sorry if this is not the right place, but i wonder if i can see the shades smooth just like with Blender

where all i need to click is Shades then select between Smooth or Flat here's a image

i would like to see my polygons like this

It's been a long time since I used Maya, I think you just hit the 3-key or 2-key.

The Maya manual should tell you how.

Do you mean normals?

Do you mean normals?

sorry, but what you mean with Normals?

switch into polygons mode

then

select object

normals > soften edges

in case it doesn't work, select all vertices or faces and do the same

Thanks it worked :D

Normals are what cause your objects to look like that. You can make them face the direction of the face, you can average the normals (not really good for all objects), or you can use normals to create a default lighting look on objects like bushes and trees by using another object to general the normal direction. You should look into some tutorials on them if you dont know what they are or why they exist.
