26 : Attack on Killa
3 minutes read
Killa scene
The first two shots were recorded in-game on Interchange with the Freecam mod. The third shot is a Blender scene with a motion tracked background.
Scene setup
I thought the motion tracking would be easy, since there is a flat floor with well-contrasted, sharp patterns. For some reason it was a pain, I could never get an accurate track. I don’t even remember how I made it work. It seems I deleted most of the tracking points on the floor and used exclusively those in the background. I ended up with a barely acceptable 1.01px solve error.

For this scene, the grenade is parented to the camera and only rotates around its own origin.
Screenshots of the in-game location were imported as emissive meshes in order to provide more accurate lighting.
Killa’s rig and armor were not available in chriscya’s EFT multirig and have been imported separately. They are constrained by an armature modifier and custom weight painting with the relevant bones. It was not really a perfect solution, but it was sufficient for this scene.
Compositing
The action is stopped when the grenade arrives near Killa. The image takes a brown tint with a pattern looking similar to brosh strokes.

To make this effet, the image goes through Sun beams and Bloom effects to achieve a “dreamy” aspect. Then, the image is mixed with a sepia version of itself (this allows to control the sepia amount and keep a small amount of color). The “brush strokes” is a MP_Comp Voronoi noise texture, scaled on the X-axis to stretch the effect, and rotated by 30°. A color ramp controls the contrast of the effect. It is then multiplied with the sepia image.
Flag
I originally did not know what to do with this scene : in AoT, this is the scout regiment’s flag. But in Tarkov, there are two main factions and even though the “main protagonist” is a BEAR in this video, it did not feel right to ignore USEC.
Then I discovered that Tarkov actually has a in-game flag and coat of arms ! The latter is visible on police cars on Streets of Tarkov. This was the more “neutral” option I needed.

To make the flag, I edited the Tarkov City coat of arms onto the Tarkov city flag to get a more interesting look. Then, the image was imported into Blender as a mesh plane.
To animate the flag floating in the wind, I used the same method as in scenes 4 and 5. Refer to kutson blend’s tutorial for more details.
