The leading technology for Virtual Texturing in Unity
Amplify Texture is our proprietary technology that allows real-time applications to present scenes without any sort of texture limitations imposed by GPU memory limits. Virtual texturing enables up to 1 TB of unique texture data per-scene, or the equivalent to a resolution of 5 Km^2 at 1 texel/cm, without compromising performance. Our use of high-quality, more efficient texture compression will reduce your build size significantly. This is your chance to build unique, beautiful worlds in Unity.
Amplify Texture 2 is Coming!
Virtual Texturing means freedom!
At Amplify Creations we strive for perfection, in this case we wanted the technology to be seamless.
What is Amplify Texture? In short, it’s Virtual Texturing for the masses. We decided to start our adventure by adapting our technology, with great results, to Unity3d, one of the most popular 3d engines widely available, now with over 2 Million Registered Developers.
Although Amplify Texture is highly portable, we will continue to explore future versions and enhancements for the large Unity Community.
Understanding Virtual Texturing and why you want it
How does it work?
Virtual texturing works by slicing all your textures into smaller tiles (or pages) and store them in large files optimized for streaming. At runtime, the view from your camera is analyzed and visible tiles are requested and streamed from disk in the background. Because you only see a portion of the scene with full level-of-detail at any given time, the system is able to balance hardware resources very efficiently. Very large scenes and wide area views also work great, by streaming the data with our Virtual Texturing technology, there won’t be any impact in performance or compromise in the visual accuracy.
This would be impossible without Virtual Texturing technology, the texture data simply would not fit on your GPU memory.
Efficient compression! With standard gpu compression you would normally get a 6:1 compression ration, using our technology you might go up to 15:1 without any noticeable quality loss. You might even take compression further for lesser detailed virtual textures with ratios up to, or beyond, 30:1.
This will directly have an effect on the size of your virtual textures, resulting smaller and more manageable files.
How do you use it? To use this plug-in and take advantage of virtual texturing you don’t have to change the way you assemble your scenes. Amplify adapts to your workflow, and not the other way around. There’s is no need to setup UVs any differently. Amplify replicates all your existing texturing using virtual textures, including repeat/tiled surfaces. While you edit your scene, the system incrementally builds the virtual texture so you can instantly preview the results right there in the editor. We invested time and effort trying to make the transition to virtual texturing as simple and transparent as possible. The following video demonstrates the typical Amplify workflow. As you can see, the main difference from the regular workflow involves selecting an Amplify shader for any material or surface eligible for virtualization.
Virtual Texturing in Action
We’ve built a tech demo to demonstrate an extreme case in which we used roughly 10 GB of raw texture data, most of it uniquely painted, in a relatively small scene. If you look closely, at certain viewpoints you can actually see most of the textures in the scene without it affecting performance.
Did you notice anything, Textures popping into the scene or weird texture swaps?
Exactly! Even though the scene is using 10GB of texture data, the transitions are seamless. You work as you always did and the technology takes care of all the backend work, completely invisible.
Just remember this: The only limit is your imagination.
Forget textures with a maximum size of 4096 pixels, that will soon be a thing of the past.
