Hello all,

What is the difference between a "Real" clip texture and a "Virtual"
clip texture?

Reading the man pages, pfClipTexture, it says that the system limitation
is 32K x 32k. I have seen in other locations a reference to Virtual
ClipTextures which states they can be as large as 4M x 4M.

Does this mean I can set the virtual size in the ct file to 4M x 4M and
have an image cache file (s) ( for all of the mipmaps) to handle a 4M x
4M virtual clip texture? I am assuming if it can handle a 4M x 4M
virtaul cliptexture the "real" cliptexture is the tile size which has a
limitation of 32K x 32k for 64M of texture memory, is that correct?

Thanks,
Scott Brabson
