New to Daz Studio but have been using Poser since V2. 

• Just installed Victoria 4.2 and Muscle Maps for her. The figure is working fine, But I do not find the Muscle maps. I do find the maps in the content on hard dive.
• Where are they? And and how to apply them to the figure?

Couple other questions

• How to see effects of morphs in real time?
• How do you conform on figure object to another?
• Can you assign custom hot keys for navigation pan, zoom & rotate?

The Muscle maps should tell you which folder to look in in the readme - the DAZ Studio presets, which will give better results than the Poser Mat poses, are in PeopleVictoria 4TexturesMuscle Maps in the folder you nstalled to. You can apply them either through the Content palette or through File>Merge....

What do you mean, see the effcts of morphs in real time? Morphs should show as you apply them - they are set through the Parameter palette (View>Tabs>Parameters).

Select a clothing figure (the root, either click the line with the item name in the Scene palette or double-click on any part of it in the Viewport) and in the Parameter palette there should be a button labelled Fit which when clicked will give you a list of all the figures in the scene from which you pick the Conform target as you would in Poser. You can also right-click on part of the clothing and select Fit to... to get a dialogue very like the Poser conform to dialogue.

You can set hot keys in Edit>Customise - the camera controls are at the lower left, pick the action then double-click the currently listed shortcut and hold the modifiers you want to use,

Just wondering... will these muscle maps only show in the render result or before while I am still posing and all? I am having a little problem with maps for M4, this is why I am asking. :-)

The muscle maps will show in the preview - they replace the skin texture with a texture showing the muscle groups - though you won't see the full effect until you render. Michael 4 has a set of displacement maps to bring out fine detail that isn't in the mesh, and those add to the existing textures and won't show until you perform a software/3delight render.
