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
