texblend or visible for multiple textures

[vizmaster]

Is it a single texture you are trying to make dynamic?
Are you showing a movie?
Is it a 3D world that you are trying to navigate pass this large texture?

At 3K you may be hitting the hardware limits of the graphics card. Most like 512,1024,2048 squares. In my reading I noticed that Vizard does handle odd shaped textures as well.

What is the frame rate 30fps or 60fps?

I have enclosed my scripts for tiling and displaying very large images. The displaying of an image is started by a mail event that includes a filename to display. Maybe these will spawn an idea for you.
