Hi all,

It seems that draging the light directly on top-right corner sphere or using dials, the light could be located and rotated as wish.

How do you adjust the postion and direction of light as you wish?

Thanks in advance

I just grab the dots with the mouse and drag them around, looking at how it affects the figure as I do so. You can also use the dials, for more fine control.  What are you asking? Just how to move them, or is this a survey?

My light sphere is on the left, but you can move any of this stuff anywhere on the screen (even the 'watermark' in the background of some versions..;)

use the parameter dials:

X,Y,Z rotate dials and X,Y,Z trans dials.

for accurate light placement.

If you're using spot lights or point lights, you can also move/rotate them with the usual tools just like any other scene object (move tool, rotate tool, direct manipulation tool).

If you're using the dials to move point or spot lights about, it may be easier to zero all of the parameters out and start from scratch. Try and stick to just two of the translation parameters (X,Y,Z). The lights become more difficult to manipulate if you use all three translation parameter dials.

You can also use Object -> Point At, and make a spotlight point at either a figure bodypart, or some prop - you can have it point at a hidden prop, and then move the prop around to make the light point easier to visualize.

Edit:

Thank you for your reply.

If you're having problems actually selecting a light then you can always do it this way rather than having to find the light manually within the scene.
Once selected, you can move the lights as the others here have stated.

I find the shadow cameras very useful for seeing where the light is pointing. They show you what the light is illuminating as you alter the parameters.
