Title: Displacement problems
Post by: filipskrzat on 2014-09-21, 18:46:10

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 :(

You have to creat a good quad mesh.

this is very simple mesh :( made of extruded box

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

create a spline and modif. -> Garment Maker ---> and Displaisment .

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

try this ;-)

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:

where i can  adjust maximum mesh subdivision ;> ?

Render setup>Corona Settings>Main settings>Max subdivs per poly

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 :)
