Problem with molotow-cocktail - liquid through wall

nevertheless we have to find the reason for this behavior

Second that. Shall I give you the scene?

[Ivaylo Katev]

first we will try to reproduce it

Ivaylo!

Were you able to reproduce this behavior?

[Ivaylo Katev]

not yet, but we didn't try it, just scheduled.

Yeah, okay, if I have problems with that issue, I will report them. I have to do several more playspeed-animations due to a bullet-time-shot with 4 simulators...

[Sascha Selent]

Ivaylo!

An idea: wouldn´t it be great to have some proxy-functionality? My scene has now several sims with multi-million cells - an animating the scene is a real pain! If there was a possibility to use proxy-sims just for the viewport-display - with waaay downscaled resolution for the grid - that would be incredible!

It might be even possible to take the high-res-simulation to generate a low-res-version from that. So you have to simulate only once.

In the output-module there could be a "Generate proxy" option with half/third/quater/eighth settings - generating a similar named output with "proxy_half" suffix or something...

...and in the input there might be the usual proxy-functionality - "Use proxy" - "Choose proxy" - "use for rendering", etc.

What do you think?

yes, this feature is already discussed, and it will be implemented. of course not a different file, just a small copy in the same file.

Cool.

But doesn´t that mean that the whole file has to be loaded? With a sim with 80MB per frame - nearly 2Gigs/s @ 24fps the - HDD is the bottleneck - LAN is much worse. With several simulators of that size it gets horrible...

[Ivaylo Katev]

yes, the main idea is to skip the loading, because it is slow for large sims, even if no further processing is carried out

So only a fragment of the *.aur-file has to be loaded?

[Ivaylo Katev]

yes, this is technically no problem. now even if you have reduced preview, it loads and uncompresses the entire data, that is slow.

Problem with Anim Index

Ivaylo!

Aaaargh, so here I have the problem with changing the playspeed again! Remember?

Here is a preview of my scene:

You see that there are jerks and jumps in the sim.

I animated the Anim Index - but at the moment it does no changes -I have a stright line from -100/-100 to 2000/2000 - what means that I do not have any timechange at the moment - but the jerks happen...

This makes my blood freeze - I have to deliver end of february!

Heeeeelp.....

[Sascha Selent]

I hoped that it would not happen on render, but here is the renderresult:

It´s even worse! The anim is really jerky!

AAAARGH!

What do you think could be the problem?

• I have sims starting at -100
• I have multiple sims with different sim-start-stopframes (I just deleted all except one - no changes)
• I set the playspeed to 0 and use only the anim index (tried this, doesn´t change)
• I also reduced the simulation-speed (not playspeed)
• Max 2012

Wow, I really need a solution for this or I really get in trouble!

Do you have any ideas for fixing / workaround?

I´ll try to reproduce it with a simple scene...

Thank you Ivaylo!

[Sascha Selent]

Doesn´t the Anim Index use blending? Only the Play speed?

I cannot reproduce. Could it be that these may be frames where I paused the sim to testrender or to render a preview? Or maybe restoring? I did this several times, especially when max crahsed....
