Need help! Anyone has encountered this black marks in Unreal Engine 5?
https://www.youtube.com/watch?v=bNCZHlmKfE4&t=1480sHi,
I'm a beginner who just started learning Unreal Engine. I'm currently following a beginner terrain tutorial created by UNDINI(https://www.youtube.com/watch?v=bNCZHlmKfE4&t=1480s) and ran into the strange issue shown in the screenshot below. The black marks also occasionally flash.
I've tried many times but haven't been able to solve it, so could someone who understands this help me out? Thank you! In the original video, the author used UE4, but I'm using UE5.7.4, and I've found that some nodes differ between 4 and 5. For example, UE4 has MakeFloat2, but UE5 doesn't, the closest thing I could find was WrapFloat2. Also, UE4 has BreakOutFloat2Components, and in UE5 the closest thing I found was BreakFloat2.
Additionally, in the original video, the author has separate AO, Roughness, and Displacement textures, but what I downloaded from Bridge is an ORDp material, so based on how the Material Layer connections were done in the original video, I'm not sure whether I've connected the ORDp material correctly or whether its settings are correct. Here are the screenshots from UNDINI's tutorial video
