Anyway I am not using render targets to achieve my targets. But I have only one problem for now. It seems that the alpha values of my render targets are always 1.0. How can I output the alpha values though? Do I need to write my own shaders? Quote Link to comment Share on other sites More sharing options...

Now I have worked out what I expected. Actually the only problemI have is that every time I add a new mesh to my selection group/layer, I need to update the Octree otherwise I won't see it. Anyway I will keep my current solution. Basically 1. first I clone my original selected mesh and apply a base layer selection material. 2. then I add an overlay layer (alpha = 0.2) and render it to a separate render target. 3. Then in the final compose shader, I apply a simple edge detection algorithm. Arte 1 Quote Link to comment Share on other sites More sharing options...

Hi Arte, I am sorry because I am not allowed to share my code for now. Hum...but actually it is just a Sorbel edge detector. You have bunch of information on the Internet.
