I've been trying to come up with a way to do scales in Houdini for some time. It all began when I learned that VFX studio Animal Logic developed a proprietary tool called RepTile for the movie Walking with Dinosaurs. RepTile allows artists to both manually and procedurally groom scales. It also allows scales to be rigid and not stretch while the skin does. A paper talks about the tool but doesn't show exactly how the process is done. A video shows an initial test of RepTile. A video shows another test where the skin is colored red and the scales are colored green to show the range of stretch. A video is a behind the scenes video for the Walking with Dinosaurs. It talks about RepTile at 0:19:12. Here's what I want to know. 1. How to render a subdivision surface as a scale in render time? 2. How to generate scales on a surface, have them stay flat, and not stretch as the skin does? 3. How to use curves to influence scatter points on a surface. 4. Should I have a triangulated mesh for the scales to grow on? 5. How scales can be shaped to fill their polygonal outlines? Any thoughts would be helpful.

Hello. I'm making a simulation of dripping candle wax, and I'd like the droplets to start out watery and transparent but become opaque and waxy as they solidify. For reference, see the puddle of wax pooling around the flame compared to the rest of the candle. To do this, I am using a custom temperature attribute, which is bound to the transparency and roughness values on a principled shader, like this- For the most part, this gives me the effect I want. However, in areas where the temperature approaches its maximum value (100), the material looks black and burnt. Does anyone know what could be causing this? It's frustrating, because I very nearly have the effect that I want. Any help would be greatly appreciated! Here's my project file: CandleWax7.hipnc
