Displacement/Tesselation

[jessewisener]

I'm having trouble figuring out how to make it show up in the viewport or when running the game. The only place I actually see it is in the material editor and the preview in the assets window. I searched the documentation for an answer and couldn't find anything...

This is kind of a challenge because you need a certain polygon density to start out with. The teapot model for example has this. A brush, on the other hand, will not. If we can figure out a way to subdivide the surface based on triangle size in screen space, that would solve this problem.

 

The other issue is that since tessellation is a shader effect, and the renderer reverts to a simple shader when drawing in wireframe, it won't show up there. You can get around this by adding this secret line of text to the material file contents:

alwaysuseshader=1

 

The easiest way to see the tessellation effect is to drag the teapot into the scene and then apply the material, and it will be very visible.

 

In other news, I just got permission to include some high-res scans in the engine media that really showcase the effect.

Thanks Josh! Polygon density makes sense. I'll go bump it up in Blender. I'm excited to see those scans.
