Houdini Procedural Generation


Houdini Afghan Desert


Houdini Snowy Mountains


More demos to be described soon-ish. You can look forward for procedural building placement for villages/cities and generating road network with crossroads. Current work is under NDA, so I have to make new demos :).



Technical Art


Rendering Engine in Python and OpenGL

To learn more about shaders and game engines in general, I've spent about a year of my spare time developing a rendering/game engine in Python and OpenGL. The journey took a long time, but I've managed to write Forward and Deferred Renderer supporting old diffuse-normal-spec workflow, extended reflections and full PBR rendering model. All of the shading models are switchable in real-time. Most of the important features like shadow mapping, improved SSAO, tone mapping, FXAA and Natural Bloom were implemented too.


Optical Flowmap Distortion Generator
Optical Distortion Flowmap Generator is a tool I wrote back in March 2017 as a part of an texture atlas tool I needed for VFX. It's written in Python and PyQt5. For more information you can check this page.


Substance Designer Materials
Here you can find some of the Substance Designer materials I've created in the past. All of them are of course full PBR and with some little effort several variations of the textures can be made.





Realtime VFX

Here you can find some of the Realtime VFX I've been working on lately. The content on the page is WIP regarding to dependency on other assets and in most cases on work of other people.
