nish Well if you read that page it tells you why the programs die.It shows the slippery slope of how a glass puter dies. That's why I posted it. Debby Your suppose to make new alpha forest with the trees you are using right now. There is tutorials here for that. They will match perfectly then cause there the same trees. You render them in the scene you got there so the lighting is the same but you just render the trees nothing else and use those images for the alpha plains. Million tons of spyware running in the background could kill ya too. I've fixed some computers here and have found hundreds of spyware apps running in the background. No wonder why the computer don't work. I know you have open gl turned off. See I use that above program to free up memory before the programs die. It helps lots, but there is also excellent free ones around that do the same thing.
