Can anyone tell me why Houdini and Maya can see each other's vertex colours, but Blender's aren't visible in Houdini or Maya? Looking at the logs here, is it just as simple as adding a mayaColorSet=1 flag to the Blender compound property on export? Here's how vertex colours are represented in each of the Alembic exports. crv_GP_Layer_1_mesh_007/crv_GP_Layer_1_mesh_007Shape/.arbGeomParams: Houdini Apprentice is a free version of Houdini FX which can be used by students, artists and hobbyists to create personal non-commercial projects. Can anyone tell me why Houdini and Maya can see each other's vertex colours, but Blender's aren't visible in Houdini or Maya? Looking at the logs here, is it just as simple as adding a mayaColorSet=1 flag to the Blender compound property on export? Maya: Would love to know if anyone sees something in the way the Cd attributes are structured that could provide a clue. Then I ran the output of each through abcls and added the logs to the attachment below. * Blender can see the Cd attributes on all three files (although the Maya vertex colour order is wrong-a known issue that doesn't happen to affect my pipeline). * Maya sees the Blender Cd attributes but they contain no colour data. * Houdini doesn't see the Blender Cd attributes at all. * Maya and Houdini were able to read each other's vertex colours, but not Blender's. Blender can see the Cd attributes on all three files (although the Maya vertex colour order is wrong-a known issue that doesn't happen to affect my pipeline).Maya sees the Blender Cd attributes but they contain no colour data.Houdini doesn't see the Blender Cd attributes at all.With Houdini Indie, users can export their models and scenes in the Alembic format, making them available to other 3D programs such as Maya, Unity, Blender, Cinema 4D, and 3ds Max. Alembic is a file format used in 3D computer graphics software to store and exchange animated 3D models and scenes. Maya and Houdini were able to read each other's vertex colours, but not Blender's. Yes, you can export Alembic Houdini Indie files. ![]() (In Blender I applied vertex colours with the common Python function below, just in case that's helpful to know.) The results: To make the attached test, I took the same mesh into Blender, Maya, and Houdini, and exported an Alembic file with vertex colours from each the attributes are all named Cd to match Houdini convention.
