Well, I made a terrain with triangle strips. Some strips can overlap each other, so the corners of the textures are black to have transparency. Problem: where the corners of the transparent textures meet, I have ugly seams with ugly colors: First I was using: GL_SCR_COLOR,GL_ONE for blending It gave me an ugly color and seams. Then I used: GL_ONE, GL_ONE This give me ugly seams and another ugly color where ends meet? Is this normal? Thanks, RenRan

I'm not sure it will give enough information for the solution to your problem, but images would help.

Yes, the images would help a lot, cause it could be z-fighting that you call seams or something else, but we don't see so we can't tell...

you need to upload it to imageshack.us or such and post a link here, on imageshack you'll get a tag you can post immediately (it's the "site" one, I think)

Hey i don't know how long you have been using openGL, but i will tell you what caused a similar problem for me when doing particle systems,
have you disabled GL_DEPTH_TEST before drawing the polys and re-enabled it after?
Because without doing that you will be able to see the edges of every poly and leads to a very ugly look, it could be something this simple if you are new, or something i don't know about but good luck and i hope it is this easy :P .

Hey Deftoned, it's better but because You can zoom in very close, the seams
are still visible.
I did try a lot and only Java's blendinspect could help me.
But I think that seams will always be visible unfortunately.

Anyway Thanks,

RenRan
