Features

  • Collada importing from Blender via custom python export script (triggers Blender's collada loader + some addons for lights and physics) supporting:
    • Mesh, lights, rigid body physics
    • Mesh movement and skeletal animation
    • Light movement animation
    • Diffuse, normal, specular, parallax, displacement mapping. Textures are imported as bindless GL textures
  • Bullet Physics integration for rigid bodies (BulletSharp)
  • Deferred Rendering pipeline
  • Spot, point and directional soft shadows with variable penumbra (VSM + mipmaps + pcss style stuff)
  • HDR with adaptive exposure
  • Lens effects like bloom and lens flare
  • Depth of Field with Bokeh
  • Camera and object motion blur
  • Precomputed Atmospheric Scattering
  • Voxel based global illumination
  • Render modules system
  • Components system
  • ..and maybe some other things, I don't know :)

Controls:

Keyboard:

  • WASD / CTRL / Space = Movement
  • F = Flashlight
  • Z = Reel in picked object
  • X = Throw picked object
  • R = Reset Scene

Toggles

  • Tab = No Clip
  • CAPS = Mouse Lock

Mouse

  • Left Click = Pick / move physical object / Move camera when mouse unlocked
  • Right Click = Zoom camera / Poke the Goat!
  • MIddle Click = Take Screenshot

Exporting for Kaillash in Blender

Notes

Blender meshes must have the following to work with Kailash:

  • UV Mapping / Texture Coordinates
  • At least 1 material

If you are starting from a fresh blend, make sure to set all paths to relative: File > External Data > Make all paths relative

Exporting

  1. Create your scene
  2. Save the blend in KailashEngine2/KailashEngine/Resources/Blender/ (important for relative paths)
  3. Open up a Text Editor panel
  4. Open the file KailashEngine2/KailashEngine/Resources/Blender/Scripts/export_collada.py
  5. Hover the mouse over the Text Editor panel and hit Alt + P (this will run the script)

The script will create 3 files in KailashEngine2/KailashEngine/Resources/Scene/<blend_file_name>/

Workarounds

Blender's Collada exporter misses a lot of things. Below are some workarounds I've used to get things to export

Textures

Set the following texture influences for effect in Kailash

  • Parallax Mapping: Diffuse > Intensity
  • Displacement Mapping: Shading > Ambient

Running Scene in Kailash

  1. Put the blend's filename (without extension) in KailashEngine.Client.Scene Method: load
  2. Recompile and Run
