alpha antialiasing Viewport

ayoub44

hello guys
now i'm working on a hand painted environment ; and i'm using some alpha for the plants and grass. so when i'm making the antialiasing of the viewport 8 samples , i get those wierd lines around the models that have opacity map :poly118:



how i fix it ?
thanks you

Looks like the UVs are grabbing color from elsewhere in the texture. Did you try shrinking the UVs a couple pixels?

Or it might just be a bug in Max.

You could try a shader that combines alpha blend (for the texture transparency) with alpha test. You'll need to push the threshold control for the alpha test all the way over, so it only clips the totally-clear parts.

Try what Eric said, it doesn't work, try another shader maybe?

It's also a distance mipping issue, the further away your camera is to the item that is using an Alpha, the more that issue occurs.

I had a character with Eyelashes which had a tiled texture and a hard 1-bit alpha, their eyelashes literally looked like two black cylinders at a distance.

Not sure if it's Max version issue, in 2009 at least, all the shaders have this issue I experienced.

if it's max 2012, you are probably using diretx on the vewport right?
try changing to nitrous and see if that helps

it's not a uv problem ; when i'm running the model with max 2009 , i dont have this problem because 2009 don't have antialiasing for viewport . but when run it on max 2012 and make antialiasing on , the edges pop out
i'm not using any shader , it's just a simple max material

i change the viewport to nitrous but some of the textures are gone , just the flowers and grass textures is showing

here is more pics


max 2012 . Direct3D


here is nitrous mode :
textures gone , when try to reload them but not working



thanks guys for the help

Disable AA. Render a preview 2x the intended size. Scale down in Photoshop. There you go, easy AA!
