Im following this tutorial: https://www.sidefx.com/index.php?option=com_content&task=view&id=2500& [sidefx.com] , but on 05:15 hes promoting the colormap, but I cant find this option anywhere. Has this been updated in version 15?

I find promoting kind of tricky on those nodes as well. The promotion area is actually a very small rectangle over the socket connector. So try making sure your mouse is in the right place. But there is a second way to promote which is to simply select the node and then move your mouse into the parameters window and scroll down until you find the field listed. At the very right-hand side of the field there is an icon that you can click to promote that field as well.

I tried what you said and looked everywhere, but I cant find anything about promotion nodes in 15. Looking forward to updated tuorials

Hi,
I have attached an image to what it looks in the new Houdini 15. Hope this helps
