Hello,

Very much looking forward to Clarisse 3.0! Can I ask please, in the new version will it be possible to export scattered geometry to other software? I'm currently looking into the potential to 3D print objects originally created in Clarisse. Which would be awesome

Thanks,
Mark

Hello Mark,

We already have a confirmed feature request #2473 to be able to export in alembic combiners and scatterers geometry contents. We will keep you posted about how implementation goes.

Hello Halim,

Thanks for responding. That's good to know it's being looked into.

Thanks,
Mark

Hi Mark, the only issue is which software will be able to load the scattered result?

Maya ?

I just exported some scattered geo from Pegasus. It was a field of 5000 simple spheres, but it worked. I imported the spheres into Maya and that was pretty smooth as well. You have to be careful of the geo count though. First off, Clarisse is very good at handling high poly counts. Things that put Maya into the terminal ward at the hospital are like a walk in the park with Clarisse. On top of that, when you scatter in Clarisse you are making use of instancing. When you bake it into an exported geometry you are converting every single instance into a unique collection of polygons. That will get huge really really fast.

I assume you used the export Geometry, which bakes everything into an OBJ?

Any updates on export scattered Geo with the alembic function?
Basically it would be nice to be able and bake the scattered contents, even it does not make sense in a "pure" clarisse workflow.

Hello,

A new alembic exporter will be available in the next version of Clarisse, offering two ways of exporting scaterrers, bake or layout mode.
Until then, you can use this python script which will 'explode" a selected scatterer:

Code: Select all

if ix.selection.get_count() > 0:

    item = ix.selection[0]

    if item.get_module().get_class_info() != ix.api.ModuleSceneObjectTree.class_info():
        ix.log_warning("You must select a SceneObjectTree!")

    ctx = ix.create_context(item.get_full_name() + "_exploded")

    print ctx
    scene_object_tree = item.get_module()
    instances_id = scene_object_tree.get_instances()
    item_mx = scene_object_tree.get_global_matrix()
    for i in range(instances_id.get_count()):
        instance_id = scene_object_tree.get_instances()[i]
        instance = scene_object_tree.get_base_objects()[instance_id]
        final_matrix = ix.api.GMathMatrix4x4d(item_mx)
        final_matrix.multiply_left(scene_object_tree.get_instance_matrix(i))
        new_cpy = ctx.add_copy(instance.get_object())
        new_cpy.get_module().set_matrix(final_matrix, ix.api.ModuleSceneItem.SPACE_LOCAL)
else:
    ix.log_warning("You must select a SceneObjectTree!")


Kind regards

Here is an improved version which takes into account the matrix of the scatterer/combiner. However, it requires Clarisse 3.0 SP4 or higher to run.

Code: Select all

#checking minimum version requirements
version = "3.0.0.0.4" # 3.0 SP4
if ix.application.get_version() < version:
    ix.log_error("This script requires a newer version of Clarisse: " + version)


if ix.selection.get_count() > 0:

    item = ix.selection[0]

    if item.get_module().get_class_info() != ix.api.ModuleSceneObjectTree.class_info():
        ix.log_warning("You must select a SceneObjectTree!")

    ctx = ix.create_context(item.get_full_name() + "_exploded")

    print ctx
    scene_object_tree = item.get_module()
    instances_id = scene_object_tree.get_instances()
    item_mx = scene_object_tree.get_global_matrix().get_copy()

    for i in range(instances_id.get_count()):
        instance_id = scene_object_tree.get_instances()[i]
        instance = scene_object_tree.get_base_objects()[instance_id]
        final_matrix = ix.api.GMathMatrix4x4d()
        final_matrix.copy_from(item_mx)
        final_matrix.multiply_right(scene_object_tree.get_instance_matrix(i))
        new_cpy = ctx.add_copy(instance.get_object())
        new_cpy.get_module().set_matrix(final_matrix, ix.api.ModuleSceneItem.SPACE_LOCAL)
else:
    ix.log_warning("You must select a SceneObjectTree!")

Awesome! Thank you for providing the script. I just tried the first script, and seems to work great. I will keep testing
