3D WORKSHOP:
Baking Light Projection And Shadows
18
If you need to change your light properties (location, color, ….) you will have to bake again as we just did. Press New Image and 1024 for image size. 512 would also be fine. It's important to select “New Image” ONLY the first time we are doing this calculation. If we need to calculate the UV’s again deselect this option. Ok. We have a new Black coloured texture for our cube and the UV coordinates. Exit edit mode. Press F10 to go to render options and go to “Bake” menu.

You can animate your camera inside the room by changing the UV/Image window to the Ipo Curve editor. Go to frame 1, select the camera, press (I key), and select LocRot to make the first key.

Select our cube if not selected, press the “Bake” button and voilà! We got a nice, shadowed room!. The baked texture must be saved. If you save your scene and quit, you will lose the bake, so in the UV editor, select image-> save, or pack to include the image in the .blend file. You can improve your shadow quality by selecting the light, hit F5(Shading) And increasing Soft size, samples and threshold.
Advance about 100 frames. With the camera selected, press (Shift + F) “fly mode”, use the W,A,S, and D keys to move your camera, and click the LMB when you are satisfied with the view. Press (I key) and select LocRot again. Insert as many keys as you like... once you are finished, hit F4 to go to the Logic Panel. Add a sensor, controller and actuator and set up like this (Camera selected) Ok that's all… oh, and press P to preview. :P
