  1. Group of friends and I are starting a small project, and while we're doing all rigging/animation in Maya, some characters rely on effects that would be much more easily achieved in Houdini. These are generally quite basic, and we're looking to minimise the amount of shot-specific work to be done - I'll ideally write the effect once, and use it over the whole show. Once I have an abc or fbx export, what is the best way of reading that in Houdini to the maximum level of detail? For example, one character has panels of LEDs that form screens, which in turn display depth maps calculated from each LED's normal - there are about four hundred separate LEDs, so ideally I would have a locator for each one, with X facing out the normal, bake out character anim as fbx, import into Houdini and just instance a setup across each locator - I don't know how to do that. Others require things like sparks between contacts, thrusters, etc. How is it best to achieve this? Via Metadata? Naming convention? Custom attributes on locators? The other approach is to use HDA in Maya, which I know nothing about - ideally would like to keep the two separate, if nothing other than to make look dev easier. Let me know your ideas. Thanks!
  2. Simple project to learn Houdini

    I'm new to this place, so apologies if I'm being dumb about anything. The project is to fire a beam at a piece of geometry, and have it fracture at the point of impact, like a simple sci fi gunshot. I have a rough idea of how to do the destruction, but which nodes should I use to cast the ray, and then find the intersection? Also how do you even define a direction or a vector to start off with? Currently I'm using a very long single-span curve, but I'd like to find a way to cast the ray infinitely. Any help is much appreciated. Thanks very much.
