@Ryan> Done some digging around on the CryEngine forums:
Silhouette POM is actually what they call PADM.
Bit confusing but at least we got that one clear now (doh!)
Known issues:
- Indeed a requirement to have it work properly on hard edges is to chamfer them a bit.
- It’s the most expensive form of all POM’s but still cheaper than tesselation
- Can have issues with UV’s & Artifacts and will thus require more tweaking for optimal results
