yes, I used couple other textures one thing I noticed with textures that have noticeable height difference like cliff materials this effect is nearly unnoticeable, bit with materials that are kinda flatter like this one and brick materials this always happen.
as for the material Im no shader expert first time I experienced this I was using William faucher’s master material “easymapper”, but all the results I saw in his videos and other people were really clean and nice, I tried to make a simple shader to see if this problem will persist in a new project in the latest version of unreal 5.4.1 I, this weird effect is still there.
That is the latest shader I used with the previous screenshot, is there something Im missing here or do I just need to tweak the values u mentioned to get rid of these spikes?
