I created a large grass field in Sops with fur. But I can’t import this in Houdini (I het spheres). How can I fix this? Or is there a better way to create a large grass field in Solaris?

The most common problem I see when importing curves from SOPs is when there is no width attribute set on the curves. In that case, USD (and the renderer) use the USD default curve width of "1", which is probably totally wrong for grass. This results in the curves looking like huge ribbons. However you said your curves come in as spheres. That's no something I've seen before. If you attach a simple hip file that would certainly help isolate the issue.

that did the trick, thanks. I think they looked liked spheres because there were millions of them.

Just to slightly add to this..... In HoudiniGL it'll look like huge flat ribbons; in Karma it'll look like huge round tubes with sphere caps, so if the curve is very short it'll just look like spheres.

Also having 'Shade Open Curves in Viewport' turned on in your viewport settings will make curves look crazy in GL
