Okay... now that I've (tried, at least! LOL) to cover where to find tabs that you need - onto the toolbar and then the Surfaces tab...
In the above screen shot, you have the Surfaces tab, currently open on the right side. Part of it is seen here, part of it didn't make it into the crop.
Before I get into that, though, look up above the tab... up near the top of the DS window. There is a row of icons that ends with a camera. These are always visible in the interface, as far as I know, at least under the City Limits layout.
So, I'm going to just cover what each icon is, starting from the left and going across to the right.
1.) The first icon, which looks like a square of bricks, toggles keyboard navigation of the scene. This is the
Keyboard Navigation tool. That is what you turn on or off if you want to move around the scene the way you would in a video game. If it's "lit"
(showing as yellow), it's turned on. I guess mine is enabled, though I've never used those keys to move around my scene. With this enabled, you use the W, A, S, D, Q, and E keys to navigate left, forward, right, up, backward, and down in the scene. I, J, K, L, U, and O also allow for some looking around the scene, and the P key will "level" the scene in the viewport. This tool is activated and de-activated by clicking on it.
2.) The next icon is the
Scene Navigator tool. You activate this by clicking on it
(it will turn yellow, or "light up"), and you de-activate it by clicking on one of the other tools in the tool bar. This icon allows for a click-and-drag mouse navigation to rotate the view in the viewport in the same way as a first person video game would do it.
3.) The next icon, the arrow, is your
Node Selection tool. This is a generic tool to click on things in the viewport and get them selected. I also find it helpful to have this tool active when I am posing small body parts, such as fingers or toes or eyes, as it removes the bounding box/arrows and such that the rotate and translation tools have, which can sometimes block your view of what you're posing when the parts are small. This tool is activated by clicking on it, and de-activated by clicking on a different tool in the toolbar.
4.) The next tool is the
Universal manipulator tool. This allows for rotation, translation, and scale directly in the viewport without the need to go into the Parameters tab. This shows how each part of the Universal manipulator is used :
Basically, to use this, you left click on say, the arrow, and hold the mouse button in while dragging it, and the object/body part will translate (arrow), rotate (the small half-circles), or scale (the small boxes) along the axis selected. While dragging, the manipulator tool will disappear. Once you release the mouse button, the manipulator tool will reappear. This tool is selected by clicking on it in the tool box, and de-selected by choosing another tool from the tool bar.
5.) The next icon is the
Rotate tool. This works in the same way as the Universal tool, but affects ONLY the rotations of the selected object or body part. This is selected by clicking on it, and de-selected by choosing another tool from the bar.
6.) The next item is the
Translate tool. This works the same as the previous two tools, except that it affects ONLY the translations of the selected object or body part. Select it by clicking on it, de-select it by clicking on another tool from the toolbar.
7.) The next icon is the
Scale tool. Same as the previous couple of tools, but it affects ONLY the scale of the selected object or body part. Select it by clicking on it, de-select it by choosing another tool.
8.) This next one that looks like a bone is the
Posing tool. I find this tool more trouble than it's worth, so I never use it. But it's somehow supposed to aid with posing figures by click-and-pull/drag with the mouse in the viewport, rather than dial spinning in the Parameters tab. Somehow. I hate it and find it more a hindrance than anything else, so I don't use it. Ever. Select it by clicking on it, de-select it by choosing another tool.
9.) The next icon looks like an "M" in the tool bar. This is the
AniMate tool. I think it's animation specific, which would by why I've never used it, as I don't do animations.
Click on it to select, de-select it by choosing another tool off of the bar, and I have absolutely no idea what it's supposed to do. LOL
10.) This next one is your
Surface Selection tool. This is a big one when you're working on materials in Studio. I use this one a LOT. What this does, is when selected, you use your mouse to click on things inside of the viewport, and it will select those surfaces. To select multiple surfaces at one time, press and hold the CTRL key, and then click on all the surfaces you want to select. Then, when you open your Surfaces tab, whatever changes you make, will be made to all the selected surfaces simultaneously. I love this tool.
Select the tool by clicking on it, de-select it by clicking on a different tool.
11.) The next item, which looks like a human, is the
Region Navigator tool. And now you know all I know about that one.
I've never used it, and have no idea what it actually does. Select by clicking on it, de-select by choosing another tool.
12.) The next icon is the
Joint Editor tool, and has to do with rigging, I would assume. Select it by clicking on it, de-select by choosing another tool.
13.) This next icon is the
Node Weight Brush tool. Again, has to do with rigging, I would gather... but as I've never rigged by hand, I have no idea how it's actually supposed to be used. Same selection/de-selection process as the other tools.
14.) The next icon is the
Geometry Editor tool. This has to do with altering the mesh, I think. Again, I've not delved this far into things myself yet, so I don't know how it's supposed to be used.
15.) This next icon looks like a camera with an arrow cursor in the upper right corner. This is the
Spot Render tool. This is used the same way as you would use the spot render tool inside of Poser. Click and hold the left mouse button, drag to create the selection that you want to render, and release the mouse button to let Studio perform the spot render. Click on the tool to activate it, de-select it by choosing another tool.
16.) The next icon is what you click when you need to alter the settings for the tools. Click on it, and it will open an options box where you can edit the settings for all of the tools on the toolbar.
17.) And the final icon, the camera. This is just your
Render tool. When you have everything set up in your scene and are ready to perform a render, you click the camera icon and the scene will render.
-------------------
The Surface tab will be the next post.
I'm sorry if this seems a little tongue-in-cheek; I'm sure you probably can figure out what the tools are yourself, but I thought it was safest to just run down each tool in order just in case.
