Hi All,
I have a camera very close to a surface which has some displacement detail
in the very foreground. I'm using the BA raylength shader to try and blend
this so the displacement reduces the further away from the camera the
object is. But it doesn't appear to be working. I've tried to clamp the
scalar range, but even though the BA Raylenth is showing a grad from black
to white on the object, the displacement never reduces.
Any thoughts on how this might be achieved?
Thanks

I didn't play with the RenderTree since a very loonngg time but I think that you could use the "Intersection Point" from the Vector State node.
Then you need to get the world position of your camera and get the distance to those intersection points. I think that they are evaluated before the displacement (assuming you are using MentalRay).

I've been using in the Render tree the node Scalar State in Ray Lenght mode and its working well with the displacement in MR Soft 2012 SP1.
Hope it helps!

Worse case scenario would be to set up two nulls with the right distance in your scene, set their global position with an expression (Distance to cam) in the Scalar Change Range node (Old Range: Start, Old Range: End) and then multiply your displacement with this output value if that makes any sense..

Ideally I don't want to generate a texture projection, just get the
position of the camera and / or other objects in space. Brain's died.
Where can I write an expression in the render tree? I'm clearly
missing something obvious here.

He's just walked in! Diverting him to coffee machine, sofa and Olympics on tv!
Of course the expression is added through the animation divot! I'm an
idiot! Was looking in the wrong place all along. Cheers

OK after all that I'm still getting displacement across the whole
surface, even though I can run the scalar value through a gradient and
it gives the correct result. I've double checked and I'm using the
Vector_State - Intersection Point, so it's obviously not calculating
this before calculating the displacement.
Any other ideas?
Thanks
Chris

ah I see, think in the past for fading off displacements into the distance
I was using textures & gradients in the rendertree - with texture
projection rather than distance to camera. not much help other than that Im
afraid

Yes it is doable i one render pass for sure! I made such RenderTree in the
past.
I'm rather confident that the thing I explained to you (using
point intersections) is working. I will try to put my hands on Softi
today... if nobody else can find the solution :).

Thanks David, but Guillaume has just blown me out of the water, well
and truly! Though I currently can't see what the difference is between
what I've done and what he's done. Just trying to figure it out now.
Thanks

That's really great Guillaume!! Thanks a lot for sending that through.
I genuinely can't see where the difference is with what I've done, but
yours works and mine doesn't. Did you want all thirty of those beers?

he did say 'one' of those and also, havn't loaded the scene (2012 still
here) but doesn't seem any different from the 2nd example pic I sent.
slight problem between the chair and keyboard I say ! :)

I didn't received your email with the pic in my gmail. But checking in my
AD mail, I see it now... weird xsilist problem again?
So yes, you are using the exact same thing :). The only thing to add is a
node to clamp the value that are out of range (to avoid displacement again
after the end of the interpolation).
In the sample scene, I'm using an fcurve node as it looks like it clamps
the values nicely (and add more control in the blending).
