I have issues with antialiasing in PI using text. The text is created in Photoshop with the smooth option for text. Size is 512 x 128, format PNG, 8 bit, white text on black background. I have tried Greysacale and RGB as Mode, but I am still getting text without antialiasing. Any clues or suugestions? Thanks
Once you create an image for import into pIllusion as a particle shape, there is nothing special about the content -- pIllusion doesn't "know" what the image contains. So there's nothing special about text images.
You don't specify at what point you're seeing the aliased (jagged) image -- so I can only guess what's going on.
It the text is white on black, then import at "regular" not "full-color", and uncheck the "use existing image transparency".
Note that if you import as 512 x 128 and try using that large shape image for small particles, you will probably not get nice-looking text.
If this doesn't help, please provide more details, screengrabs, or send a zipped project file that shows the problem to wondertouch support.
