Extract Alembic Data from file with API Jan. 25, 2021, 11:29 a.m.

Hey Guys,

Hope everyone is good !

I'm trying to use the houdini Alembic API. I want to extract point Positions directly with API and store them into detail attribute. I just need the positions for mathematical operations and as I'll have to deal with dozens and possibly hundreds of shapes with high resolution, I want to avoid slowing down the viewport so drastically.

I'm trying to use this code but I can't find the right name for position attribute anywhere.

If someone has an idea I'll appreciate greatly !

Thanks !

import _alembic_hom_extensions as abc
filePath = '/path/to/alembic.abc'
objectPath = '/hierarchy/to/myMeshShape'
positions = abc.alembicArbGeometry(filePath, objectPath, 'P', 0)
# result : ([], False, 'unknown')

How to control paint fuel (shelf tool) Sept. 27, 2012, 7:29 p.m.

Ok. It was just a matter of what order to use to make stuff happening.
I should have think about that.

Thanks you very much anyway Mawi.

How to control paint fuel (shelf tool) Sept. 27, 2012, 1:19 p.m.

I'm trying to figure out how I can control the fuel source by painting it on the geometry source.

I followed the documentation step but the tool just put a attrCreateNode (fuel) and the paint node after the OUT_SOURCE which is used into the Dop network.

I guess it's a really simple manipulation, but I don't get it.

I tried to put the attribCreate and the paint node right After the geometry source. but even that doesn't work. I tried to put the paint node into the pyro solver initial data but it's not working either.


Does anyone have any clue to light me up ?


Thanks

Pierre
