Realflow - single frame rendering, animation - not

[ragnakim]

Hi everyone,

I searched the forum first, and found nothing regarding this problem I found. So I hope I'm not reposting a talked about bug.

I was trying to render, in 3ds max 2014, a liquid simulation using geometry made with Realflow. Basically using the realflow loader plugin. And the problem I found, is that in a still frame it renders perfectly. And you move the time slider and render another frame, and again it renders perfectly. The bug is when you render a sequence. Everything is animated correctly camera, objects, etc. Expect the real flow liquid. Its always stuck in the first frame. I've tried several thing and none worked. Even rendering with 3ds max command line.

The only way I was able to render the animation with the realflow simulation animating correctly, was using 3ds max's Batch Render, and painstakingly creating a "pass" for each frame.

Does anyone as the same problem?

Cheers

p.s.

Pardon my bad English :P

The same happens here... yesterday i try to render some hybrido meshes (bin mesh secuence generated from realflow) and the animation works for a single selected frame but not in animation render mode (just keep rendering the las selected frame in viewport).

Not a problem at all with particle emitters, just Hybrido related it seems.

exactly. Its a strange bug. because you can choose any frame to render. and it renders correctly. I could only solve this temporarily by script. :-\

A script?... where? ...  i'm facing the same situation on realflow and phoenix.

I'll try to find the script and post it here.

i'm also facing this problem with realflow meshes and hope you can find the script and share it whith us.

its not corona bug , its realflow plugin bug

its not corona bug , its realflow plugin bug

thank you!

While we have you here, what's the executive summary to supporting realflow in 3rd party renderers? Do you have some specific API we can get access to? Do you provide NFR licences for development/debugging?

Hi All,

I've attached the script I wrote to get around this problem. It'll render whatever's in your "Range" parameters in the Render Setup window - not what's in your Active Time Segment. It'll work with render elements too, renaming the outputs of both those and the main render output to respect the frame you're on.

Any questions, please email dbg@riverfilm.com. It's all commented so it should be easy to work out what's going on if you'd like to look or edit it.

@DanGrover: A little tip: you can make the digits thing a lot easier (and extendable) by using formattedprint:

Code: [Select]

formattedprint 1 format:".2d"  -- prints "01"
formattedprint 1 format:".3d"  -- prints "001"

No s**t! I had no idea - thanks man!

Just to note, this is a problem with Phoenix FD liquid sims too.
The exact same behavior...render any single frame, no problem. Render a sequence...locked to the current frame.

script fixes the issue
not Corona-related
