But it's not like he came to the computer with no artistic skills.
"I'm the kind of person that will draw on the reverse side of an invoice if my passion so directs me, and possibly my way of saving trees," he said, pointing to his Renderosity gallery as an example of his passion for creating art.
He started working with digital images on MS Paint in the mid-'90s but expanded his skill set with 3D after finding a free trial CD in a computer magazine.
"I think that was around 2007," he said, adding he got tired of recreating the same scenes with the limitations with DAZ.
"I wanted to create my own scenes. It was at that time I got into creating with different 3D programs," TruForm said.
Now he creates with Blender 3D.
The open source software gave him the flexibility to create models. Eventually, the Renderosity community encouraged him to start selling his creations. Now he is a top seller and was named Vendor of the Month for May 2017.
TruForm said he most enjoys designing room interiors and cars. In fact, the piece he is currently most proud of is the "Industrial Loft," which he launched in April.
"I'm quite pleased with the way it turned out. More so because of the fact that it's an open-spaced design, which means hardly any detail is hidden behind a wall. Everything is near visible from a single viewpoint," he said.
True to his username, the loft is a highly detailed large, open-air and modern multi-room set situated on the top floor of a high-rise building.
"I like doing interiors because they are completely standalone when it comes to lighting and rendering but cars challenge my building ability due to their complex designs," he said.
But that doesn't mean he sticks to just those images. He has also created props, clothes and other assets.
He finds inspiration in the world around him, which he transforms into his 3D and 2D art.
"This is actually a big problem because I tend to collect a lot of references, which are scattered all over my hard drive: photos, magazine shots, newspaper clippings, online image browsing," he said, adding he'll never get around to using most of it.
"But won't delete because I always think 'one day I could use this,'" he said.
TruForm's passion for art can be seen in all his hobbies.
"And if I'm not doing 2D or 3D then I'm dabbling in digital music creation. So obviously when my power cuts out then I only do human outdoor activities, like walking," he said, jokingly.
