So you can only aim for rendering. Your script line is basically OK. You can find more examples in bitmap trees and bitmap people in the ArchiCAD Library.<BR /> <BR /> Regards, Fri, 04 Dec 2009 16:45:38 GMT ztaskai 2009-12-04T16:45:38Z https://community.graphisoft.com/t5/Libraries-objects/Alpha-Channels/m-p/151491#M23461 <DIV class="actalk-migrated-content"><R>Hi,<BR /> I'm having trouble gettting an alpha channel to show up. I sit possible for a PICTURE to use its alpha in both the internal engine and openGL, and also Lightworks?<BR /> <BR /> I'm currently using <PRE>PICTURE 'FE_sign_border_a.tif', 0.6, 0.15, 1+0 </PRE> which does the job fine for Lightworks, but doesn't show up in the working 3D views.<BR /> <BR /> I've managed to make materials in the Materials Settings window that include alpha channels that work in the Internal Engine (but not OpenGL) - how would I do this in GDL?<BR /> <BR /> Any help appreciated!<BR /> <BR /> Thanks,<BR /> <BR /> Derek</R></DIV> Wed, 24 May 2023 09:55:31 GMT https://community.graphisoft.com/t5/Libraries-objects/Alpha-Channels/m-p/151491#M23461 derekjackson 2023-05-24T09:55:31Z https://community.graphisoft.com/t5/Libraries-objects/Alpha-Channels/m-p/151492#M23462 Unfortunately, the OpenGL implementation of ArchiCAD doesn't include a full alpha channel support.
