Practical Tips for Optimizing Ray Tracing

Nvidia

This starts from mesh instance selection and their data. This starts from mesh instance selection and their data processing towards optimized tracing and shading of every hit that you encounter. Parallel mesh processing for instance data generation. Each instance alone requires 64 bytes of memory. Batched vertex data processing.

While this process is ongoing, we'll keep releasing alpha builds so here's 4.0 This alpha doesn't include official builds with.NET 6 support yet, as we still have more work to do to enable this. For users of previous alphas, we don't always have compatibility code to ease transition. alpha builds.

Creating a See-Through | X-Ray Effect In Unity – Shader Tutorial

Awesome Tuts

What Is a Shader? Since the main premise of this effect is going to be a shader, we’ll start with explaining what a shader is. A shader is a script where you write code that determines how the colors will be rendered based on various scenarios like lighting and material configuration.

How to write Shaders in Unity using HLSL

Febucci

Shaders are used to create many effects, like “water”, “fire” and more. In order to understand them and become a wizard/witch, we have to learn a bit about meshes first. A mesh is made (usually!) You can see the mesh as the structure of your object, built by combining its triangles together. Shaders Theory.

Practical Use of Render Textures

The Knights of Unity

For shaders, I used Amplify Shader Editor to add some visual effects on top of the render texture. Then I’ve put the recorded render texture to a Standard Shader. On top of this, I added another mesh with custom shader, this time, for refraction. And the outcome of the shader looks like this: And that’s it.

Best Practices for Using NVIDIA RTX Ray Tracing (Updated)

Nvidia

Flagging instances or geometries as opaque allows uninterrupted hardware intersection search and prevents invocation of the any-hit shader. Enable the use of any-hit shaders only for those geometries that need it; for example, to do alpha testing. Consider alpha testing instead of blending. Do this whenever possible.
