Re: Asteroid 231937

trappistplanets I embed the two textures in the cmod , so there is no need to add them to the ssc file and this is an odd bug "." in the name should not cause problems and cmodview and celestia use the same base code for rendering ,so there "should" not be a difference Regarding ...

Re: Asteroid 231937

In cmodview, the model was black. When I removed the dots (.), I could see the texture but still not in celestia. odd bug ? the only thing i can think of is your built in graphics chip can not handle 4k textures on a mesh here are 2k versions ( the normal map had to be remade from a 2k height map )...

Re: Celestia 1.7.0 Development Thread

i did enable spice ( -DENABLE_SPICE=ON )
but cmake fails at finding libSpice.so or cspice.a , depending on the spice build

i needed to give the full path including the lib mame
/usr/lib64/libSpice.so



as for gdb that is my next thing to do

Re: Celestia 1.7.0 Development Thread

i just tested your git code ( 1.7 ) and it takes a fair amount of hacking using " ccmake" , the cmake GUI , to get it to build with spice enabled

but it dose finally build on OpenSUSE 15.2

but there are some annoying crashes and it is NOT stable
