Filter nulls


#1

Hello,

Using UV Quads on Surface I am getting a list of XYZ’s that contains some null values, how do I filter out nulls from a list? I have tried List.Filter but am getting Method ‘DoEvaluation()’ is invoked on invalid object.

Type “IsNull” into the search field and use that node as the filtering function for the List.Filter node. If you want to filter a nested list of values you will need to use the filter in conjunction with List.Map node.

Actually, come to think of it, that shouldn’t happen at all. Consider using another quad node. There are are quite a few quad nodes on the package manager, also in packages LunchBox and Clockwork.
