Xlights Custom Model Sequencing

[Uncle_Tom]

Trying to get a 'simple' letter "J" (will be JOY) to light up sequentially. Physical model is 7' x 4' x 8" for each letter, sequencing is 'supposed' to go around perimeter of letter 1-93, then inside loop 94-178 (virtual string) is a 2nd loop on continuous string to "sparkle". The 'custom model' is sweeping across from left-to-right by column in-lieu of the perimeter motion. The pic shows the #-ing on how it should go. HELP!

Could you perhaps export that model, what little I can see numbering looks OK, but need to see how you have set up the sub-models?
Bit confused as to what your issue is, are you trying to get lights 1 to 93 to light up one by one sequentially whilst at the same time the inside 'row' lights 94-179 is just sparkling? If so could you also post a screen snip of the effects in the sequence.
