This tutorial is going to help the ones who are new to Bryce to loose their fears when it comes to position the moon on a right spot without having to use the little trackball.

Step 1 - Setting up the scene
After you have opened Bryce, you need to set up the scene and the objects you want to use, for this tutorial, I made this gate, how I made it? Well, that's another tutorial, and I am using the Director's View in this case.

Now let's go back to the scene, set your camera to "Eye Level Camera" and drag the scene a bit down as shown on the image below.

To drag the scene, you need to use the little hand that you see in the green circle.

Step 2 - Opening the Sky Lab
Now we are going to open the Sky Lab, it is the little cloud with the little rainbow like indicates the image below.

Once at the Sky Lab, you will see that it appears just the sky, the little down arrow under the sky images gives you the option of "Render in Scene" and "Render Against Neutral", you need to choose "Render In Scene" because you can take a better look at what you are doing.

Step 3 - Going from Day to Night and the Full Moon
Now, you need to change the day for the night, so, click on the little sun like the image below shows, and don't be afraid of not seeing the moon yet, she will come in a minute.

To position the moon on the right spot, go to where the Azimuth and Altitude are and set these numbers

Azimuth: 180

Altitude: -17

Just like the image above indicates, and there was the moon!
Step 4 - Let's "dress" the moon.
You probably notice that the moon looks with that little blue line around it, that is because there is no moon image set up yet.

Go to where it says Moon Fase, and click on the little dot there, it activates it, then drag the moon image under the dot that it already turned orage when you had it activated until you see the full moon, also click where it says "Moon Image" and place the Earthshine and Softness according to your taste, I did make like:

Earthshine: 100

Softness: 1

Then go to the Sun/Moon size, turn it on, and select the size you want, I used the default for this tutorial.

The image below shows you how to set these controls.

Step 5 - Changing the Sky mood
Now, that you have the moon positioned where you want it to be, I decided I wanted the moon to be right in the center of the gate, so, it will stay there, and, it is time to play with the sky a bit, just use Sky and Fog controls and set up the colors you want, this case, is your choice of colors, the image displayed here is just a sample.

And you are done, just render your image and see if you like it.
Step 6 - Final words.
When entering the moon position using numerical values, and using the Director's View, keep in mind this:

1- On the Azimuth, numbers bigger than 180 will move the moon to the right, numbers smaller than 180 will move it to the left.

2- On the Altitude, the smaller the number (we are working with negative numbers for this one), the higher the moon will show on the scene.

An example:

The image below shows a variation, noticed that the moon has moved to the right and it is a bit higher.

In that case, I set up the Azimuth at 182 and the Altitude to -20.

This other variation, I changed the moon back to Azimuth 180 and the Altitude to -5

I hope this tutorial helped you, and that the problems of setting up the Moon on the desired spot is already over.

Postioning the sun and moon in Bryce

Author: rgagnon Printable Version
Step 1: Double Click the sun position sphere
Step 2: Click the sun into place inside the work area
Step 3: Placing the moon
Tools Needed
* Bryce 5


Every now and then, there is a reason to precisely add the sun or the moon into a Bryce scene, but there is no easy way to normally do this other than to patiently rotate the sun with the sun position sphere on the Sky & Fog Palette. An undocumented feature in Bryce provides a much nicer point and click method to get the sun where it's wanted.

Step 1 - Double Click the sun position sphere
Go to the Sky & Fog Palette and press Ctrl & Alt together and double click the sun position sphere. This is a hidden keycode that now permits precisely placing the sun.
Step 2 - Click the sun into place inside the work area
Holding down Ctrl & Alt together again, click anywhere above the horizon line and an asterisk will be placed in the main work area to show where the sun will be seen in the rendered image. The nano preview screen will more dramatically depict the sun's effects on the Bryce scene.
Step 3 - Placing the moon

The sun can be changed into the moon by either clicking the day/night menu toggle or by clicking in the scene by holding down Ctrl-Alt-Shift. That's all there is to precisely positioning the sun or moon in an image. This is a nice feature to create sunsets and spooky images with a full or partial moon.





Setting Sun &Moon

Step 1: Flat and Lifeless
Step 2: Display Mode
Step 3: Sun Sphere
Step 4: Setting position
Step 5:  
Tools Needed
* Bryce 5

Render looking dull or a bit lifeless, need to place the sun or the moon at a certain point of the image to achieve the correct look, read on...

Step 1 - Flat and Lifeless
Here we have the scene set up with a standard preset Bryce sky, looks wrong and using the sun postion trackball is causing migraines.
Step 2 - Display Mode
Switch the display mode to mixed wireframe/render or pure wireframe mode using the "wireframe cube" by the side of the image window. The position of the sun/moon appears as a star * .
Step 3 - Sun Sphere
Select the Sky & Fog Palette and then hold down ctrl+alt and double click the sky sphere.
Step 4 - Setting position
Hold down ctrl+alt and click into your scene view to place the sun at the cursor position, or use ctrl+alt+shift to place the moon. If the sun is already on screen this will repostion it.
Step 5 -
The sun is shown as a yellow star, the moon is now shown as a blue wire star. Play around until you achieve your desired result, alter disk size and glow etc. to fine tune your image.
