Hi, im on the road of learning about shaders, specialy displacement in this case. I made a shader that displaces a texture, filtered and mapped with the uv coords. Doing still renders i didnt notice this, but when i did a simple rotation animation to my sphere model i can see that the more displaced parts of the shader moves or fliks like deforming, its a little detail but noticable. Here is a capture of the area focused on the error. Is there a solution to this? I used the properties vop to adjust the displace bound, could be that? Thanks for helping! and sorry for my english =P

You can probably defeat this problem by increasing your Shading Quality from the default of 1 up to, say, 2 or 3.

This will make Mantra dice the geometry up finer and finer to capture more sub-pixel displacement detail. A value of 1 is often okay for mid-frequency patterns in displacement, but when you have a high frequency pattern, you might have to increase that value somewhat.

I'll bet it'll improve the detail in your displacements nicely, regardless of the animation of the shader.

One more thing you can try is to add a Rendering Parameter called “Re-Dice Displacements”. Read about it here: http://www.sidefx.com/docs/houdini10.0/props/mantra10_0 [sidefx.com]

Lots of thanks! I added the Shader Quality to my properties node and change it to 3 and the displacement looks much much better, i didnt know about it! For now on ill get deeper into editing parametres. Ill soon post my shader rendered again.

Thanks again jason
