Problem with displacement mapping I wanted to model a pyramid with a tiled panel look using blender 2.8. I don't want to use the displacement modifier, only the displacement mapping from the renderer. So, I unwrapped my pyramid using top view projection and created a black and white displacement map using inkscape:


Then I've set up this material:


I activated true displacement from cycles options but my pyramid is now completely distorted:



I'm probably missing something but I don't know what. Any help would be greatly appreciated. Here's the file:



Thanks,
As metaphor_set said, you need better geometry, and more of it, for good displacements. That's your issue here - it's trying to displace the geometry as the map is telling it to, but there's only 5 vertices to displace.
