the following video shows a shield effect:
it was made for UDK, in the description of the video there is the archive that allows that effect, is it possible to convert this archive in a format that is readable in unity 5 ???i asked this before, but was censored, this time can some one anser my question please ??
No - you can’t “convert” a UDK archive to make it usable in Unity.
I’m not a UDK user but, from a trivial Google search, it seems that UDK custom shaders are written in HLSL. Unity’s shaders are written in CG, which is basically identical to HLSL under a different brand name. So it should be relatively simple to rewrite the shader in Unity.
The wikibook linked by @meat5000 is a very good place to learn CG shader programming, and there are plenty of other resources too.
