Hey, pretty good! You got the 8-bit thing going.

I've started an AMReport: [bug]6246[/bug] Baked Bump Maps do not shade properly

If you ever have time to summarize/organize this into an article or tutorial that would be a fine thing to do.

I recommend you make up a simple test case that clearly shows the problem and submit that to AMreports. Bump mapping seems to work great , but not with baked maps.

The problem with those gifs is it all flickers by so fast we can't really study it.

I'm sure Rodney meant "frames per second"

-possibly you have "step" set to something other than 1 -possibly you don't have the Range set to what you thought you did?

A spline is an infinitely thin area but the reversal of the lighting happens over real area so it's got to be something happening on the patch.

Now I've added the complication of baking the decal. Would you say this shows the same problem you have? The left models have the map applied as a regular decal, the right models have it baked. the top models have it set to Color and the bottom models have it set to Bump. BakedBumpTest.zip

In this simple example the problem shows up in Progressive render but not Final render

I'm looking at your sample case. The problem seems to be on 5-point patches but not on all of the 5-point patch. It looks like part of the patch works right and part does not? I wonder if it's possible that one of the sub-patches that A:M creates to fill in 5-point patches has its normal reversed? Each side of the patch is divided into two. They meet in the middle. This creates 5 pieces in the patch. And the pieces do not always have the same direction of normal. It is a problem with the subdivision of the 5 point patch I think that could be fixed, we just need to make a really clear example case for Steffen to look at.

I have wanted to do that! I need to get a second camera so i can capture things like that at two angles.

He's a charmer! I like that.

That's getting better. I think you could slow that down a bit for clarity. it's 15 frames now... maybe 18 or 20?

I can see the advantage of getting tricky shape things like those hair lines interpolated, and of course being able to do most of the character animation in 3D and make it look 2D at the end could be a huge gain.

You got me thinking about this so I made some reference footage. It's shot at 60 fps so you can step through it to see details. http://www.hash.com/forums/index.php?showtopic=43761

A moderate jog and fast run with various enhancements for study: JogRunComparisonH800.mov Interesting detail i noticed... the arm is more extended when it is pushing back and drawn closer when it is being brought forward.

Why is baking with tiles better than a continuous decal?

To me it sounded like something for simulation data, like for fluids or gases?

Good looking bump map! What happens if you change the map to "displacement"?

What happens when you run v17 right now? And does v16 still run?

I have a suggestion... put more hips into it. When the right leg goes forward the hips turn to put the right side forward too and likewise with the left leg/hip

That's pretty cool. I presume the propulsion is still from the rubber tires, right? I remember seeing some thing like that in the old Lucius Beebe "Highball" book. I recall an old movie where two guys get their car to ride the rails by letting air out of the tires. Of course, that didn't end well.

If your v16 license is current you can also download and run the v17 version. After you install the v17 version, copy the "master0.lic" file from your v16 directory to the v17 directory. you can use both (and any other version that comes out) until your license expires.
