I'm running into some weird behavior using the guidegroom node in Houdini 20.0.653 (and 547 before that) with the Plant tool. It seems to always create new guides with a bend between the first and second points, as if the guide were stuck to the surface until the second point or something. I've tried it with as many different options combinations as I could think of, with and without Collide with Skin, Use Mask, Single vs. Scatter, various combinations of the Interpolate Guides, Relative to Skin, and Orientation options, different Template options, etc., and nothing seems to change this behavior. I'm NOT seeing it on a simple sphere example, only on my more complex model that I actually want to groom on. Does anyone know what might be causing this? The green arrows are pointing to the planted guides that are all J shaped, as opposed to the originally scattered ones generated by the obj guidegroom node. Please and thank you for your help! I'm on Windows 11 if that matters.
