[Bf-committers] opengl rendering

Sun Oct 2 18:01:19 CEST 2005

Ok,
I've been talking to eyecandy and he asked if the ogl render using the 3d
view or the camera view (as in regular internal blender); checking this
showed that the render is of the 3d view, always, meaning it is not rendered
"as if" it is blender internal.

So, the issues are (by order of importance):
1. ogl render does not render from camera view point
2. sequence preview fails

also, batch rendering does not work, but it's not meant to work with ogl,
