ulf.schroeter Posted September 29, 2010 Posted September 29, 2010 Problem When starting UNIGINE sometimes random screen geometry appears on the screen with random/streched texturing showing most propably parts of some renderbuffer content which animates when changing the view. Geometry itself seems to be random, somtimes 1/2 triangles like in the sample screenshot, sometimes 1/2 degenerated triangles showing up as a thin line and sometimes a quad covering a complete lower/upper/left/right quarter of the screen. At least one geometry vertex seems to be located always on screen center position. Problem shows up randomly on different PC's running XP/DX9 with latest NVidia drivers. Problem already started to appear several releases before last one. Sometimes geometry disappears after restart or resolution change, sometime not. Quite strange...
cizi.kim Posted September 29, 2010 Posted September 29, 2010 I have often seen this bug in my project which is running on XP/DX9. but it seems that the problem don't occur in OpenGL mode.
steve.brodie Posted September 29, 2010 Posted September 29, 2010 I have seen that issue once or twice, and it only occurs on a few graphic cards (one ATI card we had in particular) but was fine on other cards.
alex.dovgodko Posted September 30, 2010 Posted September 30, 2010 I have seen that issue once or twice, and it only occurs on a few graphic cards (one ATI card we had in particular) but was fine on other cards. We already reported this bug in tech support. We see it often on NVidia 8600GT and ATI HD2600PRO. Waiting for fix desperately as restart of the game doesn't cure this illness.
ulf.schroeter Posted September 30, 2010 Author Posted September 30, 2010 Just for illustration an example of quad geometry situation. Color changes randomly on camera moves or scenery animation.
ulf.schroeter Posted October 25, 2010 Author Posted October 25, 2010 All problems under Direct3D9 is solved. Very nice, what was cause of the problem ? We searched for it, but couldn't find it.
frustum Posted October 26, 2010 Posted October 26, 2010 Very nice, what was cause of the problem ? We searched for it, but couldn't find it. engine/render/direct3d9/framework/D3D9Ffp::render_screen() function was called with wrong number of primitives 3 instead of 1.
