View Full Version : images size for textures

05 May 2003, 08:56 AM
I took a image file of a soccerball to use with the bump, it is jpg, I know it's not the ideal. What happens is that I create a sphere(default parameters) and apply the bump(projection sphere), everything is ok, but if I scale down the sphere, the bump looks deeper and starts to distort, and if I scale up the bump starts to desapear. How can I avoid that????
Is there an ideal resolution to textures or depends of the surface I'll apply???? And what's better, tga, tiff or what????

Thank you people.:drool:

I think you need to delete the history of your shpere so that the spherical projection turns into 'set' UV's. At the moment you are scaling your sphere but your spherical projection manip/icon is staying the same size.

There's no "ideal" size for textures, it all depends on how large the objects will appear in your rendered image - small background objects can get away with 256x256 textures, whereas foreground objects should probably just start at 1024x1024...

Also, I'd recommend not using .jpg, since it's a lossy format and doesn't support alpha channels; .tiff or .tga is usually the way to go!
