Over-sized wheels

Post by **Phineus** » Thu Sep 25, 2008 12:14 pm

When making trucks of an unconventional size you sometimes run into wheel problems. For very large trucks, the wheels sink into the ground. For example, like this

The same problem occurs for Bigfoot 5 replicas.

The problem is that in mtm the wheels ride at a constant height, so that any change in wheel diameter will result in the tire sinking below the surface, or riding above it.

For very small trucks, we can compensate for the tires riding too high by making tracks especially designed to accomodate them. This is where the -ST- or "small tires" tracks come from. They allow undersized wheels to look normal. This is achieved by making the texture depth deeper than on a normal track. The whole process handles slightly different than stock mtm tracks and trucks but it's quite manageable.

Unfortunately, nobody has figured out a way to make over-sized wheels look right.

Thanks for the advice Phin, it's Monster Mora's last project. Not released yet.

Sometimes it can't be helped. What I learned on mine is to make the wheels smaller, compared to the tires. That way it gives the "illusion" that they are bigger than they are, but not as realistic, but it doesn't sink it, or float.

Just gotta play with it. I made mine to be a race truck anyway, on a dare, and it's to this day one of my best handling, race trucks I ever made. Not many know that, cuz they think it's silly, but I've whooped some booty on the Zone with it...

I still wish soemone would make Max Damage's car, I can't even find a good picture of it online...

And remember C-POD <a href="http://ch.mtm2.com/c-pod/type.php">can automagically convert</a> any track to ST format (deep texture depths) no need to unpod.
<table width='100%'><tr><td>

Code: Select all

The track type list box is located in the bottom center of the
  program window.

  Double click the current type for the menu of choices.

  - Small Tires Format [ST]
               This configures a track to be used with vehicles
               conforming to small tire *st* format.  Tracks converted
               to ST can be converted back again.

Strangely, this problem does not occur in Monster Truck Madness.

Here is a pictures of TruckORama's Bigfoot #5 in the garage.

The wheels a as they should be.

Here it is in the Monster Truck Madness 2 garage.

Back to the "sinking wheels" problem.

roadknight, I notcied that the tires on BF 5 on MTM1 were closer to the shocks than in MTM2

You're right, I've now just noticed that. I prefer that to the wheels sinking though, myself.

Awesome find, Roadknight! I think we a have a new researcher

Really?! Who's that?

Lol, I'd be happy to be part of the "Monster Truck Madness research team".
