Hi
You test shaders in OpenGL.

Thinking about adding OpenGL renderer in Esenthel?

I want to test if its reasonable to make Mac/iPhone/iPad port.
Windows PC will use only DX9 and DX10+ rendering.

that would be a great addition! and don't forget linux :O

If you create a port on the iPhone / iPad, on which licenses will be available? People who are already licensed will be able to use the port?

it will take some time for a port to be ready, and its not yet confirmed that there will be ports.
so I can't say anything about license information yet.
