Hi. how can get a perfect displacement in corona
I decrease in Render setup / performance / displacement.
line 1 px or in world size unite a little like 0.005. but corona give not me a perfect displacement
what I can do/??!
That looks like perfect candidate for displace modifier:
For a moment there Romullus I thought somehow you had turned your performance graph into displacement 
Hmm, interesting idea, but wouldn’t that create circular dependency? :]
thank .thats great but i cant re topology my project. its give me very time . many thanks
so how can solve? I cant re topology
You can try to blur displacement map a tiny bit. If it has too hard transitions between extreme values, then you will always have artifacts, no matter how small displacement size you will set.
