most nodes, will crash if you reload a file on top of a current file with partio nodes.
I'm not sure if this is caused by the partio library or maya issues yet.

Partview crashes currently when loading particles with color and trying to turn the color channel on and off and also advancing the frame too fast on a heavy cache will cause segfaults

Latest version of vizualizer seems to export 'renderCachePath' wrong. It looks sort of this:

"C:/temp/partio2/dropsShape.0094.bgeo. < frame > .bgeo"

Make the partio Exporter gui store the status of the checkboxes on a particle system so that every time you go to export, you don't have to recheck the attrs one by one.
store the data on the particle object itself so that it carries along with the node.

need to create a full shelf mel file for the release to support all the features of the new nodes, especially
the partioInstancer connection

PartioInstancer is functional , but the code could use some cleanup
do that...

It should take the current maya frame rate to compute the timecode.

would be cool to have a "by frame" skip retimer for cache loading

I've tried this with Maya 2014 in Mac OS X and Linux, and they both do the something...
I really need a solution to load Houdini Particles into Maya, but nothing is working...

For motion blur effects, it may sometimes be nice to be able to swap out the velocity channel for another channel or have multiple velo channels for different passes all in one cache.

Add a "velocityFrom" pulldown to the instancer and visualizer nodes, emitter already
has the ability to map position and velocity.

Hello,
I hope I'm posting this at the right spot.
I've been trying to get partio4maya to run on at least 30 different systems so far.
Most of the machines use win vista 64 ultimate ..some use win 7 pro
I really can't figure out under what conditions the plugin is running or not ..the computers
have all the latest updates installed. I got it working on 8 machines. On most computers
it won't run. The error messages seem to be related to the zlib.dll "the module could not be loaded blabla..."
I'm not a programmer ..and unfortunately have no idea of how everything works (c++ compiling etc.)... but here is my question:

Obviously the zlib.dll is the only thing that needs to be installed separately ..would it be a big thing to just include
the necessary parts of the lib into the plugin.. to make sure it really runs on every system?

Or second question: I'm mostly using the RIB export so far ..for most other problems I also got other solutions..
Is it possible to get a RIB only version from you ...or maybe some limited version that won't need the zlib.dll? (guess its just needed for binary files!?...is it?)

That would make life for me so much easier for my experiments with the render farm I've got access to. Just installing the zlib.dll
on all computers by hand takes half a day ..compared to just dump the plugin on the server to the pluginpath of maya.

thanks for your time

please some way to add 3delight pointcloud format for read???? Thanks.

Hi there,

I mentioned this once before with not much of a resolution.

Now that PfTrack can export coloured XYZ files. I tried import one into Maya using PartIO by:

• adding a Viz node
• importing the XYZ file from PfTtrak
• nothing happens

It really does appear that the OSX version of PartIO just doesn't work.
Is there anyone out there on OSX that has had some success?

Please don't ask for a white paper on the format used by The Pixel Farm as with PhotoScan I have no idea what they are doing or which white paper they based the their version of the format on. To me they look the same and any other.

Is there anything I can do to get this working?

Thank you.

When two emitters are in a same scene, opening a new scene containing another partio emitter will crash maya. (Seg Fault).

I've pinned down the problem : it's related to the callbacks, and more specifically this line :

MObject tmo = thisMObject();

But I have no clue why exactly yet.

Implement a new maya node that implements a "loader" and outputs to mesh type. This will be the gateway to deforming partio caches. etc...

When setting cacheActive = 0, and selecting a new cache file, "renderCachePath" attribute is not updated.
This is confusing, since I disable "cacheActive" to speedup viewport, but I'd still like to get valid "renderCachePath" for my procedural.

Support pulldown for radius, radius multiplier, and open gl draw of radius points using billboard draw method.

Need to fix the "reset" memory leak in the visualizer and instancer.

create a command that creates a particle object and populates it with the argument frame's particle data.

opacity issues cause incorrect overlay of OGL points on top of background color instead of image plane data.
try to figure out how to fix this.

It appears that when particles die currently in the partio emitter node, that its doing soemthing that ends up killing every particle per frame and re-populating with new ones.. this should not be happening, it should only add/remove based on partioID and move the other particles accordingly.

look into this..

We need to create a single unified place in partio for particle expansion to use by render side procedurals. This will allow for renders to match particle positions across different renderers implementations of expansion.

A very big cache could be for instance a 4Gb/frame.

On our workstations each loading when scrubing can take in this case 45 sec when scrubbing the timeline which is quite problematic in term of interactivity for the users.

Here is a hack, yet fonctionnal, to skip a certain percentage of .bhclassic particle from loading.

https://github.com/mikrosimage/partio/tree/mikros
commit [Partio4Maya] add a skip load feature (WIP: very ugly hack on lib/io … (11c4e73)

right now the file name code is replicated across all the nodes,
I need to bring them all together into one shared function set.

additionally I need to make static cache work for any file format in a more intelligent and rational way.

Implement code to do things like:
merge / remove points that lie too close to one another
remove outliers beyond certain thresholds
remove outliers based on attr input range
Implement bounding box culling/keeping
probably more to come....

It would be usefull if partioExport had a flag overriding filename.
Right now filename is a particleShape.

This is handy when batch-baking several passes of simulation into Krakatoa-like namig scheme:
SmokeShape__part1of20.#.prt
SmokeShape__part2of20.#.prt
...

need to wrap the partioExport to allow escape interruption

Add file format support for pointCloudLibrary PCD file format.
pointclouds.org

in the 0.9.3b release the partioEmitter does not function correctly and emit any particles unless it is able to read a velocity channel which is not always available, from the cache file.

maya 2015's viewport defaults to using viewport 2.0 now.
and it has many improvements for displaying large particle clouds
take advantage of this and support it.

I need to unify the file browser code for all nodes to one common library.
right now its splintered

When you reload a scene file with attr mappings setup for a partio emitter
the attr mappings are initialized and cleared out instead of inheriting what is in the file.

Add file format support for point cloud PLY file format.

implement a crop box input to the partio4 Maya tools this may end up being better to put into the core partio code, but I'd like to support arbitrary oriented box or sphere
and have it support crop at load time, or crop at display time.

Hi,

I'm trying to load/read a Nparticle cache with Partio Visualizer but when I select the file in the list maya crash.

I'm using Maya 2012 x64 sp2 on win 7.

This is the filename: nParticleShape1Frame200.mc.

Hey guys,
Bgeo from houdini 12 and up doesnt work, because sidefx switched their bgeo's to binary json format.

Partio4Arnold procedural only supports 4 padded frame numbers.
make it support any arbitrary padding and also support "filename_#.ext"
as wel as "filename.#.ext"
