No. Umodel is not reading MaterialExpressions, there are 118 classes in January 2012 UDK! Also, there is no data format exists to export, and no application to reimport it back.

Sorry to necro a post, I just want to clarify:
I was trying to get meshes from Umodel to find their Textures automatically (when importing using ActorX etc. into 3ds Max...) and I should look in the Mat's accompanying TXT files, (which do indeed list the texture placement and name!) and place the textures manually? It is of course a bit harder to have any additional step with thousands of objects (one of my 3 projects, is recovering as many assets as possible from a game made by friends, after most of the original assets were lost in a fire,..) but it is so great to be able to access so much that was thought lost.
They will be over the moon, I will be sure to suggest your Paypal etc. to them when I reveal the results! ;~)
OH if only recovering MAPS were possible! The elaborate worlds they had made over many months,. I always think Blueprints are relatively easy to reproduce, you know it's just logic, ... this, does that, does this,.. but Maps, maps are the real ART,.. The time and detail,..
Gildor, I am pulling everything into 3dsmax first, (optimizing what was put together very fast the first time,. Etc...) is there some best material to use as an 3ds max > Unreal 'intermediary', (that will use the Specular Noise and Normal files coming out of Umodel Etc.) and will import into Unreal with no problem?
What you are doing is amazing,. The updates are surprisingly often.
Very cool. THANK YOU!!!
OH! I read your about me page. WOW!...
I wonder how many people accept your help, and never know the multi-faceted and impressive individual they are .. addressing..
UPDATE: Got it! I was moving Mat files and Tga files to the same folder, thought I had tried everything,. It never occurred to me to point it to a 'empty' folder of other folders!
BUT: it liked just being sent to the folder that contains both the Textures (meshes) and Materials Folder (and 'Look in Subfolders' checked!) THANK YOU!
