raindrops displacement

Recommended Posts

Im trying to make ripples in a plane using ripple displacement effect.   I was following a tut and did everything he says but cant see any ripples when I render. Anybody clue me in why please? File attached.   Here is the tut -

I see you used the ripple shader.

The ripple shader is only visible in the picture viewer and not in the viewport.

My guess is that's problem.

    I am using the picture viewer. I had to check sub polygon displacement.  Not sure what that is but works once its checked.

    When you deform stuff in C4D, there has to be enough geometry to give the required detail. In the video, he mentions subdividing the plane mesh to this end. SPD achieves the same result by calculation instead of permanent subdivision. Rendering real subdivided mesh is quicker than the SPD calculation method, but a subdivided scene can slow down the viewport and increase filesize.

     

    You can get the same ripples by either method.

    I did do what he said and increased the geometry the same as the video but until I checked 'sub poly displacement'  it didn't work

    Here's a quick test using 2X subdivide and SPD off

    just noticed you in Oz - it's 3.45 am here in the UK ...

    Hi Jed,  So you saying I shouldn't use sub poly displace?  sorry bit unclear.    Its 2:45 pm an stinking hot. Been at beach all day to try get some relief. :)

    SPD seems the way to go - I was just pointing out that it more or less does the same as dividing the mesh.
