BLENDER TREES FOR UNREAL ENGINE 4 HOW TO
PGMath posted an article on blender.stackexchange on how to recreate the Mapping and ColorRamp nodes using simple Math nodes, a huge help!Ī massive thanks to batFINGER, CodeManX, and sambler for their countless contributions over the years to blender.stackexchange!Īnd thanks, of course, to Epic Games, and Blender Foundation! Example output (GroupTest1_TM.py): Momchilo has pitched in with some licensing resources. Jim Kroovy submitted a crash fix, and a refactoring suggestion. Acknowledgements and ThanksĪngjminer's Project BlUEMan demonstrated a similar functionality a few years ago, this is an attempt to achieve a similar result using an open framework. This can sometimes be resolved by ensuring the position of the first colour is 0, and the position of the last colour is 1. It redirects stdout to create the python file, so if you are printing to the console, it will interfere with the script.Ĭolor Ramps are supported, but above 4 colours they start to produce unexpected results, with colour banding and other issues. Some very common Blender nodes are not yet supported and it will take time to figure out the proper Unreal equivalent for all of Blender's Nodes. If you use a node that is not on the supported list, your material will likely not transfer properly. Node groups work with the 'Transfer Material' function, but, for now, in order to bake textures in Groups, the groups must be broken. Packed images will give errors, use textures that have a filepath that exists on your PC.īump nodes will transfer, HOWEVER, they cannot accept an RGB input, so you must create a Texture Object, manually load your texture into that, plug that into the node, then attach whatever you are using as a texture coordinate, to align the textures.

BLENDER TREES FOR UNREAL ENGINE 4 MANUAL
Mapping nodes will transfer, HOWEVER, results are not yet consistent with Blender, and manual adjustment will be necessary. I'm planning on first getting all the nodes that have direct equivalents sorted out, then looking at nodes that require custom coded solutions. If a node is in the unsupported list, it doesn't mean it won't be supported, only that I haven't yet found a way to port it over. Group - Partial Support - see Limitations TextureSample - your baked texture will auto-importĪnything NOT in the above list can be considered unsupported, however, there are some common Blender nodes that do not currently have support that are likely to be in many materials, those are explicitly stated below. Procedural Texture Nodes (via Bake Noise Nodes) Transmat will find and import all the image textures from your Blender material, and plug them into the right nodes! Currently supported Blender Nodes Blender Shader NodeįunctionCall - BL_ColorRamp - see limitations Navigate to the python file that was just created, and click 'OK' - eg 'GroupTest1_TM.py' This will setup the custom Mapping and ColorRamp nodes in Unreal. NOTE: If this is your first time using the addon, navigate to the TransMat folder, select 'TransMat_SetupScript.py' and click 'OK'. Then, in Unreal (with the Python plug-in and Editor Scripting enabled) click 'File' > 'Execute Python Script'. This creates your material file - eg 'GroupTest1_TM.py' Now, click the 'Transfer Material!' button. Transmat then checks the output connections of the noise nodes, and replaces them with your newly baked textures! (eg Brick, Checker, Gradient, Magic, Musgrave, Noise, Point Density, Sky, Voronoi, Wave, White Noise)īe patient if you have a lot of noise nodes and you're baking at a high resolution, it will take time! Next, if you're using procedural noise nodes, you can choose your resolution, and bake them to textures. If you do add a subfolder, the script will either find it, if it exists, or create it, if it doesn't. If you do not specify any folders, they will go to your game's Content folder by default. Then, if you wish, you can specify Unreal import subfolders for the material and textures to be placed in. Once you have created your material, choose a directory to output the python file to. This will add a properties panel to the Node Editor.
BLENDER TREES FOR UNREAL ENGINE 4 INSTALL
It creates a python file that will instantly, automatically recreate your Blender material in Unreal.Ĭheck out the example at the bottom of the page to see what it looks like! How to Install and Useĭownload and unzip the file, then, in Blender, click 'Edit' > 'Preferences' > 'Addons' > 'Install' and choose 'Transmat.py'
