gsokol : the node you're looking for is the "normal" node you can find it when you right click inside the graph editor tab : "Add node/normal" most of the basic nodes are there as well. By default the normal node will give you a flat color, but you can plug a heightmap for conversion as well.
is there any way to link two nodes into one switch node? Like for example I have two Switch nodes with different input but I want to switch them both at the same time.
Cheers all! I do know that the grunge maps are heavy, I'd actually used clouds previously by the effect isn't as nice as the grunge. Still, there's a project for us - Cheap Grunge. Rogelio, yeah when it comes to the blend node I also wondered why they didn't have screen and overlay built into the blend node. You can see…
To add to random ideas: Would it be possible in the future to map hot keys to specific nodes? Beyond just the space bar select of the basic nodes. Say if you create a noise node that you like to use a lot and you are making many different graphs at once, and you wanted to map that node to a hot key. Would that be possible…
