SubD examples and models

very funny

Great modeling, use of Subdiv and cartoon render...but just as important, full of character. Love it.

Thanks All I very much appreciate that you like this little simple "character" fun

I post my models here because I want illustrate to others who may be interested in Organic modelling that it's quite possible with Sketchup, largely because of the amazing extensions (QuadFace Tools, Vertex Tools 2, and SUbD) that ThomThom developed. The more I work with them the greater appreciation I have. Model on!

The painted low poly model was later edited to improve on the leg detail. You can see in the Substance Painter example below how the legs had lost their definition after subdivision. I later used QuadFace Tools to add loops to maintain shape.

I used the free trial of V Ray and Substance Painter to add some realism. I have not had any prior experience with either so the results are not good, but they do help to add some realism.

Klasse! Great work again. (I love these SketchUp illustrations even more than the rendered versions)

A short biology lesson . Nice

Thank you HornOxx. I tend to agree with you. The thing I like about Substance Painter is being able to stay in 3D. But I know what you mean about the raw modelling illustrations. Cheers

Too funny The reference photo helped me to redraw the legs to keep their shape and definition

A compliment of the highest order hahaha. Thanks tuna1957

My favorite Sci-Fi character

Builder54, Great job on a complex character !

Now to return to earth..... as time allows I go back into my early SubD models and try to fix "rookie" mistakes. Reworked one of my first SubD sofas. Lots of mistakes in the first go round . Second time around looks much better and even lower poly to boot....

Thanks very much!

Interesting you mention the lower poly count. I'm becoming increasingly aware that my models have way to many poly's, and the key is to keep it simple and strategic.

Hello! I noticed that when I use SubD, it creates some polygons that are not really necessary, making the file bigger. You can see in the example below:

Polygons generated by SubD

Here I erased some lines just to show that they were not necessary.

I tried using TT's cleanup, looks like it removes some "random" lines. Of course its not random, but it leaves a lot of lines that I can erase and keep the same geometry.

Any tips on how to optimize it?

See if 'Fixit 101' will get you where you're going.

It's propably because of the SketchUp (inofficial) quad definition:
"two triangles share an edge which is soft and smooth - with Cast Shadows turned off"

I think this is the way Open SubDiv works, it subdivides polygons and does not care if they are coplanar after subdivision.
If you use the Cleanup plugin after you are done with subdivision then you are actually doing decimation of that model by removing edges from coplanar polygons.
Where you can get in trouble after you do Cleanup is texturing where there could be some distorted texture on those polygons.

You could try tweaking with Vertex Tools Merging Close Vertices. It's demonstrated in this video

Thanks! Great plugin by the way. It worked better than cleanup, but still left some coplanar edges, and looks random too, that will give me trouble when texturing. (See attachment)
