i dont know. it seems i've tried everything but i will keep trying, maybe its my browser or graphics card or something. i will keep modeling and just hope eventually they will go away and i dont have to redo all my models.
thanks

here is an example, this is the famous peabody hotel in downtown memphis with a sign that can be seen throughout downtown. it has so many transparent holes with a "halo" around them it makes it very ugly, i've almost halted progress on anything else until i can figure out if this can be fixed or maybe its even something with my computer.... i looked on another computer without 4.3 it looks fine. thank you so much for your time

just this year i decided to model the downtown city that i live in but i am stuck on this problem- when i upload the model to google earth the edges of the nontransparent pixels are showing a void behind them, other planes and models are not seen though these and it is an eyesore. i just upgraded to 4.3 and they seemed to be acting funnier. i will be happy to figure out how to have clean edges from transparent to nontransparent pixels in google earth.
this is my first post, i am new here and still fairly new to sketchup. i love the idea of building this city im in so any help would be greatly appreciated! thanks
