3ds Max Fluids Foam always black

[Anonymous]

Hi there,

Per the image below I feel I have all the settings correct when using a standard Volume for rending foam in max, but it is always black.

I have underlined the various elements I understand I need for this to work, yet it is always black.

Does anything jump out as obvious as to what I am doing incorrect.

It's a problem with the bifrost_points object, and we have an open ticket for it.
You'll need to add an operator to set the step size. In this screenshot, I have a Set Parameter that sets the step_size (and I made the Set Parameter the target operator).

Still the same I am afraid, I am not sure what I am missing with this.

I would be surprised if the multi/sub-object worked with it tbh.

What happens when you just assign the standard_volume?

You have to set a target operator
