I have this Grid (400x400) (row 300 and col 300). I added 'attribute noise' with default setting and set Amplitude to 100 and element size to 400. This is the output :



But when I set the 'offset' to very high number such as 100000, then the shading starts to break :



I think this 'offset' parameter should only control the offset of the noise not affecting the roughness at all. Why did I got this output ?

that large of an offset causes the noise space to run out of numbers due to catastrophic loss of precision. 32 bits only gives about 6 or 7 decimal places of precision, so adding a 7 digit number leaves you with 0 decimal places to work with.

Thanks for the explanation.
