mipmap HDR?

[sharktacos]

Assuming that one is converting texture files to mipmap, would it be advisable to also convert EXR files (used for IBL) to mipmap as well? Are there any problems with using mipmapped files for IBL (via a dome light)? What about EXR files used as displacement maps, being converted to mipmaps? Any issue there?

Note that I am assuming that when converting an EXR to mipmap it will remain in EXR format, linear, 16bit half, DWAB compression.

There should be no problems if you generate mipmaps. It is also good if you can generate tile exr or tiff/tex/tx files.
It will help memory consumption if you use tex/tiff/tx files for textures that do not require the higher precision of exr files (16 or 32bit).
For example many people that deal with tons of textures use tx/tex/tiff for the diffuse textures.
