My name is Nikola Stojanovic and I work at Faculty of Electronics, Nis, Serbia . Our students made this model, special thz goes to student Miljan Sakovic who help us a lot, at first it was transfered into Quest 3D engine, Turtle rendering engine . If u r interested I could post some videos and pics later.
Model is just exercise for a much bigger project that we are preparing.
Mesh was made for Q3D engine and I just exported to Unreal engine.
It is merged by the parts of the building like u see in the picture and have two UV channels.
I suppose that because of that I have some problems with Lightmass because Unreal supports modular design and we made it merged.
Problem is that when I try to increase indirect illumination to lighten up shadow areas, strange paterns start to show and become more and more noticeable.
I have tried to decrease static lightnning level scale hoping that I will shoot more photons, but every time I do that paterns become more visible.
Also when I increase DifuseBoost, color bleed go wild.
These are the settings that I have right now:
I am expirienced in MRay and Turtle render, but I am stuck with Lightmass. Some discussion would be very helpfull
thz in advance
