Is there a limit on the number of simulations per scene ? Plus I have a 'copy' simulation issue.

[JezUK]

I have a scene to produce an animation for - a ship in the sea, and this ship (a cruiser) has around 25 jacuzzis and 2 swimming pools with cascading waterfalls.

That to my mind is;

1 x sea simulation,
25 x jacuzzi simulations,
2 x cascading waterfalls into swimming pool simulations.

The animation is going to be around 30 seconds long.

My first question is - is it possible to have all of the above simulations all contained in one scene so that when the frames are rendered all the simulations will work correctly ? (I'm concerned that I was told it could but my findings tell me something else).

My second question relates to the first - in a previous thread on here, I was told that copying the simulation for my jacuzzis was no problem. But I am finding it *is* a problem, basically so far for me it doesn't work.

Please can Chaos confirm that for a single scene, it is indeed possible to create one jacuzzi simulation and then copy this simulation to many other jacuzzis located in different places on my ship but all within the same scene and that when rendered, these should all work as expected (i.e. correctly) ?

When I have tried it, the simulation preview for my jacuzzis in my 3ds Max viewport all 'look' the same (as though they've worked), but when I render some frames out, the copied ones lack bubbles / splash / foam (even though the preview in the 3ds Max viewport shows there to be foam/splash/mist etc for those jacuzzis which had had copied simulations). The original (first) jacuzzi simulation however looks fine in both preview and in renders.

Please can someone advise/confirm ?

Many thanks.

Hey,

Yes, many simulation copies will definitely work.

Currently, the Phoenix Simulator loads cache files, and can show preview for all the data loaded - both and grid, particles, and can also render meshes and volumes based on the grid data.

Particles are not rendered by the Phoenix Simulator. There is a Particle Shader that does that. You can either select the particles from the copied simulators in the Particle Shaders that rendered the original foam, splash and mist, but if you need the Liquid Simulator slot of the Particle Shader (check the docs for more info), then it would be a better ideas to copy the Particle Shaders too and link each shader with its respective simulator. If you don't need the Liquid Simulator to be set for the Particle Shaders, then you can pick all particles in their respective shaders and use just the original shaders.

Hope this helps!

Hi Svetlin,

I should have spotted that, but I was too tired - my bad.

However, whilst I understand everything, it is still not working.

I have a habit of renaming simulators and their Particle shaders etc, and I think this might be messing things up such that what I want to do doesn't work - for example, when I rename a simulator, the previous names are stored some place such that when I then try to add the PG [Foam] for that simulator into the shader setup, the old simulation name is there..... and when you have 25 jacuzzis to deal with, this will break things.....

I will try from scratch once more and not rename anything (to see if that is actually the issue here).....

Many thanks.

Hi Svetlin,

I managed to get this working - but I do believe it was an issue with renaming simulators after they'd had Foam / Splash enabled (and shaders had been created for them).
