General CG Discussion / Re: Phoenix wave splash against wall (huge scale)

*just to ping you*

Georgi, is there a way to increase sub sampling of an plane with the oceantex map as vector displacement in Corona? In phoenix sim, you can do it under the rendering tab, but for one of my shots, I have to use just a normal plane and I'm getting some "glitches" in the ocean with suddenly a long wave appearing for 1 frame and then it goes away again. Happens every now and again. So I'm thinking it might be due to some setting in the oceantex as rest of animation is fine.

Sounds like a bug but I can't reproduce it on our side. There are no specific settings for this I'm afraid. Is this on the same machine that we suspected of having issues with the memory?
Is it possible to send over the scene?

Thanks!

I have simulated 600frames and I'm at 300gigs now, I probably only need the last 300-400frames, so I tried to remove frame cache 1-199 from the sim folder so I wouldn't have to upload it all to the farm, but if I do that, max crashes on render start. Should I or can I do it differently?

Can you give me a bit more details on the rendering part? - it should be working without issues.

Are you rendering with Corona, if yes which version? Are you rendering a sequence, are you starting from a frame where there is no cache, is there motion blur enabled?

I'm afraid that matching the waves in the simulator to the displacement outside is still not possible. It is in our to do list though, so will add your vote for it as well.

As for the different materials - what should happen at the border of the simulator, how would the two shaders blend?

Can't say for sure what happened. It might be due to the the faulty memory or it might be Windows. You can check a few tips on the testing from the thread in our Phoenix facebook group here - https://www.facebook.com/groups/233735903483447/permalink/1565999250257099

As for V-Ray - you don't need it in order to simulate with Phoenix. Phoenix would still be able to simulate, load, save and preview caches, and it would render with the Scanline Renderer or Corona.

I hope this helps!

Thanks a lot for the help, unfortunately we can't reproduce the crash on our side and the dump shows that the crash is somewhere outside the phoenix code.

It might be a hardware issue (a few of our users have reported crashes that turned out to be faulty RAM). If possible can you run a memory test on your machine so we can rule this out?

Thanks a lot for the video!

Can you also tell me the exact Phoenix version and Build ID you're using - you can do that from the Top 3ds max PhoenixFD menu > About Phoenix

Also can you send over the Phoenix log, please grab the Phoenix log immediately after the crash. If you start 3ds Max again, it would be overwritten. You can find the log in C:\ChaosPhoenix

Thanks!

Subscribing to thread. Every time I trialed Phoenix I realized I am dumb and it never worked how I wanted. Plus crashes, yes.

haha yes, the tutorials mostly looks pretty straight forward, but when I try and copy them step by step, results are not the same at all and trying to find out the correlation between settings is crazy. At least when you are working with a deadline. Also the sample scenes on their site doesn't work out of the box when I try them out. Maybe it's a corona thing too...

The example scenes on the docs were setup with V-Ray, but it should be possible to make them work with Corona as well. We'll try to make Corona versions for the files, but until then - ping us if you find anything you need help with.

As for the tutorials - if you feel some of the tutorials on our page are not explained well or produce vastly different result, let us know which one is it and we'll investigate.

Thanks!

It should definitely not crash. Can you get us a scene that is crashing or if it is not scene specific what are the steps to crash it?

Phoenix 4.00 was released in almost 1 year and a half, since then we introduced a lot of fixes and improvements. The latest official version is 4.30. This should work with the render farms as well.
You can find what changed in each version here - https://docs.chaosgroup.com/display/PHX4MAX/Version+Change+Logs

As for the strange liquid interaction - make sure that your geometry is clean (no overlapping faces, no single face geometry, no open edgec, etc), otherwise the simulation might not look good.
If you're using Include list - you will need to put everything in the list (sources, forces and all the geometry you need to interact with the sim).

Hey,

There should be no issue to make one large simulator around the island.

If you can't make it larger, probably the size sliders got maxed out. Just increase the cell size (or use the decrease resolution button) - this way you should be able to increase the grid size.

When doing such simulations scene scale is really important. Even if you scene is not built up to the real scale - you can change how the simulation behaves with the Scene scale option in the grid rollout of the simulator. You can find more about it here - https://docs.chaosgroup.com/display/PHX4MAX/Liquid+Grid

For the large waves you can take a look at this tutorial here -

As for the X-Refs there should be nothing special - it should work out of the box.

Cheers!
