Canyon Terrain - some errors on texture

cosmo71

At first, the canyon terrain is really great and I have done a very good render with it but I want to do another and loaded the canyon terrain high res + an ambient light and one distant light with ray traced shadow (shadow bias at 1.0 standard, shadow softness 10) at that was the result. Can you see the mesh? I can. click for larger view.

What product?

Pretty sure it's a Shadow Bias issue. Try lowering your bias to 0.10 and see if it goes away.

Also, did you load Canyon terrain Low, Mid or High?

Scratch that - it's Shading Rate. Just did a test with shading rate at 2.0 and I can see the issue. If I go to 0.20 I cannot.

worse, I came from 0.01 and ended up at 1.0 higher than 1.0 is bad for shadows (clothes on body for example)

just the terrain high res and not the preset close up.

not bias but shading rate? where do I have to change that?

cosmo71

ah, yes, it is the shading rate, have changed it to 0.1 and the bias to 0.5 and all is fine

happy new year

here is the latest render I have done with the canyon terrain (it is the close up preset with other than the original lights) and in this render the canyon terrain is great, have lowered the shading rate to 0.5
