Not Unreal Tools

Modified by yanorax

Vertex Animation add-on tested with Blender 2.83.16 LTS and 2.93.1 LTS

export_mesh.glb tested with Godot Engine 3.3

Changes From Original

Vertex Animation

• Removed UE unit scale and metric system check
• Export mesh UV coords are placed at V = 0.0 instead of V = 0.5
• Frame mesh data is processed in default list order
• New offsets.exr and normals.png image files are saved into a vaexport subfolder in the .blend file path.

Description

A series of tools used to store vertex data in various ways. The data can then used in a game engine to animate meshes via a vertex shader.

Mesh Morpher

Used to store vertex offsets between a meshes shape keys in it's UV layers. Optionally vertex normals from it's second shape key can be stored in it's vertex colors.

Vertex Animation

Used to store vertex offsets and normals of selected mesh objects per frame into image textures.

Getting Started

These tools can be installed as add-ons or ran as scripts. Each tool has a panel located in the 3D View's sidebar under the Unreal Tools tab.

Installing as an Add-on

First download and unzip files into desired directory.

While in Blender open the user preferences window.

Edit > Preferences

Navigate the the add-ons tab.

Click the option to install.
