3D Postwork: Compositing Multiple Renders

leave a comment »

Getting the perfect image is hard to do sometimes with renders out of the box. Not to mention renders take a really long time (on my computer at least). Luckily image editing software allows us to change lighting, color and texture from outside the 3D program.

From this:AikoUE To this:AikoFinal

Getting Rid of Feet Poke-Through (DAZ Studio)

leave a comment »

I have a decently-sized collection of 3D content for DAZ Studio but I never actually use it. Or I just do little renders on white backgrounds which have no artistic merit to them whatsoever. Anyway, I was trying out the UberSurface shader that comes with Studio 3 Advanced today. Loaded The Girl 4, some clothes, posed, but alas! Foot poke-through!

I used to think that you’d need a Hide Feet pose (like the kind that came with Gen 3 figures) to solve this but it’s actually much simpler.

Select the parts you want to hide (in this case lFoot, lToe, rFoot, rToe) and toggle Visible to Off under the Parameters tab.

Alternatively, click on the eye under the Scene tab.2010-01-27_155226Et voila.

Drawing from TV

leave a comment »

I read Glenn Fabry‘s book Muscles in Motion: Figure Drawing for the Comic Book Artist recently. The book is not really that great, but it introduces a fairly easy way of getting practice drawing subjects in poses that would normally be difficult to do from life. Fabry drew figures from videotapes (fitness tapes, bodybuilders…) to amass a vast personal library of poses and anatomy reference for his comic book work.

His basic methodology:

  1. Get a tape
  2. Stop at a suitable point (in exercise tapes this was virtually every exercise, really)
  3. Draw
  4. Forward a few frames
  5. Repeat steps 3-4 until the tape spoils, buy new tape, go back to step 1

I haven’t got any fitness tapes handy, but I did have a few episodes of Mythbusters on my recorder.

I tried this with a Peking opera that was showing as well.

Obviously this isn’t going to increase my people-drawing skills (not the faces, anyway…) but I like to think of it as quick training exercises. But there are also times when I’m watching something (like The Life of Mammals the other day) and I think to myself “damn, I gotta draw that!”. But my sketchbook is in my room, and I really just want to watch the monkey catching and eating the flamingo. To counter this I am planning to leave the sketchbook on my coffee table, together with a 3B pencil.

Why 3B? For me at least 3B provides that nice balance in between rich tones and fine control. Then again, with these drawings, I suppose it’s more about capturing the gesture than absolute control that matters.

Painting Knife

My new painting knife: Brandless No. 6

While waiting for my turn to buy uniforms today at Beauty World I couldn’t stop myself from wandering into Art Lab and looking at the paint section. The staffer today was really friendly and helpful, a stark contrast to the staff who were there the last time I visited (a surly fat lady and an equally surly skinny woman).

I couldn’t help myself and bought a painting knife. A bit of backstory.

I bought a Winsor & Newton System3 starter set the other day, determined to make myself competent at acrylics (I have hated them since I first tried painting with them when I was thirteen). So far it has not worked. I mix paint with my brush, which means that the paint gets spread out pretty thin. With oils, this is still all right: I drybrush a lot when adding detail. However with acrylics, due to the larger surface area, the paint dries so fast that I can’t even finish painting a background before I have to mix a new batch. And naturally this scenario repeats itself with the second batch although I am working as fast as I can.

A palette knife or painting knife – palette knives don’t have the big bend in the middle, but both can be used for mixing – makes managing paint on the palette a lot easier. You can fold the paint in on itself to get a well-mixed color. You can scrape thin layers of paint together into a more substantial pile before you use it. They can also be used for mark-making as part of the painting, but for the meantime I just hope it doesn’t become another art white elephant.
