Height map

[Anonymous]

hello, I am having trouble with the height map. When I apply the height map to my model it goes all over the place. I am not sure what I have done wrong??

Hi @Anonymous and welcome to the community!

It could be due to some of your settings in the displacement node itself. Solid Angle has a breakdown on height nodes you can read here!

Also, when you get a chance can you please zip and attach the project folder with the height map here or via dropbox/google drive or another file sharing program so I can take a look at it?

Let me know if anything changes!

Thank you for your help. here's the link to the project file. https://drive.google.com/file/d/1f-Ee3Z5BNnDFaMYx3phR4f4gRN0aWcAl/view?usp=sharing

okay I got it to work by adding subdivition but the displacement is really strong on one of the side??

Hi @Anonymous

Thanks for attaching the scene file!

I've been doing a lot of testing and this is a pretty unusual issue. There's actually nothing wrong with the height map or the shader, the problem is somewhere in your geometry.

I applied this shader to a plane, sphere and cube and had no issues but when I started deleting certain sections of your building it started to look normal again.

Basically Arnold is having trouble showing the height map with the holes in the wall.

How did you go about making this? Did you use booleans at all for the holes in the walls?

Thankyou for taking a look at the file. I made this by extruding the plane. If I were to do it again how should I go about approching this? Or is there anyway to save it?

Hi @Anonymous

If you made it buy using a plane then it's unusual that this issue is occurring.

I would make a cube that has the right thickness, then add edge loops so you can delete the faces where you want the windows. 

When you get a chance, can you try this and see if this issue still occurs?

Hi @Anonymous

Just wanted to check in to see how things were going. Are you still having this issue?

Sorry for the late reply. I haven't got it fixed yet. I will try the deleting of the face when I have the time. As it looks fine with the texture and the rest of the built. Thank you so much for your help.

Avoid having scale on your Transform nodes. If you don't really need it, all Scale values of a Transform node should be [1 1 1].
Select all Components (like Vertices or Faces) and scale them for modeling or use Freeze Transformations ("Scale") after you scaled the object with a global scale.
