Hi all

I went to use the lmt_shade function and it fails with two error 
messages. the first one is:

/metafun > log > error: Not a cycle/
followed by lots of trace messages, then:
/metafun > log > That contour should have ended with '.. cycle' or '& 
cycle'. So I'll not change/
/anything just now./
//
The MWE I used is as follows:
\starttext
\startMPpage
definecolor [ name = "MyColor3", r = uniformdeviate(1), g = 
uniformdeviate(1), b = uniformdeviate(1) ] ;
definecolor [ name = "MyColor4", r = uniformdeviate(1), g = 
uniformdeviate(1), b = uniformdeviate(1) ] ;
draw lmt_shade [
path = fullsquare scaled 5cm,
direction = "up",
alternative = "linear",
colors = { "red", "green" },
];
\stopMPpage
\stoptext

  I'm using:

/system          > ConTeXt  ver: 2024.02.14 13:38 LMTX  fmt: 2024.2.15  
int: english/english/

on a mac mini M1.

Any thougths?

Best wishes

Keith McKay
