Indybot

This week’s drawergeeks was Indiana Jones. Since I’ve been sketching so many robots lately, I figured, why not? Keep reading for a bunch of step by step stuff.

First came the sketch. Sharpie on post it notes, of course. (shhhhh, this was drawn during a meeting.)

My really simple robot drawings translate into really simple 3d models, which is fortunate for me, as I’m not much of a modeler.  Here’s the wireframe of the bot.

And here’s the wireframe shaded and angled so you can see some more of the form.

So, here’s what he looks like with simple shading.  Not too bad.

But I decided to see what he’d look like if he’d been through the ringer a little more. Beat up. I mean, he’s still an Indiana Jones architype right?

That’s a little more fun. Okay, now for some textures. The textures on this are really very simple. Here’s the shader network for his head textures. As you can see it’s just a color map and bump map. I wanted the dirty/rusty areas to not have any reflections, so I also used a reflectivity map to control that.

And here’s a test render with the textures. They’re looking okay, but hoo boy, that lighting blows.

I created a high dynamic range light probe image of our downstairs bathroom from 5 different exposures. I used this as the basis for the lighting for the scene. (notice the high tech christmas tree ball I’m using for the light probe)

I also created a fog version of the scene so I could use it as an alpha channel in photoshop to control the depth of field, as well as the saturation back into space.

And here’s the final render again, with the nice lighting, depth of field, etc. Click it for a bigger version.

And here’s a bonus zoom in of his head, just for reading through this whole thing.

oh wow, bryan!!!! that is soo coooool! the textures are awesome.

jeremy did a robotish one too. big surprise. 🙂

i didn’t get a chance to do one this week…. 🙁

Uau! Great Indiana! a real step by step… You must be an awesome teacher Bryan! Thanks for this on line 3d lesson! b.

this rocks the house. The cave was that finishing touch. wonderful work… again. This is getting to be quite routine.

Hey Mike, thanks. Awwww man. Well, I’ve been unable to do ones recently too.

Thanks Bruna! I actually like putting together step by step stuff. I wish I had more time to do them.

Hey Doug, yeah, the cave seemed to pull it together. You can thank Mr. Vanhoozer for the suggestion.

This rocks! I love the close up, it almost looks real.

One question. Do you alwasy have to use the light ball thingy? Is it just to make it easier or is it an actual part of the process? Just curious.

I just love this. How awesome. I wish this guy really existed somewhere as a toy that I could buy. His whip is hilarious too. Nice job Bryan!

Thanks Cristina. The light ball is just one way of lighting scenes in 3d. But it can give you some really nice lighting because it’s based on specific real world lighting.

Sarah, you don’t know how much I want to design toys. There are some awesome vinyl toy companies doing really cool stuff. I tried contacting a few, but no dice. Oh well.

Ohhhh… thanks. I really like your shiny chritmas tree ornament by the way.lol

Another fine 3D job. The rusty texture is very lifelike. The light up whip is totally Ballinger.
