Hey guys did anyone beside me had this issue with displacement ? :
- we 're using small tiled map on object. ( for example gravel )
- object is uvw mapped (planar mapping)
-displacement map and bump map are the same map.
- bump map works good, displacement doesn't -> corona dont see mapping modifier :(

Try subdividing you model.
For me it seems like diplacement isnt able to produce enough polys for a good looking surface.

"Garment maker" isn't very good for subdividing flat surfaces as it sometimes does bad things to corners. Try using "subdivide".

so the more quad polys the easier for corona to generate displacement :) ?

Yes, but this applies to other renderers too.
I did a quick test to demonstrate how much more efficient displacement can be with better topology:

F10 ->  TAB: Corona Settings -> Rollout: Main settings

You have to study better how displacement works. And not only in Corona, but also in VRay etc... Mesh topology is important in displacement :)
