Light problem: changes when camera is moved
Sep 22nd, 2009, 4:11pm  
Hi,

I'm trying out objloader to get a little ship to fly around a landscape.

Seems to be working out so far except that when I use the camera() function to move the camera around, the lighting changes as if the world is rotating and the light is staying still.

Can anyone take a look at the applet/source (it's still small) and give me some ideas? It's blowing my mind.

Same problem with all types of lighting, OPENGL and P3D btw.

Thanks.

Looks like a good start!  You might be using directional lighting where a combination of ambient and point-source lights would be more appropriate, or you might need to make sure your light code is nested inside your rotations.

fixed it.

watch what options you use when you export obj's, i guess.

in maya, i had to export without normals. processing does the normals for you, right? so it works anyways.
