michaelb-01 Posted March 30, 2015 Share Posted March 30, 2015 I'm exporting some particles from Houdini via alembic (importing via exocortex crate), but how do I control the size of the particles when rendered (rendering in Arnold)? I tried setting pscale and radiusPP (on points and verts) in Houdini but nothing seems to work. And thinking about it I guess I would need to get opacity per particle exported too.. Or I could re-map these based on age in Maya.. Has anyone done this before? Quote Link to comment Share on other sites More sharing options...
georgeivan Posted August 24, 2015 Share Posted August 24, 2015 I don't think crate import any attribute at all,i just it a wall with this ,its amazing but looks like there is no way to export using alembic,the default importer in maya can import some attributes but its a joke it cant import particles,and looks like most of the studios are using custom solutions. So we are in 2015, and still we cant get particles going from A to B without custom solutions or the freaking Houdini engine just for particles.

StephaneS Posted February 14, 2018 Share Posted February 14, 2018 Hello, now we are in 2018, anyone gets a solution for this problem please ? Quote Link to comment Share on other sites More sharing options...
Jesus Nieto Posted February 15, 2018 Share Posted February 15, 2018 First, remember that maya scale is 100 times bigger than houdini scale, so whatever you are going to export you have to scale by 100. After that you have to multiply your "pscale" attribute by 100 too because it doesn't scale by default as "v" would. Then you would have to map it to the variable you need in maya, have you tried using "scalePP" instead of "radiousPP"?. Exporting Alembic should do just fine.

Mirrage Posted February 15, 2018 Share Posted February 15, 2018 What about adding correct attribute on the partifles in Houdini and then export to ASS? https://support.solidangle.com/display/AFHUG/Particles Quote Link to comment Share on other sites More sharing options...
plazadelmar Posted January 29, 2020 Share Posted January 29, 2020 Its 2020, did someone figure out how to render out pscale with alembic? Quote Link to comment Share on other sites More sharing options...
