For the discussion Is Within Box Get Color, I think the solution that you suggested, Bodysoulspirit, would actually be more efficient. Rather than building a list of 3D objects and then extracting their colors to send as DMX, @Xavier dev can build a list of colors and use that list both for creating the 3D objects and for sending as DMX.>
Yes, actually, I followed your recommendations and work on this color list as the attached file. It's better that way.
On the issue of "node hold", I work on the idea of injecting 2 "process list" into an "Is within Box". Following the recommendations I placed the hold nodes to avoid the flicker. After several attempts, the problem does not seem to be solved in this configuration. Maybe I omitted a parameter or that the problem comes from elsewhere. Could you guard me on this subject, thank you.
