Thanks Olivier! I like the neighbour / Mexican wave idea. Do you know if a ray sop would be the best place to start? in soft I would use a find neighbours, or get nearby points. My other idea was to just activate them with radius of a null (always forget what you call them in houdini), But it might be more natural with the "neighbour" idea G On 06/03/2015 09:58, Olivier Jeannel wrote: > Hey Gerbrand, > Not a tutorial but an interesting article from Yancy Lindquist he > talks a > bit about Frozen. > http://www.fxguide.com/featured/rise-of-the-effects/ > Might inspire... > Le 6 mars 2015 08:39, "Gerbrand Nel" <g at cannonballbunny.com> a ?crit : > >> Hey guys >> I need to jump in at the deep-end with houdini, otherwise I might never >> get the confidence to tackle a job. >> A client has asked me to create frost on someone?s skin. >> Imagine Elsa from Frozen looses her shit, and sneezes on someone. >> So its a kind of spreading, time-lapse hoarfrost.

Use a sop solver to have a frost attribute creeping across the mesh. (use some type of pc lookup to get the frost to spread, add some noise in too... what ever works). Time shift your mesh to one frame so it is static then attrib copy it back on to the animated mesh. You can also do it with a points in a sop solver, add some noise to move the point, use an SDF of the mesh to snap the point to the surface then repeat. You can get some nice patterns of creeping tendrils that way. you can then attribute transfer the frost attribute from the points to the mesh. Once you have the attribute you can use this to grow fur, then add a poly wire sop to get the crystal look.

One question though: At about 6min he talks about a attribWrangle_adjust_range node. He has a

Thanks for Francois for that explanation. In regards to HDA there is something I am struggling to figure out. When you copy and paste a HDA from one scene to another, the node works in the new scene but I get the following error *"This node is using an incomplete asset definition. It will not function properly until the asset library containing the full definition is installed"* This error then pop ups everytime I open the scene.I guess the HDA is not defined on my new scene, but how do I get around defining it from this copied asset? I am trying to avoid rebuilding the nodes, but I know this is an option.. Hope this makes sense.

Hi Houdini Braintrust, Out of curiosity I did the tutorial as well, but when it gets to the section where it bypasses the fur length inside the fur node, I couldn't locate those same nodes in the current fur system. I clicked the "paint density" button, to see where it would add those attributes, but bypassing those still doesn't get the node to look for the "fur length" attribute that was customized. Any ideas? There is also the possibility of using maps, but then I wondered how I could generate a map from the density simulation we have going on.
