Re: Spacecraft for Celestia: Thread 2

looks like there is a issue with the nova-c's UV's
look at the "nova_c_solp.png" it is not rendering
then the black , metal , and gold are stripped

Re: Spacecraft for Celestia: Thread 2

Re: Bugs with textures

if it has a ring then it might be a graphics issue , ie your 3d card/driver

or it might be a issue with your ssc file
