There used to be a Blood Splatter pack in freestuff but it looks to be gone now. You could use Anim8or or Wings3D (free modeling apps) and create a blob to you taste and then flatten it. Run it through UVMapper and then apply a red texture and slight reflection. You may want to also adjust the transparancy depending on your scene and lighting. If you have Bryce you can also make a terrain blob and flatten it, texture with red, export it as OBJ and use that. Examples the first method would give: (violence) http://www.renderosity.com/viewed.ez?galleryid=237001 (nudity and violence) http://www.renderosity.com/viewed.ez?galleryid=139051
