Poser / DAZ Studio to Bryce Tips

Author: Sray

Tools Needed

  • Poser/DAZ Studio
  • Bryce
  • Photoshop

Introduction

The following tips can be used to correct problems and speed up work flow when using Poser and DAZ content in Bryce.

Even with the uses of DAZ Turbo Imported the problems covered here will still occur.

Step 1 - Correcting Orientation

When Poser or DAZ Studio exports OBJ ( the preferred format for Bryce ) the X and Z axes orientation of the figure is swapped. This makes the figure face backwards and swaps the left and right sides. Bryce has built in tools that can easily correct this problem. On the Edit Tool Palette select the white arrow next to the Resize Tool, then select the Flip X option, then the Flip Z option.

Step 2 - Making Material Families

When mutable object use the same materials, they can be assigned to families so their material attributes can be edited as a single object. This is done by selecting all the designated figure parts, then use the family tools to control the color of their wire frame display. The easiest way to select the figure parts is to hold the Ctrl Key then right click on the figure parts. A sub menu pops up with a list of all the object that are directly under where the cursor was pointed. The figure part can then be selected off of the sub menu. Although only one object can be selected at a time from the menu, mutable objects can be selected by holding the Shift Key each time the menu is brought up, so the object that where previously selected will remain selected.

Once all the figure's parts are selected, the Family Icon is clicked and the parts can be assigned to a color, then a name given to the Family. The wire frame of the selected figure will take on the color of the family to identify that it is part of the family. Then at any time the family can be selected using the Family Selection Tool and Menu located at the right of the Selection Palette. With the family selected the Material Lab can be entered and materials changed or adjusted on the complete figure at any point of the project's progress.

In the Image Example below the dress of Victoria 3 is assigned to a family.

Step 3 - Working in Solo Mode

When new figures are imported into full or nearly completed scenes, object selection can become difficult, due to the many meshes listed on the Mesh Object Selection List and even on the Object Pop Up list. There is a solution to work on only one object or a single group. On the right of the Selection Palette are some VCR type buttons, the middle button is Solo Selection On/Off. This option will hide all the objects in the scene that are not selected when the button is pressed. So to use the Solo Mode Option simply select the objects or groups to be worked on, then hit the Solo Mode Option Button.

Step 4 - Correcting Bump and Trans Maps

Bump and Transparency maps can be made so the alpha automatically loads into the middle window when the map is imported into the Bryce Image Library. Bryce can read alpha channels in image types that support alpha channels, ( like PNG and PDS file types ). The problem is Poser does not use alpha channels, so texture maps made to be used in Poser do not usually have alpha channels.

This example will show how to create an alpha channel for a Poser bump texture map and a Poser transparency texture map, in Photoshop 5.5

Open the bump map in Photoshop. Open the Channel Window ( Window/Show Channels ) if the map is a grayscale there will only be a black channel, right click the black channel and select Duplicate Channel. In the Duplicate Channel dialog, name the new channel Alpha 1. Save the Bump Map as a PNG file. When the PNG is imported into the Bryce library, Bryce will read the Alpha 1 channel and place it into the middle window, which will enable the image to be used in the Bump Material Channel.

Open the Transparency Map in Photoshop, open the Channel Window. If the Transparency Map has RGB channels, convert it to a Gray Scale by going to Image/Mode/Grayscale. ( This can also be done to Bump Maps with RGB Channels ) Then like the Bump Map duplicate the black channel and name it Alpha 1. Save the map as a PNG and it's ready to be imported into the Bryce Image Library with alpha channel to be used in the middle window.

RBG mode images do not always have to be turned into grayscale images. Just one of the RGB channels can be duplicated and named as the Alpha Channel. This way Color Texture Maps can also have an Alpha Channel to use in Bryce.

Step 5 - Facial Problem Areas

There are some facial areas that may need some special attention. Some of the following tips can occur on all Poser Figures and some only occur on Millennium Figures.

Usually for eye lash transparency to look it's best, it is necessary to disable the Cast Shadow Option on the Eye Lash Object. This will clean up the eye area, and bring out the eye lashes. Usually the lack of eye lash shadows is not ever noticed.

Some Millennium Figures have an extra set of eye brows, which can help enhance the eye brow effect in Poser. But in Bryce they can create some problems, like rendering a black residue where the large eye brow meets the for head. This is caused by the large eye brow being slightly embedded into the forehead. When the large eye brow is made transparent it leaves a residue where the forehead and large brow mesh over lap. This problem can be solved by deleting the large eye brow or by moving it forward so it is not embedded into the forehead.

The Millennium Figures have an extra eyeball mesh. It is used to create a glass or liquid effect, it can even be used in Poser 5 as a reflectivity device, by mapping a refection map to it. In Bryce it may be necessary to either delete the extra eye mesh or make it completely transparent. For close up shots, a glass, water of reflective material can be applied to it to make the eye appear wet and reflective.
