Stone material texture movement

[venator11387]

I'm shading some sim geo cached through dopimport and set up with a rest sop and uv project locked to frame 1 so the textures won't move (which I made sure using the uv quickshade and checkerboard material). However, when I use the stone material the stone patterns texture and the bump move around when the geo moves for some reason.

 

I attached a vid below. The bump is turned down for clarity.

Hi Vincent,

 

Would it be possible to upload a file (of just that network is fine, even without your animation) to have a look at?

 

It sounds like everything should work and looking inside the stone shader is appears it's a pretty standard rest setup so if we could have a file or even just a screenshot of your network that would be great.

Cheers,

 

Dave.

Here is the file of the scene

OK so the issue is the rest sop you've got after the dop network has no reference frame, so it's calculating a new rest each frame and hence the swimming textures.

 

If you treat the rest here the same way as you've treated the uv's your problem will be fixed.

 

ie; timeshift and plug it into the second input of the rest sop, this tells the sop to use that input as the rest position overall.  Most of the time you want this to be static (as in this case) but you can also get some cool effects by animating that input, as long as the topology hasn't changed (ie point count...)

 

Hope this helps,

Dave.

That did it, Dave! Thank you very much!
