I have water surface animated with blender generated clouds as normal map on a simple plane. Only Z-Offset of the texture is animated. Everything is OK except 5 or 6 frames (inconsistent), when the water surface jumps up. Theese frames appear randomly, when I tune the settings of the texture.
Thanks a lot!
*In the attachments yo can find two frames of seq. If you place them near each other, the bug is noticeable.
Anf I also attached my texture settings. (Only Z-Offset is animated).
