What I put in MyWonderfulMaterial.zip ?
Usually a material has at least 2 textures (colour, bump).
Usually this texture aren't littler than 800 x 600.
Let's say we use (at worst) a map 1024 x 768.
Saving as uncompressed Tiff, 8bit, we get an image of 2,28 MB (2.392.064 byte).
Plus, there is the standard scene preview (500 x 500 -> Png, 320 KB). It has beed requested more times to include this preview in the zip to have a preview while browsing with explorer.
And there is the MyWonderfulMaterial.mxm (117Kb, compressed about 90Kb).
Total is about 4,98Mb.
I can compress it a little using "Ultra" compression but i reached quite soon the limit.
If I have 16bit texture the space needed for one tiff became double.
Normally I don't reach the 5Mb limit, but i think 8-10Mb can increase the quality of the map you can upload (specially for people who can't host hy-res texture elsewhere).
Thank you,
Ricky.
Ps. using LZW lossless compression or Png I increase the 1024 x 768 limit.
But photographic images (with a lot of details) make compressions - LZW for Tiff and deflating for PNG images - less efficient.
