Reading this article got me thinking about the status of VWDs in Morroblivion.
Q1) How extensive are VWDs in vanilla meshes.bsa and what about custom ones for Morroblivion, like RAEVWD for Oblivion?
Also, I read from a post Zilav made that optimized VWDs were made according to the techniques mentioned in the above article for Skyblivion.
Q2) Are those only for vanilla meshes or also for all the RAEVWD meshes?
According to the article, combining meshes and textures for LOD meshes reduces drawcalls. I don't see why it shouldn't be done for standard (non-lod) meshes to reduce drawcalls for them too. But, then some meshes might require 8096 textures.
Q3) What is the max resolution texture the Oblivion engine supports?
Q4) If standard meshes and LOD meshes share the same texture, is there a need to reduce the LOD texture size, since the LOD would use a mipmap of the standard texture... or would they?
