Tourguide or walktrough animation

[Roland Melkert]

i will need explained further...
Step 4. and Step 7.

4: Open the windows file explorer and using the mouse drag the .lua file onto the LDCad program window while your model is open in it.
7: In the top menu bar their is a 'scripting' item inside it is an item with the name of the current open file, inside that item their is an item "Minifig tour". Use that to start the animation.

Also i dont quite understand what you are saying here

A 150 thousand part model might not be able to animate in realtime (at 25fps), you would need to lower the frame rate or export it to a collection of png files which you can combine into a movie using a video editor.
