in general this should not be viewed as a rendering library, although it feels like one (which is ofc intended). its more a convenience node set to draw stuff with VL in a structured way as you are used to from vvvv. but you should always think of vvvv as the rendering engine.
outlines are not trivial in DX11... feature for later.
this is not possible, instancing is a technique to get the best performance out of the graphics card by pushing one draw call that should be executed thousands of times. a draw call can only have one geometry and one texture. so its not directly like spreading in vvvv. if you want to spread the texture with a quad, just put it in a loop:
yes, blending is a good idea, this can be spreaded in DX11... should be straight forward. alpha can already be set via the color. but alpha never works well together with the depthbuffer, be aware of that.
sure, should be an input of the renderer... as other lighting properties.
that's not the scope of the library, maybe in the future...
general advice, you can always make a copy of the Renderer (CraftLie) in vvvv and customize it as you need it. it is also not a shame to output more than one description layer out of VL to feed it into multiple Renderer (CraftLie) nodes with different settings for each... CraftLie is there to make your life much more easy, not restrict it.
thanks for testing and your thoughts on it!
