Low Poly Lighting Question

Anonymous — Mon, 21 Dec 2015 19:57:08 GMT

I am very new to 3D modeling and I am new to low poly modeling as an artistic style. I created a crater using Maya 2016 that is fairly low poly. (image 1)

The lighting of the object is not how I want it to be. When I export it and put it into Unity I get the same lighting problem (image 2). I want the faces to be hard lit, how would I do this? I keep trying to find information about it, but have had no luck. (image 3)

Thank you!

What shader are you using...looks like a cartoon style shader maybe mental ray?....remember that some shaders from Maya are not meant to be used in Unity.

I am using a lambert shader.

I got ahold of a model that has the lighting how I want it to look. It is a lambert as well (images below)

When I put it into my Unity scene it had extra objects attached to it such as the black and white image (circled in red). What is this? Maybe that is what I am missing?

You can just delete the piece you don't want... Now I'm not sure what is the problem with your lighting question.

The images above, I am trying to get my crater (object on the left) to light like the object on the right. I cannot get them to look similar though. Even though I have copied over the material there is still a problem with the crater not having geometeric lighting/shadows, and im not sure why.

Does that help a bit more?

That has more something to do with Unity , you have to try to use Unity lighting features and maybe use Unity's shaders...

I did notice however that the Normals are different in those two shapes, maybe that's what you are after, one object has Normals-hard eges (right object) and the other on the left has Normals -soft edges.

You can fix that in Maya and import back into Unity.

damaggio, thank you for all of your help.

I made it to where the display edges are hard in Maya and that did not help. Any extra guidence in Maya would be helpful.

Okay Ray but I'm still confused here, did you get rid of the object you didn't want?

In this latest image the objects are quite different from one another..the one on the left is your crater right?

I am sorry for the confusion. Let me try and explain it as best as I can.

The image on the left is my crater. I need the lighting to be similar to the one on the right. I am trying to achieve the hard lighting. ( I did not make the image on the right, I am using it as reference/ example ).

I do not know what I am missing to get the lighting on the 3D crater to have hard lighting. I feel like this is a simple task, but I have been unsuccessful in doing so.

Here is another reference image. The crater on the left is what I made, the object on the right is a reference image that I did not make and I am trying to recreate.

Thank you!

Okay, I think iI got it before, the image on the right has Hard Edges....select your crater on the left and go to Mesh Display>Unlock normals...then again do a Harden Edge.....that should do it.
