Help please!

[René]

This is bugging me for a while now; I can't properly align color and displacement. What am I doing wrong and what can I do to fix it? The image here is for testing purposes but the same thing happens with rocks. Any help is apreciated.

Does this work for you, I turned of the World switch in the Transform shader.

[René]

This way it aligns perfectly but it gets warped. This is the part I don't understand.

y got me there...no idea but someone will know...hang in there...they may be asleep at this time

Perhaps the terrain is warped before and it takes over that warp. If you say world postion it won't but disaligns. Perhaps a smallscale compute terrain or xyz shader before masking? Do displacement and color in same area of the line.

I have had a similar problem it's annoying to use world position if you have to do work with the shaders.

I'll try that. Thanks!

I have experienced something similar with fake stones in world position; the colours and the stones will not match each other well.

What puzzles me is that the colours and the displacement are controlled by the same image, but are still interpreted  differently.
Could it be a matter of colour continuity? Meaning that the colour remains in the same place but the displacement is moving in a different direction.

[Dune]

It works with a small patch size and world position off. But indeed, the displacement could well move the skin out of the colored area, the colors 'staying at the basis of displacement'.

[René]

That's bad news. The reason I need it so much is that I want vegetation and stones in the crevices of the rocks. Thanks you for your feedback.

[Dune]

I've tested a PBR texture from the web in a default shader, through a transform shader to rotate 90/90/90, and that works alright. Using the AO invertedly fro crevices works too.

[René]

Does that PBR use a normal map? By "AO," you don't mean ambient occlusion, I suppose.

[Dune]

I do. I don't use normal maps.

You can't really see it, but this is a near vertical wall from a softish (smallest size 1m) basic terrain. I used an old Rome wall to displace and gloss, etc, but left the color (albedo) out. Oh yes and added some lichen.

And after having added some fake stones.
