I'm using objectId and it works well in diffuse_albedo, but I'm having some trouble with it in bump.

Top row is noise driven by objectId in diffuse_albedo, and the pattern seems to change.
Bottom row is the same for bump, but doesn't seem to change.

diffuse_albedo

Code: Select all

def eval(vec3 pos) vec3 :
vec3( 
	noise(
		getTexCoords(0) +
		vec2(
			real(objectId())
		) 
	) ,0,0)

bump

Code: Select all

def eval() real :
	noise(
		getTexCoords(0) + 
		vec2(
			real(objectId())
		) 
	)

This is in Indigo 3.6.20.
I'm having the same problem with blend.

Thanks for any help!

objectID() doesn't work with displace params currently (e.g. bump, displacement) sorry.
Maybe I'll change this in the future.
