Does anyone knows how can I get the name of the texture on a trace?
For example, on a vertex painted “vines” wall, I want to get the texture name to know where my character can go or not.
I do not however I believe you can get the Phys Material from a trace and break hit…and Phys material is how FTC got this working on his Adv Kit for UDK…
Yes, but the problem with this, is that fot that situation on the picture, I will have to use two materials, instead of just one. If we could have an option to return the texture under the trace, for this we would use only one material. 
I made a request for this on the feedback forum: [REQUEST] TAG string for textures in a material - Feedback & Requests - Epic Developer Community Forums
