Just a quick question.
I've had parallax occlusion mapping implemented for a while now, but I soon realized that problems came, not every artist wants to create a parallax occlusion compatible map just for some bricks, they've already made some normal maps, but unfortunately they aren't compatible. (Not that I know of...)
- So how would you be able to convert a normal map to a pom map in realtime, preferably in hlsl?
- Is the performance worth it?
I've seen some offline examples, but again, is this possible in runtime?
Thanks, as usual.
