| Summary | 0004557: Bug in vertex shader of mesh grass causes random flashes of geometry to appear every few seconds for a single frame. | ||||
| Description | If you have any mesh grass patches on screen, then random flashes of geometry will appear on screen every few seconds. These are the result of some accumulating rounding errors in line 52 of GrassVertProg.glsl (as of latest develop). | ||||
| Steps To Reproduce | Stare at grass, might take up a few seconds to notice it, but once it is noticed, it cannot be unseen. Impossible to screenshot, as it only distorts for a single frame. | ||||
| Additional Information | Suggested fix (works): GrassVertProg.glsl:52 from return abs( fract( x + 0.5 ) * 2.0 - 1.0 ); to return abs( fract( x + 0.5 ) * 1.99 - 1.0 ); nVidia 560ti, recent drivers, win7 | ||||
