Unity - Accessing All Children Objects Throughout Entire Various Sized Hierarchies

September 4, 2019

Accessing Full Gameobject Hierarchy

Unity

StackOverflow - Get All children, children of children in Unity3d
Link #1
Unity Answers - Find children of object and store in an array
Link #2

For a project we were looking into applying a material color change to some more complex Unity objects/models which are made up of many children objects with many materials. To do this, I needed a way to be able to grab all the materials all throughout a gameobject's hierarchy and change them simultaneously. This led me to think of a recursive approach, and sure enough there was already one explored that I could reference online in Link #1.

Link #1 also showed me a useful feature that I did not know about Unity. You can use a foreach loop on a transform and it will go through all of the children transforms automatically. This helped make the recursive solution much easier to read, and is just a good feature to know about in the future.

Online Multiplayer Networking Solution Tutorial Using Unity and Mirror - Tutorial by: Jason Weimann

February 2, 2021 Networking Online Multiplayer Unity & Mirror Title: Let's build a 4-Player Networked Game LIVE - Online Shooter (with Mirror & Unity) By: Jason Weimann Youtube - Tutorial Description: Intro to using Mirror for networking online multiplayer play in Unity development. Introduction This tutorial has Jason Weimann implementing online network play into a basic Unity twin-stick shooting game. They use Mirror, which is a Unity asset used for simplifying the online network synchronization process. This is a live implementation where they work through many errors transferring a game from simply working locally to working with a host/client relationship. Mirror Mirror - Home Page Mirror is "a high level Networking API for Unity, supporting different low level Transports" (from Mirror themselves). It is a clean solution for implementing a quick and simple online networking option for Unity projects. The core components breakd

Exporting FBX from Houdini with Color

April 17, 2019 Exporting From Houdini FBX and Color Information Exporting the Model Using my balloon Houdini example from class, I was able to export the geometry using the Educational version (the Apprentice version does not allow exporting FBX, but you could export an OBJ for my purposes possibly). This was very straight forward, as you can just use File -> Export -> FBX in Houdini. Since I was doing this for a class to use in a Snapchat filter (using LensStudio), I wanted to reduce the poly count a lot. I opened the FBX in Maya and used a basic Reduce to reduce the poly count a lot before exporting that for use in LensStudio. While this was good enough to export the geometry, I could not get any of the color information to come with it. I originally exported out an OBJ and had the same issue, so I exported FBX in hopes it would keep the color information somehow, but this was not the case. Exporting the Color Information My first thought to get the color

Houdini Assignment - Fuse and Group

April 8, 2019 Houdini Assignment Fuse and Group I worked on a Houdini class assignment to make a basic model and decided to try and create the bulb on the back of a Bulbasaur, a Pokemon that is half plant and half dinosaur. I figured I could use a lot of the basics we learned in class to get me pretty far, while also needing to cover a few new things to get it exactly how I wanted it. In class, we created a basic hot air balloon. This consisted of tracing a curve over a background reference image of a hot air balloon, creating a section of the balloon from this original curve, then replicating that section as many times as needed to fully encompass the full balloon. These were a lot of principles I used for creating my bulb. The biggest hurdle I needed to overcome was that that top of each of my sections would all need to connect at a single point, so I would need some additional nodes after simply creating a "left" and "right" variation of my addit
