    Hey,

    probably you all know games that show forces/velocity using red colors (bridge building, fighting games, etc.). The more force is applied the more red the object becomes.

    I want to build something similiar. It does not need to be perfect but it should give a good and believeable feedback to the user.

    Some older threads stated that this is impossible to do in Unity but we are almost in year 2015 now and I simply cannot believe that Unity is not capable of doing this somehow...

    So how could you achieve this using Unity?

    It is possible, you just need to think creatively!

    Depends on how realistic you want it (we can quite quickly delve into the wonderful world of Partial Differentiation :p). At the top of my head, a nice way to do this would be something like this:

    1. Stick the object that will go red in a separate layer
    2. Send raycasts downwards from objects and if they hit the layer, inform the stress script
    3. Depending on the stress, interpolate between your texture and a red texture
