Hi,
In this scene , the fur sop said: “The two sources have unmatched geometry”.
I don't understand the reason. Any help?

Thanks.

The Fur SOP looks for a primitive attribute called “guideorigin” on the guide curves that specifies where each guide hair attaches to the skin geometry in its rest pose. If the Fur SOP does not find that attribute, it assumes you want to use an old mode where guide hair ‘i’ should be attached to point ‘i’ in the skin geometry. The Fur SOP is complaining because it only found 6 guide hairs but there are 100 points in the skin geometry.

Attached is an example of how to create a “guideorigin” attribute.

You will also notice the Fur SOP interpolates the shape of nearby (see the “Guide Radius” parameter) guide hairs but does not affect where hairs are grown from.

Thanks derrick!
