I think this is more than likely a old issue that has been asked before but I did not see a thread on it.
I am pretty new to rendering in Maya. My habit has been to use texture files applied to default shader materials and in some cases bump maps. Generally I either use a default fractal bump or I use the same image as the texture file but in grey and with contrast adjusted. I only adjust the UV repeats in the placement settings until I get a look that is ok. I am talking things like grass or asphalt-not textures that need careful placement.
In Sketchup for instance I can do roughly the same thing and the textures give no problems with and animated camera but in Maya they flicker, buzz, look like TV static-whatever you want to think of it as-when the camera moves.
This also happened when I used a grass shader I downloaded. I am using Mental Ray but this occurs with Maya software as well. I am not sure if this is because of my rudimentary way of applying textures or what. I imagine there are better ways to apply textures but I just want to spread out a grass texture like a carpet. Can someone suggest a solution or tutorial that will help me understand this issue relatively quickly as I have a quick turn around on this project.
This seems to be a common problem and solutions vary from deleting history, to changing projection settings to baking textures. Not sure which rabbit hole to go down.

Thanks!
