Spline end wrong color.

[Peter M. Gruhn]

Apply a gradient ramp to a renderable spline and it's like they use the same mapping for both end caps. So only one end cap has the right color.

 

I have a memory of having solved this once but can not get a solution now.

 

I'm sure there's a solution involving just remapping this one end cap by hand. But I have n splines and that just won't be practical.

The only way I think it can be fixed is apply a unwrap modifier and select that face and relocate toward the color that you need. As long as you don't change the amount of polygons in that spline it should work fine even if you move or twist it.

Could you offset the ramp?

[Chris MacDonald]

out of curiosity what happens if you change the material ID? Anything?

[Peter M. Gruhn]

Yeah, offset was my first thought. I tried a number of combinations with offset and tile but it looks like the border between good and bad colors is zero. If I fix the right side I break the left side.

 

Not sure what you're asking me to do, Chris. If I change the "Material ID Channel" on the material to, say, 4 it renders the same. BUt I would have expected that so I wonder if I'm missing something you're driving at.

 

Thanks y'all. We'll beat this yet!

[Chris MacDonald]

Well I was thinking if you put an edit poly modifier on top, and selected the end piece that is the wrong colour and changed the material ID on it. I doubt it will work, given that the texture will be on channel 1, was more thinking out loud.

 

Perhaps select the offending polygon and apply a uvw xform (and try different values, such as flip/mirror an axis) or a uvw map and try the same?

[Peter M. Gruhn]

Solved.

 

Don't use renderable spline, use sweep. Use Generate Material IDs on that and a multi-sub. Copy the gradient right end color to the #2 material.

Did you use the wire tool from Neil Blevins?
