    Hi All-

    The next version of Sim 2 Tweaking, with improved commenting, contoured terrain, and a TANK!

    I've simulated a tracked vehicle by using twenty wheels, ten on each side, in two overlapping layers.  The classes are supplied for modification of the vehicle.

    The problem of flipping them upside down and not getting driving force still exists, that's Monday's job. Also, still have no color / lighting working, but can see them in black against the terrain map background.

    I've noticed a little wierdness as well, but nothing as extreme as that... For me, it's mostly display issues- no colors or textures appear on *any* robots, not even the supplied 3DX entity.  Some rendered elements that shouldn't be there, but generally similar in size to the elements intended - no more than an order of magnitude different.

    It does show how different graphics cards respond differently to the same code in a fairly spectacular way, though =)

    Your suggestion about creating new projects is well taken, that'll be the way forward in future.

    I have something totally weird happening! The four-wheeled robots each have a wheel that extends off to infinity! There are these giant cylinders rolling around the place.

    The tank has a few wheels like this, but it also has something that sticks up in the air and appears to go off into space.

    I had a VERY quick look at the code, but I can't see why this should be happening.

    Just one other (minor) suggestion - maybe you could create a new project rather than overwriting an existing one. Perhaps that has something to do with it?

    P.S. I've added the image to this posting so that everyone can see what is going on. Maybe there will be some other people who can put their finger on the problem.

    Heh you would think that that by now the 5 year old pixel shader standrd we used would be implemented the same across the board Smiley

    I will post in the newsgroups, to try to debug this

    Hi Ross, good work. Please check out Simulation tutorial 5 on how to assign simple color per mesh (or wheel in your case). Use the DiffuseColor field in the ShapeProperties, or specify a texture per mesh, like sim tutorial 5 mentions.

    Right now the default color for your mesh will be black since you have alot of programmatically  created meshes, with no difusse color or file based mesh.
