odd colors on landscape

[Bobreg]

Hi,
I need about 4 levels of materials Dirt - Stone - Gravel - Grass and I also need to make up those materials by using a lerp between two textures. add to that the normal textures and my landscape or terrain have about 16 to 18 textures in them(1024 x1024) pngs. As I paint on the layers I get to a point (usually at the last layer) where large chunks of the terrain go odd colored on me. Is it my computer or the engine or... ??
Is there any way around getting those odd colored patches on landscape without loosing detail?
Thank you.
Bob

Do you have a picture possibly? if its the first then I believe that means you have a material that has too many instructions or is too complex.

Also try breaking up that chunk of the landscape and see if it corrects at all.

Thank you.
The colors are sort of light ... green yellow blue red. I understand that I may be pushing to complexity but I was hoping to find some current guidelines or maybe even a workaround.

Post a screenshot of your material layout so we can better assess your setup.

This is the first in 4 shots of the terrain issue details. Is this what you need?

yea I can see in your 3rd shot the landscape in the background. When it turns all funky color like that then you have made the landscape to complex. I would suggest by looking at your biggest instruction material and see if you can simplify it in anyway.

Thank you.
I wish that I didn't have to simplify if more than it already is
