Animating along a path/texture animating---Conveyor Belt
show user profile  msacchit
Hey, I'm new to max and am trying to figure out how to create a conveyor belt. I want the belt spinning but I also want a fastener on top of the belt that moves at the same speed, so what I came up with is this...I created the belt using a spline, then applied a texture to it. I used the outer edge of the belt (after using shell to add thickness to my extruded belt) to create a shape for my fastener to follow. I used motion to make my fastener follow the path, and then attempted to use Wire Parameters to link the U Offset of the texture on the conveyor belt to the position percent of the fastener. What I am getting is close to what I want, but not quite. The fastener and texture are slightly off in the speed they are moving, so the fastener slowly slides off line up with the texture. Any ideas on what I can do to correct this? Thanks

Can't you just use the 'attach' tool (vert mode under edit poly) to stick the fastener to the belt?
I would also look at path deform WSM for the whole thing.

It is likely that the mapping on the belt is not really normalized.

To do that, make a copy of the spline to use as a path later, apply an Extrude and then convert to Ediable Poly.
Add an Unwrap UVW, go to face sub-object level in the Edit UVWs dialog, select everything, go to Mapping > Unfold Mapping with Normalize Clusters checked.
Now the width of the mapping is perfectly stretched to the width of the UV space. You can snap the top row of vertices to the top of the UV box if needed.
Converting to Editable Poly is important because it gives a quad mesh in the Unwrap UVW. Otherwise you get a tri mesh and when you unfold the mapping, you'll probably get triangles at each end. And scaling the width manually will give an approximate result.

Wow, beautiful! Best tutorial I've seen all day, Garp. Didn't even think of doing a conveyor belt is such a simple way.

Now you've done it! I feel all warm and soft inside.
I don't understand the reference to Minimal Viable Product, though. <:|
