I have a question about 3d modeling.

I have ZERO experience in 3d imaging, modeling....none!

However, what I'd like to know (if possible) is how difficult is it to take a pre-existing 3d model and reduce the poly count?

I'm using a little Steam game called Table Top Simulator and it can allow only certain size of OBJ files. Most 3d models I see online are quite large and I'd like to reduce those images for personal use.


Hopefully the link here shows exactly what I'm trying to accomplish. This person has themselves found online 3d models from various sites and reduced the poly count using 3D Studio Max.

I've heard Blender is more user friendly?

Anyways, if someone can push me in the right direction on how to reduced existing 3d models I would greatly appreciate it. I know this isn't a simple "follow this one tutorial and you're done", but I'd like to know what I'm getting myself into before I jump in (this is for personal game use only and nothing something I'm devoting a lot of time to....but, I do find the urge to learn much!)

Thanks to anyone that can help.


Another way to reduce vertex count is by sculpting out the excessive geometry.
note the low strength and the detailing mode set to collapse edges.

  • $\begingroup$ Can you take a 2D cutout image and make it more 3D? If so, would this be easier to learn than reducing the poly count of an existing 3D model? $\endgroup$ – Acctingman May 31 '16 at 21:28
  • $\begingroup$ @Arcctingman Are you going to animate it? you can import an image as a plane and give it some thickness, you can even cast realistic shadows if the picture have transparency. Instead of reducing the poly count you could just learn how to retopologize the high poly mesh, especially if you will texture/rig and animate it later. $\endgroup$ – user2816 May 31 '16 at 21:58
  • $\begingroup$ Not looking to animate anything. I just want a 3d looking model sitting on a clickable base (like in the Steam link I provided). I'm not sure what will be easier for me to take on.....making a 2d image as 3d as I can, or reducing the polycount on existing 3d models (the Steam game I'm using cannot take large polycount models)....thanks R00t $\endgroup$ – Acctingman May 31 '16 at 22:14
  • $\begingroup$ reducing the poly count is easier, use the Decimation modifier that Danyl suggested in his answer. $\endgroup$ – user2816 May 31 '16 at 22:25
  • $\begingroup$ After looking at a couple video tutorials on making a 2d image 3d, I think you're right :) Thank you! $\endgroup$ – Acctingman May 31 '16 at 22:46
