Distortion on parallax-occlusion-mapped objects

[SolB]

Pretty minor issue, and I don't know if this is an issue exclusive to this model since I can't find many models with this shader aside from this one that can be viewed this close up (since I'm now noticing POM is used on lots of models and decals and it looks really cool), but the parallax-occlusion mapping effect tends to break from certain angles. I'm going to take an educated guess that its because the whole object is extruding outwards, rather than being a modelled cylinder with the flower design inset via POM.

I think its because of the fact that its a parallax map and not an actual geometric displacement, that when the part of the texture that is extruded gets covered by the corner bits then the extrusion breaks. it being an inset like you said may fix it, but I think they may not have done it for the fact that they wanted the collision to basically follow the rest of the wall face. That said, they could probably fix this in the future, this was probably the quickest way to add depth detail without affecting graphics optimization or having to render the depth map as if it was geometry.
