displacemant change in animation

[rendermax]

Hello as You can see in attachments I use displacement for grass. But Iam really suprise that in animation dispalacement map change. I try to use nois map or nois bitmap created in PS, but it was the same problem, maybe less changes if I use bitmap. Any help pls? Thank You

In Corona screen size displacement is adaptive and that makes it problematic to use for animation. Switch to world size displacement if you don't want it to change between frames, but be prepared for big increase in RAM usage.

BTW, is there particular reason why you decided to use displacement for the grass instead of geometry? In most cases geometry would eat less RAM, would render faster and would look much better.

Hello, I try it whit world units and its not possible. Like You said, RAM gos creazy :)
Well I chose displacement (like in old days) because I had problems whit 3d grass and edges. Need to find some solution.
Thank You

Is the correct process when rendering an animation to switch to world if the flickering is noticeable? Thanks

Hi
Forest Pack has solution for edges - Ares->Boundary Checking->Edge . It works well with Corona. Only thing - you have to make your base objects of grass areas as thin geometry - plane polygons to get real edge of base geometry to make this function to work. It's real time saver wherever you need to have clear borders of grass areas
