I was trying to add a parallax map extends MeshPhysicalMaterial, it worked somehow but I got some problems: https://codesandbox.io/p/sandbox/three-js-parallaxmap-physicalmateiral-zygw7q?file=%2Fsrc%2Findex.ts%3A587%2C21 [0ac7f41c81e9c38d1a34ff867ec7ce66] the first is that, I set the camera posit…

It hasn’t the addition of extra searches that increase the precision dynamically. If you look at the example you see it also gets visible layers on steep angles, you can hide by increasing the steps, if the issue disappears by increasing the steps it’s related to that. But might be also related to i…

thank you for your infomation, I’v set the step to 32 in my example, and the line artifacts happend on M3 MBP, and my windows pc don’t have the artifacts too. so maybe its because on M3 MBP, the percision is lower? how it could happend , I find out the lower hight on height map were fine(the white p…

It doesn’t seem like general precision then but rather hardware related or at least both then. You can try track down the issue by removing parts, or securing parts from division by zero and such to track down the part causing the artifacts. Also trying to change the height or normal map for testin…

May be related - most likely a precision issue.
