I already had a new build of my tool able to convert T3D materials, However there is a major roadblock preventing material support, Despite the fact you are able to export materials as T3D files out of the engine, Importing T3D files back into the engine is limited to only importing actors into the scene, and not creating new assets like a new material.
I’ve posted a request on the answer hub and it’s been added to their internal database but who knows when, if ever it will be implemented.
UDK’s material editor does not use T3D to copy nodes, while UE4 does. While it may be possible to take an exported UDK T3D material, and convert it to T3D you paste into UE4’s material editor, the problem is the T3D generated by UE4’s material editor is needlessly complex (it manually defines the creation of each node/pin) that would require a significant amount of work and I’d have to manually create support for every single node.
But actually it may not matter because Speedy37 released a UDK import plugin that supports materials because its an actual UE4 plugin. However my tool supports more actors than his.
@xvampire, Yea that is weird results I have not seen before, can you send me the output you get from UDK? I’ll need it to track down the bug.
