Project curves onto a surface in Houdini

In this quick tip for Houdini, we show you how to use the Ray SOP to project curves onto geometry.
The key to this is to set the normals of the curve to point towards the surface of the geometry, then use the Ray SOP to project the curve onto the geo. Once this is complete, you can use the Polyframe SOP to reset the curve normals so they are suitable for use with a Sweep.

HI WHERE DO I FIND A PIRATED COPY OF YOUR TUTORIALS AS I HAVE NO MONEY

[@Helloluxx]

Hey Sonny, I checked your KZbin channel and to be honest, you do have a lot of work to do, but if you practise a hell of a lot and try a lot harder then maybe, just maybe, you'll get good enough to make some KZbin intro videos! Then once you've you saved enough cash you can purchase the training legit. In fact, if you do manage all of that, as a reward I'll give you a 25% off voucher code, so you can buy it at a discount.
