Hello forums,

I just finally learned how to lay UV coordinates correctly and assign textures to models. I will be offering a free model pack soon. I have a question in return. When modeling in low poly why do my models appear triangular when I render them? Images are below;

Here's the non-textured version. As you can see it appears triangular.


Here's the textured version. The texture is not finished yet.


I wonder what could be wrong.

Typically because smooth surfaces have a lot of polys. I use Mudbox a far amount and if you take a sphere, for example, and reduce the poly count, you will start to see the edges on the sphere. Real-time, low poly modeling is an advanced art form and in some ways harder than realistic, cinematic modeling.

BTW, I've lived in Maitland/Winter Park my whole life!

This is one of the first low poly models I have ever made. It doesn't look terrible. The triangulation is bothering me... Any ideas on how I can get rid of the triangulation while keeping it between between 40 to 100 polys? I attached the blend file.

haha I just moved down about a year ago to attend Full Sail University. Winter Park is awesome!

you need to assign smoothing groups to your model.i have no idea how to do it in blender but im sure one of the other guys will be able to help you out.

I know I could use a subsurf modifier on it or use the smoothing option in Blender. I don't think the smoothing option carries over to game engines though?

it should do.i use it all the time on my models but maybe blender is different ?

Yeah subsurf up the poly count by alot.

Smoothing option does apply to game engines when you export the models?

Now it looks all rubbery.

Wow henry, that was really fast! Thank you!

I think I must have modeled my chipbag wrong or something... Your wireframe is completely different than mine.



If I'm correct, you turned on Smooth Shading?

there is no right or wrong way to model only your way

its just a box with a few of the verts moved about so it only took a few minutes

Quote: "If I'm correct, you turned on Smooth Shading?"


its called smoothing groups in max i just gave the front & back faces 2 different groups that stops the black edges that you got on your model

Yeah, everyone has their own way of modeling. =P Your crisp bag looks professional for low poly. It seemed really fast for me because it takes me awhile to texture a model.

This is the only thing I see in Blender that is relevant to the smoothing groups.



I Googled "Blender Smoothing Groups" but I cannot find anything on it. I know what the smoothing groups are in 3DS max but I can't find them in Blender.

I'm struggling with this problem now, having my first serious attempts at modeling for my DBpro games.

My current work flow is;

By trade, I know Inventor... so naturally I'm using it to model. But I'm an absolute n00b when it comes to anything outside my parametric world (and it's a good(!) parametric world too!).

Create and colour my model in Autodesk Inventor. Import my .IPT file into 3DsMAX, save as a .3DS file. Import the .3DS file into Wings3D, toggle the colours, export the model as a .X file.

The reason I'm not exporting a .X file directly from 3DSmax is that the Panda .X exporter is no longer compatible with the 2013 release, and I also wanted to learn a simpler free modeler, such as Wings3D or Blender, since they're so popular.

If someone's keen to help, let me know what format I should upload the file as.
