Regarding limit of triangles on a Blender mesh

crashedthe911 · September 25, 2019, 12:16pm

Hello, yesterday I attempted to make a pet on Blender. Although I did make the pet, I went across some problems! I think we’re all aware that Roblox only allows 10k triangles per mesh. After I made the mesh, which by the way I used Subdivision Surface, I realized I had 700k+ triangles. So I turned the view of the Subdivision Surface down. Then, my mesh started to get a lot of faces, meaning it wasn’t smooth as it’s supposed to be.

What I wanted it to look like:

What happened on Roblox:

As previously mentioned, if I turn down the view on Subdivision Surface it looks like this: https://gyazo.com/b86eed4f0661725921c6e22e6883762d

And that’s the minimum you can do so you have the right amount of Triangles.

I guess my question for this post is, how can you make your mesh smooth without actually going over 10k tris?

Thank you

It looks like you’re going to need to optimize the mesh somehow without ruining the “smoothness”. If I remember correctly, there is another way. You can change the faces to “smooth”.

Go to Edit Mode
Hit CTRL + F.
Find Smooth.

Otherwise, I must have missed something, I haven’t used Blender for a while.

Hello, I attempted this and I can’t seem to find smooth.

Although, I found this and pressed Smooth but nothing really happened.

How about using smooth shading?
It can be found in the toolbar (T) after selecting the mesh

Smooth vertex?

30 Characters aaaaaa

Wait, smooth shading was what I mentioned above.

It did nothing unfortunately.

Did you select the mesh and then apply Smooth Shading? (Make sure you’re in object mode too)

Yeah, I’m actually very confused why this is happening, but it’s not doing anything. Little proof: https://gyazo.com/b00bc78cfb8e29bd5362c4a7039e7b4a

I’m not exactly sure what is causing this either. What if you close Blender and do this again? Does it solve the problem or is it the exact same?

It’s probably because you have overlapping vertices or flipped normals. Try going to edit mode and remove doubles, then recalculate normals. Go back to object mode and do smooth shading again.

If you’re using Blender 2.8, it’s as simple as being in Object Mode, clicking Object, and clicking Shade Smooth.

Additionally, you can get this to look visually smooth with as few as 108 tris (54 faces). Yay low poly models!:

Unfortunately not, I am a 2.7 user.

In Blender 2.79 or earlier version, while in Edit Mode, use Ctrl + F to open the Faces settings, and click Shade Smooth.

Also, if you’re new to Blender, use 2.8, it much more intuitive to people who are new with the software.
