Parallax Mapping

[ftesla]

Hello,

Is it possible to create a Parallax Mapping effect with a height map and a normal map using Arnold ?

(DECALmachine for Blender)

Hi @ Max Hi @ Mike

I actually managed to make the OSL shader work!

The trick is that it needs to use aiImage nodes instead of the default Maya File nodes, as the Maya default nodes do not allow UV cordinates manipulation (as far as I understood).

There is no OSL Parallax Occlusion shader that supports PDO and Silhouette Clipping yet.

These features are quite awesome and very convenient for large scenes.

(it would be amazing if Arnold would develop something like this).

Hi,

would it be possible for you to share your shader? I can't get it to work right.

I actually tried, and I succeeded in restoring the parallax effect perfectly. However, I definitely don't recommend you to do this. This rendering is super slow, which is super cosmic. I posted a post on the forum, and it needs to superimpose nested nodes many times, which even makes maya files directly damaged and can no longer be opened, and the whole scene has only a simple plane.

Still a bit problematic but should end up in rtoa v2.0 ! Sure it's super fast !

Last interaction in the video is with Detail Suppression mode set to Smart .. it filters high frequency details for better depth effect.
