underwater explosion foam issue

[stevesideas]

Foam seems to be getting stuck in the air. Pretty much default values.

the foam falling speed is too low, increase it.

[stevesideas]

Is there a way to calculate the foam only once the base simulation is calculated. I don't want to keep having to calc the base sim as it takes quite a bit of time.

[Ivaylo Katev]

yes, there is an option to resimulate the foam, see the resimulation panel. disable the grid resimulation, enable the particle resimulation.

[stevesideas]

ok thanks.

[stevesideas]

Sorry, one last question. Is there a way to offset the entire grid, foam and splash simulation so I can add a bit more lead time to the sequence ?

[Ivaylo Katev]

yes, in the input panel you have a parameter that can introduce offset in the sequence

[stevesideas]

Great.

I've got another problem now. Since adding a PHXFoam helper to shade the foam I'm getting the attached error.

[Ivaylo Katev]

another user reported for problems with irradiance map, is it involved here?

[stevesideas]

I'm using BF+LC & Vraysun system.

[Ivaylo Katev]

can you attach the scene with a single cache that porduces the bug? you can send them to the support, if the cache is too big.

[stevesideas]

Here you go. Thanks.

yes, in the input panel you have a parameter that can introduce offset in the sequence

So, I've adjusted the cache start and play start (I don't understand the difference in what they do) and they both seem to work but if I change the start time so I have more lead time to the sequence the ocean displacement does not animate in the viewport. Can I assume it won't animate at render time also. If so will I have to resimulate everything with the lead time built in ?

[Ivaylo Katev]

it will animate in rendertime, don't worry (but still test it). the lack of animation of the viewport is because there is no change in the cache (the first one is used) and the mesh is not updated.

[stevesideas]

Okay. good to know.
