You don't need to use ERC. To create the prop you want: 1. Load a poser square prop and reasve it to a pallet as "MinPorp" 2. Open "MinProp.pp2" in a text editor. 3. Delete the two lines near the top that say: storageOffset 0 0.3487 0 objFileGeom 0 0 :Runtime:Geometries:props:square.obj 4. scrole to the end of the file and undernieth "material Preview" delete everything between the curly braces. 5. Do a global search and replace of "propagatingScale" with "scale" (case sensitive). 6. Resave the file. Thats it! The "propagatingScale" or "scale" makes the diffrence between the childern scaling with the parent or not. You can also use the same technique with a minimal figue. This has advantages. When the figure is deleted all the props parented to it will be deleted also. When you resave the figure (with a diffrent name) props parented to it will be saved to the same cr2. You can have the option of scaling all the props at once, or not scaling the props, all within the same minimal figure. Props can suffer from Gimbol Lock, figures dont. So here is how to make a minimal figure: 1. Load a Poser square from the pallet. 2. Open the Hierarchie Editor, select the square and click the "Create New Figure" button. Lets name the figure "MinFig". 3. Delete the square prop from the Poser document and load MinFig. 4. Select the "Body" element of MinFig. 5. Open the "Joint Editor" (its in the Window menu), channge all the numbers to zero (this procedure puts the origin at the base of the BODY). Now select the body part "square_1" fron the dropdown menu at the bottom of the document window and zero these numbers also, then close the joint editor. 6. From the "Object" menu chose "Properties", un-tick (U.S. un-check) all the boxes and click OK. 7. Save MinFig back to the pallet. Thats it! Optionally you can open "MinFig.cr2" in a text editor and strip out the geometry and material refferences, or insert an external object reference, but the amount of geometry in a Poaser square is really quite small, so you can skip this step. Now you can parent your props to the square_1 body part of MinFig, if you scale up square_1 the props will move apart (without rescaling themselves), if you scale it down they will move apart. Note that this applies to scaling "square_1", if you scale the "Body" element the props will scale with it. If you don't like this behavior of the props scaling with the Body element, open MinFig in a text editor and do a global search and replace of "propagatingScale" with "scale", that will fix it. I think I will post some examples of minimal figures to the free stuff, but it may take me a day or two to get round to it.
