Hi!

Many thanks for this super useful tool. I tried to upload more than two activation maps on the same structural image but I think this option is not supported - right? 

Thanks again!

Great. Many many thanks.

Hello
  
1.) The "Old" flavor only requires OpenGL 2.1 (from 2006), while the regular flavor runs on OpenGL 3.3 Core (from 2008). I suggest you check whether you can upgrade your graphics drivers. One limitation of the Old version is that unless your driver supports specific extensions you will not have control of ambient occlusion or the XRay sliders. Also, depending on your drivers geomtery shader support the wire and wireframe shaders may not work. The nice thing about OpenGL 3.3 is that a lot of nice features are required, so all my software features work

2.) Not in this version, perhaps the next one. You select one transparency value for all your overlays.

-c

Works now, thanks!

Two more questions: For some reason I can only use SurficeOld. When I try Surfice I get "gdk_gl_context_share_new_usefpglex context creation failed" error message. Any idea what am I doing wrong? 
+ Is it possible to control the transparency of different layers independently of each other?

Thanks again!

Hello-

You can load multiple overlays. First choose File/Open to load the background image and then overlay/Add multiple times to load each overlay. Note when you open an overlay a new tool panel appears that allows you to adjust the properties of the overlay.

A nice example of this feature is the painted overlay script you can find here
