This is probably just me being thick, so sorry about that from the off. Is the imageplane plugin from 3.5r3 meant to work with z4? I have it installed and I can load an image fine but the problem is I am trying to tweak to mesh to match the reference. I have never really used reference image directly in zbrush, I have always worked by eye, but this model is meant to look light someone. Once I have the ztool loaded and aligned to the imageplane reference I don’t seem to be able to move the geometry to match the reference image, I am not sure exact what the brushes are appending to but it isn’t the head mesh. Is this even the right way to do this, I have used an actual ztool with a texture on before but it isn’t the easiest way to work.
Image Plane is being updated for ZBrush 4. The 3.5 version has some limitations if you are using it with 4. Setting the Preferences>Picker>Sample Size to 25 may help with adjusting your model against a reference image.
