exporting voronoi fracture to Maya

[ollynash]

Hi,
 

I'm shattering some geometry in Houdini and applying Rigid Body Dynamics and need to get it back into Maya for rendering.  I can successfully create an alembic of the packed geo (there are hundreds of pieces) but it's a large file and renders really slowly in MtoA.
 

I figured exporting an .ass archive from Houdini would be lighter and quicker, but I can't get it to work on this shattered geo....the resulting file size is 300Kb and when loaded into Maya the standin cube remains at globafracturingl zero and doesnt' change size (yes I have switched to Legacy Viewport)
 

I check ON Binary Encoding and Export Shaders in the Arnold Archive option and uncheck everything else.  I'm fairly new to houdini so think there must be something else I need to do after DopImport in my rbd sim.
 

Anyone got any tips for success please?

Cheers,

 Olly : )

If you are using packed primitives.  Use the rbd to FBX exporter found in the game tools.

I'd rather not use FBX, not very efficient.  I have found that checking "expand procedurals" in the Arnold Archive options generates files that are  of a reasonable file size (14Mb per frame) and is more what I would expect.  The standin changes size in Maya which indicates its reading the geo ok but it still doesn't render, just black frames : (

The size issue might be a centimeter to inches thing.   Try adjusting your scene measurements.
