Hello
Art non-programming related
Osg - ive files
Setup 5 tiled textures used as diffuse colors = 200k
1 large texture used to lightmap scene = 1meg
Problem
Ive file contains imbedded lightmap for each use with diffuse
resulting in large file.
Osg format has each diffuse with same lightmap listed as texture
units. Much smaller as only one copy of lightmap needs to be saved in
'images' folder.
However on loading of .osg the lightmap appears to be recopied into
memory each time it is read in the .osg file, so large amounts of ram
still needed on copies of the same bitmap data.
Question?
How can osg simply reference a texture already in memory, so after the
first loading of the lightmap other textures using it do not reload but
simply reference the already loaded texture.
Thank you Mr. D
