When you have finished apply your bone mapping and click done. You can drag and drop bones from the Hierarchy tab into the bone mapping window. When in the bone mapping window, the entire parent-child bone system will be unwrapped in the Hierarchy tab. The second will require manual bone assignment. The first problem can easily be fixed by clearing the jaw bone assignment. Two common errors to look out for are: Assigning a eye bone to the jaw bone and not assigning purposely unweighted bones. This is usually caused by incorrect bone merging in the modeling process. If the assignments appear correct then you may need to fix the model in a modeling software and re import the model. If the model becomes disfigured check the bone assignments. You can test if the model is setup correctly by enforcing T-Pose at the bottom menu in the Inspector tab. Unity is very good at automatically and correctly assigning the bones for a humanoid rig. You should be brought to the Bone Mapping window in the Inspector tab. Save your scene because all software used for creative purposes is infamous for it propensity to crash. Then change the Animation Type to Humanoid, then click Configure. Three new buttons will appear in the inspector window Model, Rig, and Animation. Near the top of the inspector window will be a button called Select, click on the Select button. Details of the model will appear in the inspector tab. Be sure to click on the highest level parent of the model. Child objects can have child objects of their own. Unity uses a parent-child system for all game objects, clicking on the grey arrow next to a object in the hierarchy will display its child objects. To do this we will need to click the model in the Hierarchy tab. Models that are not set up as a humanoid rig will slide around in game in their default T or A pose. Next we will need to set the model up as a humanoid rig. Shaders and Textures will be covered in part 4. If it is clear or white it is missing its texture. If your avatar is Purple/Pink after you have added it to the scene, this is a shader issue. You can always adjust your view in the Scene tab with the mouse scroll wheel, center and right mouse buttons. You are also able to do this in the Scene window to alter these values visually. You can manually type the values into the component. The Transform component dictates an objects position, rotation, and size. To do this: click on the avatar in the Hierarchy, this will bring up the models components in the Inspector (right) tab. It is recommended to set the avatars position to zero, though it is not necessary. With our avatar successfully imported as a unity asset, we will now add it to your Unity Scene.ĭrag the FBX file from the Project (bottom) tab into the Scene (middle) or Hierarchy (left) tab. When importing models be sure to include the models texture files, these will be image files of varying formats, with the FBX. FBX is the prefered model format, though other formats can also work. Non-asset store models can easily be added by being drag & dropped into to Project (bottom) tab into the list of assets. You will have to be logged into your Unity account to download assets from the asset store. Click on the Asset store tab above the scene window (center window). You can find Unity-Chan as a free asset on the Unity Asset store. You can check the number of polygons by importing the model into blender. If your avatar has more than 70,000 polys you will need to decimate it down to a lower poly count. VR Chat requires all avatars have less than 70,000 polygons. This will be covered in the intermediate guides. That being said, the de facto tool for preparing models before import to unity is blender with the cats blender plugin and mmd tools plugin. ![]() The goal of this tutorial in addition to learning how to navigate unity is to also teach you how to troubleshoot when things break. In this tutorial we will be using Unity-Chan as our tutorial avatar. Once logged in the window will also display if you are allowed to upload avatars. A new window will appear prompting you to log into you VR Chat account. ![]() Go to the newly added VRChat SDK option in the main menu -> settings. After the package finishes uncompressing, a prompt will appear, click Import.īefore proceeding, you need to log in. Go to the assets option in the main menu -> import package -> custom package. The personal version of Unity is sufficient for creating content on VR Chat. ĭuring the Unity instal you will need to create a Unity account. The necessary version of unity and the VR Chat Unity SDK can be downloaded by logging into and proceeding to the download page.
