Maya Fluids
Beta version - will be updated
With some special effects FurryBall supports there is the need to let the user change and tune some custom parameters. Fluid Node is another settings node in FurryBall, it is connected directly to a fluidShape and adds several new attributes.
To be able to use attributes described below a fluid node has to be attached to a fluid you want to adjust settings for. To attach fluid node to a fluid, just select the fluid(s) and select 'Add Fluid Attributes' from the main FurryBall menu. There is always a 'New' menu item and a list of existing fluid nodes in the submenu, so you can create and attach a new fluid node or attach an existing one that is already used elsewhere. See User Interface section for more details on other settings nodes.
Set the number of samples.
NOTE: Those samples are defined per Maya unit not per voxel. It is very useful. You can even set less than 1 sample per voxel to accelerate rendering (great for tuning scenes)
Use to fine tune fluid noise or remove visible repetitive pattern.
Fine tweak edge drop-off with distance from fluid center. Use this create complex drop-off patterns.
Settings of depth map shadows for fluids. The PCF shadow blurring works in fluids. But it is slow. So we added some possibility how to speed it up. You probably don't need to filter shadows in fluids at all. But when you need to: you can use less samples and having feasible results.
Enables or disables self shadowing on fluid.
Multiplies number of samples defined in FurryBall Light Node.
Defines how much are non-illuminated areas of fluid transparent. This feature enables you to create "light shafts" effect very easily.
Can be used for having more physically correct results of fluid renderers. Phase Function can be used for approximating light scattering in clouds or smoke. Evaluation of phase function doesn't affect rendering performance.
When checked, phase function is used for rendering
Sets the intensity of phase function
Offsets the phase function value
Fluid from the back (Left without phase function, Right with).
Phase function has maximum effect on the side against the light
