We did some studies, how we can achieve a new kawoosh effect for the gate. After watching a lot of behind the scenes and making of clips of Stargate, we came to the conclusion that we have to make a kawoosh like the VFX specialists from Stargate themselves.
Unfortunately, we can’t film underwater explosions and use video footage of it in a 3d game. Therefore, we need a 3D underwater explosion, which is simulated and somehow inverted.
So here is the result of our first attempt.
The first kawoosh is only consisting of Sprite particles like in old half Life 2 mods.
The second kawoosh is made like every other Fan Made Kawoosh effect by using displacement Maps and a hand animated 3d model using blendshapes.
The third Kawoosh is the result of our first liquid simulation attempt.
Shaders of kawoosh itself and the Gate puddle are just placeholders, but we finally found a workflow to simulate a real kawoosh... :) the shaders have to be improved to look more like bubbly water and
