Pixel Depth Offset alternative for ray tracing?

jordank95

I can't seem to get pixel depth offset to work with ray tracing. Assuming it's because of how ray tracing works? Not sure of the technicalities of this (if anyone could explain that would be super helpful). Is there a method to get things to blend into my terrain with ray tracing?

Yes, try virtual texturing.

Thanks! This is exactly what I was looking for. Ray Tracing in UE is a whole new field for me. Looked into this and tried to implement it into my master material and UE crashes every time I hit apply. Using 4.25.

Crash is "assertion failed d3d12resource" 

Here's my material setup:

I'd recommend watching this video. Distance field isn't needed for this. Thats like shooting at the problem with 2 guns.

Also, do you have editor symbols installed? That would enable you to get full crash reports so it would help identify the problem. I used ray tracing with virtual texturing several times in the last couple of months. I did run into occassional crashes, but it seems to be mostly usable for me.
