I am trying to connect a Particle source SOP(_point3_RECEIVER_01.SOP) to an animated SOP (animated by Digital Asset custom panel), but it says an error message below. Please advise why it cause a problem or any solutions if you know.
“Warning: A mis-match of attributes on the inputs was detected. Some attribute values may not be initialized to expected values”
Ignore it. This is not an Error but Warning. It is caused by the fact that you merge two geometries with a different sets of attributes, so Houdini has to initialise some attributes in unpopulated parts.
If attributes exist in geometry they have to be present on *all entities of its kind (points, vertices, polygon etc). If you merge particles that posses velocity attribute with a static grid, Houdini will have to add velocity attribute to a grid (probably of value 0).
The problem is that it is possible that attribute's values initialised by Houdini won't fit your expectations. That is way the above Warning.
