alpha map outline transparency

snake85027

I have a basic .png file that has a white square in the alpha channel to so that all i can see is the color from the layer thats also just a square. When i put it on a plane within max for some odd reason its adding a semi transparent outline around it and inside the alpha channel there is no outline around the alpha channel to cause this. Here is an example.


here is what it looks like inside of torque


I tried contracting the selection in the alpha channel and seeing what that would do but i still get that semitransparent outline.

i started off with a transparent file. Just made a simple square selection and filled it with blue and made the alpha map white using that same selection.

I went back and made it all just one color and left the alpha map the same and still within max view port it makes the edges transparent.

Could be you have Image Alpha on in the Diffuse slot, which causes the Diffuse bitmap to mix its colors with the Diffuse color. If so, either change the Diffuse bitmap's Alpha Source to "None {Opaque)" or set the Diffuse color to black.

Or... could be this.

thanks for that, i ended up having to change some code in torque to get it to work.

Man, we're such alpha n00bs.
