IIRC while playing around with the environment mode for [pix_texture] (sending an [env $mode( to inlet 1), GL_Blend or GL_Add (2 or 3) made the square visible without the texture. > - if it is not supported, try manually setting the texture-coordinates > to 1,1 (e.g. use [pix_coordinate]) (you could also manually set the > texcoords by modifying the messages that comes out of [pix_texture]; > it is human-readable and of the form (iirc): " > "; you want to modify and ) I'll try that when I have my hand on the Vista machine again.

"not working" is a rather vague description. i recently discovered that the output of the 1st pix-texture would give wrong texture coordinates when using normalized textures (power-of-two sized). the w32-binaries certainly still have this bug. for now i can think of two workarounds: - if your machine/build supports it, try using rectangle-textures and see if it works. - if it is not supported, try manually setting the texture-coordinates to 1,1 (e.g. use [pix_coordinate]) (you could also manually set the texcoords by modifying the messages that comes out of [pix_texture]; it is human-readable and of the form (iirc): " "; you want to modify and ) mfa.dr IOhannes This message was sent using IMP, the Internet Messaging Program. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Why are there two gemheads and pix_textures? Does it work if the second gemhead and pix_texture objects are removed? ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
