hi there,

i`m having problems using a different mode than WrapAround when using displacement with an image texture...?
it works when using the same texture as bump. how can i prevent the image from tiling?



many thanks for any hint!!

Sorry, I'm not sure to understand the problem. Can you please share a scene as simple as possible with this issue?

Thanks,

Sorry, should`ve postet an example...

in the attatched file//image i use a bitmap to displace a grid.. i also use transform 2d to scale the map down.. but to avoid tiling, i use "Border Mode" -> "black color" on the TextureImage Node..
this works only if i use the map as Bump, but not as Displacement Map...

hope this explains it better ... 8)

many thanks Juanjgon!!!!

The conventional displacement has a lot of limitations, and probably this is one of them. It only works fine over fully UV mapped objects. The new vertex displacement node probably doesn't have this limitation, have you tried it?

Hi Juanjo,

yes you`re right... the vertex displacer does the job!
Should have thought of this in the first place! :roll:


many thanks
