I recently saw an example of a sculpt that appears to have 50 rectangular plates with two stacks of 25 plates beside each other. Each plate appears to be connected to the one below it, but I can't see any connecting lines connecting the two stacks in edit mode. When I try to make the same thing, the most I can get is 10 plates in one stack using a cylinder mesh in Blender. Can anyone tell me how this is done and what program can do this?

Try checking this thread out: /8/b0/295541/1.htmlThe method used is called 'oblong sculpts', because the sculpt map is literally an oblong rectangle, rather than a square. It allows you to increase detail in one axis while decreasing in another... for instance, you could create a 64-piece object, but it might be limited to having a rectangular shape, rather than rounded at all. Working with oblongs can be rewarding, but be forewarned, texturing them can be a bitch. As for which programs are capable of it... most 3d modellers that support SL sculpt export, I believe.. Blender included, for certain.

Thanks Keira  I also found a website that has some info on oblongs with Blender too, however I can't seem to get them to display correctly /8/b0/295541/1.html

I've posted a blend file example of this technique here: http://dominodesigns.info/node/89I only went for 16 blocks so that it'd be resistant to a level of LOD change, but it's shows the cleanest way to handle this technique. Basically I cleaned up and copied a 4 x faces, 3 y faces sphere mesh along the UV Map leaving a gap of two faces (for 2 LOD levels) between each. This let's you model without the connecting lines as the baker will fill in the gaps. Just make sure the edge of each gap is drawn to a single point on the mesh.

I found if you go into "advanced/debug settings/rendervolumeLODfactor" and raise the value to 4-8 this will help with LOD and the sculpts will not bork even if you zoom quite far away. I don't notice and additional lag. I found out SculptySpace and the test view do not support oblongs. No wonder I was having problems with oblongs displaying correctly..I'll have to upload them into 1.23.4 and hopefully all will be well.

I don't notice and additional lag. Just remember, that these settings are local to your viewer. So only you will be able to see your artwork as you designed it  Others with "standard settings" will still see the unpleasant LOD-effects. Maybe better try to optimize for LOD iinstead of relying on the viewer settings ?
