<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">Hello<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Playing with the gl objects in GEM (0.90) on OS X (Pd 0.38-4 Extended, via Hans) , ive noticed that GEMglClearColor has 5 inputs, one for the gem render chain, 2 - r, 3 - g, 4 - b and presumably 5 - alpha, yet, changing alpha results in no change in the window Changing the RGB values does, just like [color] to gemwin (as it should).</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Presumably, changing the alpha would act to let the scene draw 'over' itself, and give an easy way to do trails/blurring. Jitter supports this feature (not griping.. just saying :), any chance , or workaround to get similar functionality, as I love the aesthetic of it. Id rather not use snap2pix/snap2tex.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Thanks,<BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#D30000" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;; color: rgb(211, 0, 0); "><B style="color: rgb(211, 0, 0); font-size: 10px; font-weight: bold; "><BR class="khtml-block-placeholder"></B></SPAN></FONT></DIV><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#D30000" size="1" style="font-size: 10px; ; color: rgb(211, 0, 0); "><B style="color: rgb(211, 0, 0); font-size: 10px; font-weight: bold; "><SPAN class="Apple-style-span" style="color: rgb(211, 0, 0); font-size: 10px; font-weight: bold; ">v a d e //</SPAN></B></FONT></DIV><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#7F7F7F" size="1" style="font-size: 10px; ; color: rgb(127, 127, 127); "><B style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "><BR class="khtml-block-placeholder"></B></FONT></DIV><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#7F7F7F" size="1" style="font-size: 10px; ; color: rgb(127, 127, 127); "><B style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "><SPAN class="Apple-style-span" style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "><A href="http://homepage.mac.com/doktorp/">http://homepage.mac.com/doktorp/</A></SPAN></B></FONT></DIV><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#7F7F7F" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;; color: rgb(127, 127, 127); "><B style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "><SPAN class="Apple-style-span" style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "><A href="mailto:doktorp@mac.com">doktorp@mac.com</A></SPAN></B></SPAN></FONT></DIV><DIV style="font-size: 13px; "><FONT class="Apple-style-span" color="#7F7F7F" size="2"><SPAN class="Apple-style-span" style="font-size: 10px;; color: rgb(127, 127, 127); "><B style="color: rgb(127, 127, 127); font-size: 10px; font-weight: bold; "></B></SPAN></FONT></DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></DIV></BODY></HTML>
