I'm currently working on a sports complex and I'm need of baseball players to be shown in my rendering.
Any suggestions how or where I can get these from?
I'd suggest you look at creating your own figures using Poser or Daz Studio. If you truly want custom people content for you renderings, they are a must.
I use Poser Pro for figure content. You can export the figures as a 3DS or OBJ format which will include material mapping, or as FBX which will include texture mapping as well as any movement (walks, etc.). hey can be imported into either Microstation or Lumen RT. Surface Fidelity allows you to adjust the complexity of the exported mesh. You can merge the figure, clothing and props into a single mesh which simplifies the resulting geometry. Poser will also import Daz content.
