Modifying the opacity of the forst loaded change only its luminosity (or alpha).<br><br><br clear="all">Cordialement,<br><br>-- Mathieu PICCIN<div><div></div><div class="h5"><br><br><br>

Hi,<br>
<br>
In my rendering view I would like to show imagedata and additionally some information using transparent glyphs. But not all glyphs have the same transparency. So I change the color and alpha settings for each cell of the glyphs seperately. Unfortunately now I cannot see the volume behind the transparent polydata. Does anybody know how to solve this problem?<br>
<br>
Thanks,<br>
Martin<br>
