Is Parallax Occlusion Mapping self shadowing broken in 4.24?

anonymous_user_72ac72801 · January 16, 2020, 3:40am

Even the content example of POM self shadowing is not self shadowing in 4.24.

Can anyone else confirm this in the content example?

Yes, it is broken I’ve opened the Content Example in 4.24 (left image) now and it’s not working, and just to confirm I’ve opened in 4.23(right image) and its working fine:

I also found the same issue in my level. May I get the fix version on 4.24.4?

Oh this issue still present in 4.25, I have reported this on feb and nothing, So what I did to fix that in the 4.25 where open the Parallax Occlusion Mapping Function from 4.23 copy everything, create a new Material Function in the 4.25 and paste there and it worked like a charm.

Yes it is still broken. Target fix is 4.26.

Interesting that worked, good to know!

I doesnt work for me… Is there an easier way to get POM shadows working?

dirtydanisreal · November 6, 2020, 9:04am

Unbelievable!!! Thank you so much!!! POM shadows were also broken in Unreal 4.27.2, and it was literally as easy as double-clicking to open the main ParallaxOcclusionMapping function, clicking on the green “Parallax Occlusion Mapping” custom expression and adding 2 forward slashes (//) in front of the shadow = 1; entry so it looks like //shadow = 1;. Then save and close the function. I double-checked in Unreal 5.2 and this is literally the same fix which was implemented there!

A huge thank you to @dirtydanisreal and @Setihome for finding this fix!!
