ubernoise drift

[Dantetron]

Hello, crew.

I have a situation where I created a material using OSL ubernoise.  And it's not behaving itself.

The texture is not pinning to the object and drifting. This anomaly only occurs when rendering using the GPU. And even then it is inconsistent.  In response to this issue I've spent half a day experimenting with ubernoise and GPU and have produced results without the drift but it's inconsistant.

I've attached the project file. I'd be curious if anyone else get the same results or see's a glaring reason for the drift.

Thanks!

There are so many more ways to animate that mesh where that would be expected, normal behavior, than to animate it in a way where that would be "anomaly" as you say.

There is also many more mapping systems where any kind of animation would result to some kind of "drifting" 

3d maps dont use "standard" 2d UV mapping as default system...

If in doubt you can check with default (Nitrous) D3D viewport rendering and realistic material, it will show you right result

All-

I found an obvious remedy to my problem.  By simply attaching a UVW Transform material modifier to Ubernoise, it pinned my texture.

Why didn't I do this to begin with? Because I've never had to. Ubernoise is my default goto noise generator and I use it quite a bit. (BTW- adding a UVW object modifier didn't work).

So, Domo may be on to something. Don't simply trust the default UVW mechanism that determines how textures behave on an object?

Thanks!
