The realistic animated model in the scene is ready to render (look at first Preview). It is made in 3ds Max 2014 with Vray 3.2. You can see Video Preview in additional Files. The duration is 300 frames during which bubbles are swirling in the vortex and rising up, foam is growing up as well.

There are Geometries, Particle Flows (cached in file max), Vraydisplacementmod, Lights, Space Warps, Vraymaterials and no Bitmap Textures. Procedure textures have been included and animated so it is important to consider Unit Setup (look at Preview).

Worls units - Centimeters, System units - Inches.
Size of Glass - 20x9x9 cm.

Materials and geometries have been named properly so you can find easy any one. Including you can change color of foam in map "Color_of_Foam" of material "Foam_Inside" and color of Cola in material "Cola". Also you can change parameters of Bubbles ( Count, Size, etc.). Just enter Particle View, change whatever you want and update Cache operator.

Whole content of scene is included into certain Layer "Cola". You can see Render Setup at Preview.

Notice that VrayLight003 has set of include objects of scene.

If you wanna reduce time of render or you have some wrong artefacts in reflection of the Glass or Cola you can remove the tick "Reflect on back side" in materials.
