What was the way of avoiding this in Artlantis?

I thought I remembered it was smoothness but it is not changing anything here. Then I thought it was related to the default shader so I tried basic shader and nothing changed.

Artlantis 2, default or basic shader with a brick texture with a bump.

This is moire.

It is an unfortunate coincidence between the bitmap rendering resolution and your display.

Doe it happen at all resolutions?

Can you make it go away in a larger rendering?

This can also be caused by low quality textures. What is the size/quality of the texure you use?

And turn off bumping - see what happens.

Great, the problem disappears with
- making the rendering much larger leaving the texture as it is (it is a poor texture, 70 pix square for a 3-brick-wide picture), or
- adding resolution to the texture (made image size 5x in Photoshop) without needing to change the rendering size.

I'll Photoshop the textures a bit and all will be fine. Thanks very much.

Or use the Artlantis brick shaders? Or the Dosch brick? Much higher res / quality without visible repeats.

Other than the low res texture in your case, the smoothness slider always does it for me. Used to be (v 1.2?) a mip-mapping option that reduced moire also, but this appears to be automatic in 2.0.

Cheers,

I haven't test Artlantis enough,
but, if my brain still works and not take a vacation I think, other software antialiasing at highest rate should help a bit in lower resolutions? Isn't it (you other people that still have working brains)?
