Re: IDEA: Support for one of the formats supported by Windows Paint 3D

My question is: can Celestia implement support for one of these formats (at least .obj due to versatility) natively for celestial bodies/spacecraft?

obj files have been supported for many many many years

Re: How to create a bump map with wilbur ?

keep in mind that wilburs erode function ASSUMES the map to be in Mercator projection and hence the poles WILL be messed up
