Hello everyone !
I am sorry if this topic has already been covered but I couldn't find any answers in the forum.
So here is the thing, I have been working for a bit in my scene painting masks etc. But when I opened it this morning, it was
impossible to modify or paint on my group paint or paint node. The weird thing is that when I click on apply to all it does work.
I have tried creating new paint layers, testing on a hole new neutral object but nothing works.
So if this has already happened to you I would be very grateful if you could help.
Thank you so much for your time !

Like many of the nodes in Houdini, you may need to select it in the network view, move your mouse into the 3D window and press the ENTER key to activate the particular functions of that node. The Paint node is like this.
