Thanks a ton Mads, really appreciate the help :- ) Here is another method as well with Corona renderer: https://www.youtube.com/watch?v=RGSEgFJDqjw&feature=emb_logo
On a train, can't see the vids. Do you mean in the viewport while you work, or at render time? For viewport, yes. Use Shader FX, works basically the same as Unreal.
@Amiminoru This is excellent. Thanks for posting. Nice to see ue4 techniques in 3d modeling programs for offline rendering. Any chance u could pls share the material setup for eevee in Blender? @MadsD Pls, is there a way decals can be projected on surfaces like ue4 with osl shaders? Also parrallax mapping?
You can get it to work both in viewport "live" and for rendering, but you would need to setup two separate shaders and feed them into a master Shell material. You'd also probably want to wire up controller nodes to change both settings at the same time, like height cutoff level and blend sharpness. Then you could use…
EDIT: I actually posted this message long ago, it just needed to be verified for some reason (probably cos of the link) so now it's way late and I look like an idiot. :) To avoid having to do the material twice with a Shell material, OSL based shader networks in newer Max versions are supposed to work in both viewport and…
