Is there a way to scale any layer in zbrush ?
We can move it using ~ button but can we scale it ? :qu: :qu: :qu: :qu:
It’s not possible to scale a layer. You can use the Document>Resize button to change the size of the whole canvas but scaling up in this way is not always satisfactory.
One thing to note is that providing the canvas proportions remain the same markers are scaled when resizing the canvas. So if you lay out your design at a small scale, marking objects as you go, and then enlarge your canvas using Resize you can re-place your objects using the markers. This avoids the artifacts you get from simply resizing. Aurick used this method in his Lumiere picture:

Unfortunately, though, you can’t use this method retrospectively!
HTH,
Here is a way which might be useful under certain circumstances. Anyhow, it serves to demonstrate the versitility of ZBrush. 
Basically this grabs the info from the layer using the MRGB Grabber tool. I then use my Image Plane plugin to grabbed texture. What the plugin does is simply initialize a plane to the same proportions as the image. I then convert the plane to a polymesh, divide a few times and apply the MRGB depth grab alpha as a displacement. The grabbed texture is applied and then I have a ztool of my layer that I can scale, rotate, move or duplicate as I wish.
Check out the zscript to see how it’s done.
Marcus I dont think this will work for my illustration.
problem is I have created a jungle scene with different elements like trees, sky and grass etc in differnt layers, now I had placed my character in a different layer and made it smaller compared to other scenes, so Just wanted to make the character layer scale a bit. All the layers are baked.
here if I grab the canvas it might cause more probs as it might grab othe layer info too.
I believe better option will be clear that layer and create the character again( the reason why I use different layers) - will be less time consuming
Thanks Btw for that technique - its good to know the technique. I might need it someday in future
