loft Nurb caps invisible
I’m a newbie to 3D and have just started using Cinema4D 11.5. When I create a loft Nurb with spline objects the start and end caps are invisible but are selected in the caps tab. My splines are connected linear a b-splines. Any suggestions would be much appreciated as I have been trying to sort the issue out for some time with no success. Ran

if you selected Loop in the Loft settings you would not have caps at all

The Loft setting is not selected. All my nurbs have caps except when I use a spline that uses different spline types connected. It just will not put a cap on.

how did you connect the two splines?
-
or did you mean connected because they are both in the Loft Nurb? It should not matter what type the splines are in that case, you should still get caps.
The only other thing I can think of, at the moment, that will kill the caps is if the splines are not Closed.
If it’s not either one of those I’d have to see the scene file.

Thanks Brian. The splines have been snapped together then grouped and connected. Still no caps. How can I send you the file as this is frustrating as I am spending so much time just trying to create one shape I am after.

attach the file using the File Upload button in the compose page
follow that through to upload your file it will give you a link – copy and paste that back into your post

each of the splines is made of 3 splines you have connected but not actually joined together (the ‘sharp’ corners all have two points) so the spline can’t be closed (well, you can close it but each separate part of the spline closes on itself).
If you select the 2 points at a corner and do a “Join Segment” (in the Mesh/Spline menu) you get a rounded curve since that point now becomes the spline default of B-Spline. Do that for one of the other sharp corners and part of the spline disappears (but you get it back if you Close the spline).
To get the ‘sharp’ corners back while keeping the B-Spline shape of the curved section you have to Chamfer the sharp corners (just a bit so the result will still be pretty sharp) – which turns the spline into a Bezier spline but you just have to turn it back into a B-Spline and you are done.
Thanks Brian.
I’ll give it a go. I can not give open splinefix file is an unknown format. I’m running CD411.5.
ahh, I’m running 14. If you can’t get it to go I’ll do it again in 10 or 12 (whichever you can load) – I never owned 11/11.5 – but it’s pretty easy.
