Parallax mapping option as an alternative for displacement
MattiasD:
Decals (geometric and projected) and POM are the reason why I`m looking at Unreal or Fstorm. We used them extensively when working on Homefront: The revloltion (made with cryengine).
They are a quick way to add damage, dirt, markings, puddles, posters, edgwear, cracks, flat elements, ..
They are highly reusable.
They fit in your ideology of "Ease Of Use" (https://corona-renderer.com/features/ease-of-use)
And i`m tired of trying to achieve similar results with distance maps or ambient occlusion :)
And all though the displacement in POM is not real it does a really good job most of the time.
BIG +1 if this could be implemented.

I imagine a good implementation of decal/material projection in Corona would be a really fast way of adding unique detail to base materials.
Not sure how parallax mapping factors into this, but I imagine it would be faster than using displacement - especially when developing the look of your scene and you want to move the camera around. Displacement really only works on the polygons that are visible to the camera when you first activate VFB, doesn't it?

parallax bump is essential for using decals with negative surface level such as cracks just because u need to avoid intersections with the base geometry)

Hello,
I've tried the max file, as soon as i'm putting a bitmap in the OSL file name, it hangs (not crashed, but 99% cpu, even after 15mn), just trying to render the normalMap node.
I first thought it was because of my disp map set to 16bits, but it does the same with a simple 8 bits jpg.
Any idea ?

must upgrade Decals with this

Hello, could you please explain why using displacement or normal map is not enough? Why parallax mapping would be better in this case?
