POM material

Hi ,
Firstly, I’d like to thank you for sharing POM function. But what is a proper way to get it working with tri-planar texturing? What I’ve done so far is modifying WorldAlignedTexture node to calculate it 3 times, however it results in correct parallax direction only on one side of the cube. Other sides have parallax direction inverted.


How can i overcome ? And do I actually need to calculate the parallax 3 times for ?
Thanks in advance!
