This post is about the changes in Pipeline and features between UDK and Unreal Engine 4.
Why this post ?
Because I am transferring 2 years of work (assets, shaders, Unreal Scripts, etc…) to the New UE4.
I am of course having issues, and solving them takes me time.
So i want this post to be a reference to you so you can save time.
edit : I will be editing this also, new found (Thanks
I will report back here very often these days (End of March 2014) to add corrections or content.
If you have some feedback etc… i will add to this first post right here.
Please post your verified experiences only. This is not a solving post. It’s a reference, and what you can do to have similar things from UDK to UE4.
Materials :
Emissive : In not enabled in the Mesh property in the level anymore. It’s inside the material. (advanced view option need to be ON), it’s dynamic,
Specular : You can specify a color into it anymore. It need to be a “metalic material”
Geometry(meshes):
-Collision name have changed in your 3d apps
The UCX now need to have the same name than the main geometry. UDK : MyMesh, UCX_MyCollision was okay. EU4 : MyMesh, UCX_MyMesh_## The name need to be the same _## is a number in case you have several UCX in there
-No more .ase .psk .psa (from ActorX)
Go Fbx (2013)
Lights, lightmaps, lightmass:
Emissive doesn’t emit photons anymore (will not show in lightmaps)
