Denis Dvorkovyy - Tech Artist

Absolutely in love with making graphical effects and tools that help make graphical effects. 

PROJECT

They are in the thousands

They are in the thousands is a small game I made to see how far I can go with making almost fully GPU sided. The terrain carving, physics, enemy ai and the weapon VFX all run on the GPU using a combination of compute shaders/ shadergraph/ vfx graph.

Exarion

Exarion is an alpha map creation tool to easily create highly versatile alpha maps. The tool has a drawing space and a timeline where you can manage your brush strokes. Below is a video showcasing how the tool works

Mesh traversing

A simple floodfill effect running on compute shaders using a pre baked buffer containing all the neighbouring triangle data. The effect uses custom structs in the vertex buffer so that I can read the data in shadergraph using uv nodes.

Triangle explosion

My first adventure with compute shaders without using tutorials. I thought it would be cool if every single triangle of a mesh has its own logic. In I made a sort of advanced displacement shader where you can move the mesh and the affected triangles won't move with it. I showcase this in the video below.

GPU Instancing and vertex position textures

I made a simple tool in unity that converts animations to textures by storing the vertex data in a texture using compute shaders. With those textures I can play animations very efficiently over many models.

UV Painting integrated with the VFX graph

This effect was made for a game where you needed to clean up the world. So I made this effect where blobs of oil would "taint" the objects and you could clean them up.

Shell texturing for fur/hair

I used shell texturing to create the fur effect. For the motion I compare each vertex's position to it's previous position to get the velocity. I then sample the velocity in the material shader to offset each hair strand.

Custom mesh Sci-Fi shield

I wanted to create nice looking Sci-Fi shields that work on any mesh. For this effect I created a small custom tool that clumps all neighbouring triangles together. I then use that information to display the clumped triangles in a nice way using a geometry shader and a compute shader.

Per object shadows

I noticed that shadows were always black even in highly stylized games. So I made a system where you can easily add customized per object shadows. For this to work I had implement my own lighting solution that works besides Unity's lighting system. This system was made with the new rendergraph API.

Mesh voxelization

When I was interning at Knucklehead Studios I was tasked with creating a kill effect for an arcade vr shooter. I created an effect where I pre-generate an SDF, store it in an append buffer, then pass it to the VFX Graph to use it to get the spawn positions of the voxels.
