How to apply displacement in shaders

[eunchae]

Hi.

I want to apply displacement to the area I want.

For example, I want'dis' to be applied only to the red area as in the image.

But I am not sure how to do it in the shader.

Could you please let me know?

Or maybe it's a reference address.

The example file is also good.

Thanks in advance.

You just bind in your Cd attribute and then use that to drive the displacement amount.  I included a minimal example, but the principle is the same when using premade shaders like Classic/Principled.  If you do it yourself don't forget to turn on the vm_displacebound setting on the object.

Thank you very much!

I have a question again. Where should "smooth" connect to the displaced part? (From Shader)

The edge is too sharp.

Thank you.

look at the 1st pic, between red/blue....there simply ain't enough geo for a smooth deformation.

try your sphere frequency say 50 ?

I don't know anything about displacements in renders tho, so could be wrong.

Thank you.
