This is also critical for me as the only light source I had in UDk were emissive materials.
I cannot get photons to fire up with lightmaps or even in dynamic lights.
My whole lighting pipeline was based on material lighting, I am very very annoyed by that. I must find a solution to that.
I looked at every example provided. Read all the post on the subject too, cannot find any equivalent.
I became on expert on that on UDK.
Neon in subway map, but it doesn’t light up the scene (“light only” shows no influence)
It look like UE4 became a realistic architecture lighting software. I want fantasy, and SyFy, not “welcome to Autocad”
I’ll comeback here reporting when I find a solution…
Edit : Yes I saw that post. But “feature removed” without an equivalent is a mistake… (for content creation variety type)
