My Houdini learning thread
grand marshal polycounter
I finally decided to start learning houdini. Its actually not as hard as it seems at the first look, at least after watching the "houdini isn't scary" tutorial series on youtube. It teaches you some important basics. After that, I was able to implement own ideas with minimal google searching, since im still not very samiliar with what kind of nodes you can use. I'm planning to use the software for small things like storing specific data in specific was, pre-scattering things, and some vfx work, and I probably won't make full projects in it. So it will be more like an extension to the toolset I can use. I will post the results as I go here.
The first own project was to make a graph that produces similar results to what pivot painter does, so you can store the local position of sububjects, to be used later in shaders. The most useful use cases in my opinion are usually involving vertex shaders. Advanced foliage animation, pin tables, and stuff similar to that. These are what my results look like:
I also made a little breakdown of the graph, which you can read here:

The second experimental project is to scatter stuff on other stuff based on a texture and some settings. My main use case is to scatter moss on rocks.
The current wip looks like this:
There are still some things to be done, like other than the rotations, I should vary the scale of the moss too, maybe be able to use an optional scale map, but I think its a decent start.

Very interesting stuff, nonetheless, i am also looking into houdini. Could you go into more detail about the setup, specifically what drives the moss spawning?
This is the setup:
About the coding: Its not absolutely necessary to code, but it can simplify some things sometimes. So far I haven't had to code to make these.
Thanks for the inspiration!
Tbh ue4 scattering tools aren't the best compared to other softwares.
