It turned out that the troublemaker here was a power fractal shader that I plugged into FS surface shader on its own! Not its displacement!What caused trouble was feature scale and smallest scale of the fractal pattern. I reduced them to a very small size because I wanted small stones with adequate, spotty surface. Below certain values TG was going bonkers. It's probably due to the fact that it cannot render that sort of detail from such a distance (there's about 6km from camera to the fake stones that you see in the image). These seem to be minimal values that I can apply to fake stones' surface without any side-effects:[attach=1]Problem solved.

Quote from: WASasquatch on January 03, 2015, 05:18:18 PMOf course you can force it... but if you notice.. you can write in the amount, like 0.00000005, or 0.00000000000005 and it will convert into 5e-007 exclusively when you re-open the shader. So, that is the base scale TG wants you to use. Forcing it does not mean it will work... lol
