Maya 2020 fundamentals - modelling the real world
Get halfway through a model and find it's an unworkable mess? Can't add edge loops where you need them? Can't subdivide a mesh properly? If any of this sounds familiar check this course out.

Polygon/FillHole leaves artifacts on object
Thank you to daverave and perfecto for answering so quickly to my previous question.
It's a beautiful Sunday morning somewhere north of Toronto, and yet I suffer in newbness.
Please see the screencap below.
I created a pod racer from a polygon square with lots of extruding, scaling and moving. Then I smoothed it.
At some point after that I realised there were a few holes in the shape.
I tried to patch the holes by i) selecting the shape and hitting polygon/merge/fill hole ii) selecting the edges of each hole and hitting polygon/merge/fill hole and then using merge just for good measure.
The holes got filled in both cases but with visual artifacts.
The filled holes don't seem to take the assigned shaders or textures very well.
I have 2 questions:
1) How can I fill holes in polygons without getting these artifacts?
2) Are there any tips for selecting components on objects without inadvertently selecting other parts of the object?
Cheers
Tom

Don't be satisfied with what you can do but rather strive to do the things you can't do!

Thank you for the replies.
Dave - tried the polygon/mesh/cleanup but was unable to change anything.
Perfecto - I have tried filling all holes at once, 1 hole at a time :all edges selected, 1 hole at a time: 1 edge selected - but none of these differences seem to make a difference.
Stewert - I checked the face normals, the faces and the geometry in general but everything seems normal. No pun intended. By the way, love your Lego models. Very cool.
I did find a residual, larger polygon face that was on the inside of the model hidden by the mesh on the outside. This larger piece corresponded to the original hole but was not tessellated to the same degree as the surrounding mesh. Once removed however, nothing changed.
I'm not sure if this is a modeling issue or a shading issue.
Grateful for any other ideas or suggestions.
Cheers
Tom

Thank you for the suggestions.
I tried normals/set to face but was unable to change the appearance of the filled polygons. The only way I could get a consistent look to the whole podbody was to select the entire body and then do normals/set face which resulted in a zeppelin like canvass stretched over frame appearance and not the seamless smoothed appearance of before.
I'm not sure how to export as an object. It's not a choice I'm given in the pull down menu in file/export selection/file type menu. I tried exporting a mayabinary file and reimporting it but not a lot happened.
I am a complete newb so don't assume too much. I could be failing to do something very basic.
The only way I can get the smooth appearance is to smooth the object again which is not great because of the extra polygons and their irregular shape.
Any further ideas or suggestions greately appreciated.
Jay, Your Gordon Ramsay is a classic by the way. You nailed him. You were quite kind to him, but you captured him brilliantly.
Cheers
Tom

You can also resoften the normals you want by selecting the relevant edges, and go Normals > Soften edge...
Hope that helps.

1. Like stwert said...Normal>soften edge
2. After you click soften edge, you should see the polySoftEdge node in the channel box. Click on it to expand it and you will be able to change the value to whatever look you need.
good luck

i've not used that command before but i assume you can do that again and do what stwert said about soften edgesOriginally posted by Tom Knowles

that's a "Ch" pronounced as a "K"

Thank you very much for all the suggestions.
normal/soften edges worked a dream. the podbody has regained its baby smooth appearance.
There were a few polys over polys (see my previous comment), and they may have contributed to the split face appearance of a couple of the polys.
I do have a further problem related to this problem but slightly different, so I'm going to start a different thread.
Thank you for all your help.
This place is awesome.
Cheers
Tom
