View Full Version : Radiosity, fixed sampling?

Some more attention may be nice, hopefully someone from NT notices this and can let me know if this is possible:

1: Make random scene, turn off all lights ,turn on background color, turn down GI to lowest settings. F9 gives attached example scene.

2: F9, gives different GI solution. Splotches moved.

3: F9, moved again.

4: Set render threads to 1

5: F9 and another F9. These 2 frames are 100% identical.

For a great GI comp trick to work ( http://www.spot3d.com/vray/help/150R1/tutorials_anim.htm ) it would be necessary to have the GI solution stable per frame, like it is for 1 threaded renders.

Is this possible to implement as a radiosity flag perhaps, it would be very helpfull for a variety of animated Gi scenes.

update: tried Modo's interpolation solution and it is fixed per frame too..
