Liquid in a Glass This is a simple tutorial for Bryce users out there. There are also tutorials of putting liquid in a glass using C4D, 3ds Max and Maya. The process is somewhat similar but for this tutorial in will be an introductory one. Let’s start. Step 1: Let’s create a simple glass using a cylinder. Click on the cylinder icon and size it to suit your need.
Step 2: Make this cylinder positive by clicking the "A" on the little menu located on the upper right corner nest to the cylinder and choosing "positive" from the menu.
Step 3: Next duplicate this cylinder by using the menu's edit/duplicate command or by clicking “CTR + D�. You will now have two cylinders. Make the duplicate smaller than the original by dragging the resize control in the edit tab. Resize again by dragging the top of the resize control to make it extend out of the first cylinder.
Step 4: Now make the 2nd cylinder negative by selecting the "A" and choosing "Negative" from the menu.
Step 5: Using your mouse, drag a marquis around the two cylinders to select them both. Once selected click "G" to group the two cylinders together. If you look in your preview window, you will see that the negative cylinder cut out the positive cylinder to form a glass shape. Step 6: Now it's time to put the materials on your glass. Click the "M" next to the group and select the triangle next to the preview window. Next select the Glass textures by clicking the glass materials in the presets. Now select “moderate glass� material.
Step 7: Now that you have made your glass, it's time to put the liquid in it. So you must select the inside cylinder (the one you last created). How do you do this now that it's inside a group? Easy
just hold your mouse over the cylinder selection control (at the bottom of the screen) and press. Hold the mouse button down until you have a popup appear that lists all the cylinders in your scene. Select the second one.
Step 8: Now that cylinder 2 is selected, click “CTR+ D� to duplicate the cylinder. This will be used to create the liquid. If you remember, the second cylinder was set to "Negative" earlier. This duplicate is an exact replica of that one. For the liquid to show, this new object will need to be a positive so you must now make it positive by using the same method you did before. Select the "A" and then click "Positive" to change this third water cylinder.
Step 9: You will need to resize the liquid so that it isn't all the way to the top, so select the resize control in the edit tab and drag the top of the control to decrease the size of the liquid. Step 10: Now it's time to put a water material on your new cylinder. After all it is water or some other liquid so click the "M" just like you did before. Next select the small triangle next to the preview window. Now select the “Water&Liquids” presets. Now select “Xanades Lake” liquid. Note: The duplicate you created to make the water is part of the boolean group that created the
glass right? This duplicate is also the same size as the negative that cut out the interior of the glass. Boolean operations will cut out a positive object in a group right? So if you render it now, the water will not show. Got to fix that right? So it's necessary to separate the water from the glass then put it back. How do you do this? Several ways, but here is the easiest. Step 11: Select "Cut" from the edit menu. This will cut your water cylinder not only from the scene, but also from the group it's currently in. Now to put it back in exactly the same place with the same material, simply select paste from the edit menu. You can now render your glass. It will contain the liquid you wanted it to have.
