Oh! Thank you inkBot. Its exactly what I want. We can yet use it as a tool for prototype our ideas but, without being able to use 3D objects with any movement (or physics), it cant help us wih our project. Our chars are all in 3D and our scenario needs some use of dynamic light effects.
We already have Unity and UDK, but probably Unity will do fastest what we need.
Thank you guys, I'll back when Construct gets a plugin of this kind.
