Too many polygons?

Hello, I'm trying to be a prop modeler.

I recently made a plate ( I know, a rather simple asset). Anyhow, after I was done with it, I noticed I had 256 polygons on it. Is that too much for such a simple asset?

Hi there,

1. What software are you using?

2. Are you making props for Film or Games?

I don't modelling for games, but I everyday modeling for stills rendering and for simple assets often I have more than 2000 faces. Especially when I use subsurf modifier. So I think that 256 isnt too much. But better will be if some game modelers will say something.

When modeling for games you want to be efficient with your polygon count - how many you can get away with will depend on the target system, mobile obviously requiring more optimization - but just asking if the number is right will only get you into the ballpark.

Instead, I would suggest you ask yourself for every single polygon, "Does this help define the form of the object I'm created or not?". On top of that, you'll want to consider the visual importance of the object. How big will it be on screen? Will it be close to the camera or far? etc...

These questions will help you to figure out how many polygons is acceptable. That same plate could be created with 8 triangles, details faked in the texture, if it's just a part of the background... but maybe it needs to be 256 polygons because it's a key asset with a lot of closeups.

To answer your question, 256 sounds a little high... but without the context to define the detail needed, I can't really say for sure.

For games, theres no exact answer, it depends what the artist is going to do with the model. As a general item in a scene though; eg. say your character walks into a house in a game and the plate isnt an important item in any way, then yes 256 polys for a plate is way too much.

QFT. There's no right answer based on the info given. There was a time when plates were just a texture painted into the tablecloth (I imagine some mobile developer somewhere is doing that very thing right now).

If you want to be a game artist, I'm pretty sure these guys can answer your question: http://www.polycount.com/forum/

I'm not a game modeler, but I've heard that in-game character models are around 40,000 polygons nowadays. Maybe that helps.

Hey i'm gonna bump this again.

again, I'm in blender i'm still attempting to make a ceramic cup.

I noticed in my cup i'm making that whenever i'm out of edit mode I have 225 faces. yet, when i'm in edit mode It say i have 96 faces/polygons.

Why is that? I have the solidify modifier, but too my understand that shouldn't have increase my poly count.

solidify modifier increases poly count.
If you have simple triangle face - then you have one face without thickness. If you add solidify modifier - then thickness produces another four faces and from one face - you get five faces.

I'm not trying to say you are wrong. But If i'm understanding this correctly, if i have 4 faces, and add solidify which adds an additional 4 faces on each face, I should have on my cup (which has 96 polys) it should have 376, But it has 226 when in object mode.

Depends on how it's used in the game. I would say that a simple background prop like a plate should probably be around 100-150. If you feel like you can still reduce it without screwing up the shape and the silhouette, then the poly count is probably too high.

Not if those original 4 faces are joined together. Add a plane, subdivide twice and add a solidify modifier. Count no. of face before and after applying the modifier. 16 faces increases to 48 faces

Count of faces added by solidify modifier depends of shape of original object. For 4 faces this can be tetrahedron solid - and then will be added only 4 new faces. Object can be also 4 not connected flat quad faces - and then solidify will add 20 new faces.
