Changing to JPG will not save you any graphics memory only some disk space, as the images have to be uncompressed when read, if you want a compressed format that can go to the card compressed use should use the DDS format
You can use many programs to batch resize your textures and convert formats, I tend use ThumbsPlus, for resizing this you will not need to worry about UV's Note texture atlases/composites only work if you're not repeating the texture in any way Gordon Tomlinson System Engineering Consultant Overwatch® An Operating Unit of Textron Systems __________________________________________________________ "WARNING: Documents that can be viewed, printed or retrieved from this E-Mail may contain technical data whose export is restricted by the Arms Export Control Act (Title 22, U.S.C., Sec 2751, et seq,) or the Export Administration Act of 1979, as amended, Title 50, U.S.C., App. 2401 et seq. and which may not be exported, released or disclosed to non-U.S. persons (i.e. persons who are not U.S. citizens or lawful permanent residents ["green card" holders]) inside or outside the United States, without first obtaining an export license. Violations of these export laws are subject to severe civil, criminal and administrative penalties." -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of karl jones Sent: Wednesday, May 25, 2011 3:29 PM To: [email protected] Subject: [osg-users] Merging multiple textures Hi, I have a large number of 3d models(1000's), each model has dozens of textures in bmp format at 1024. I want to try to automate a process that will lower the resolution and merge the textures so I have less textures whilst maintaing the uv coords. Is this possible using OSG? I have seen mention of the Texture Atlas class, is this able to do this? Also is it able to change the texture format to jpeg or dds? ... Thank you!
