How to pick texture from texture2darray shader in Unity?
I want something that mimics all the same functionality as the Standard shader, but uses Vector3 in place of Vector2 for the UVs so the Z of the UV can be used to pick the texture from the Texture2DArray. I’m using mesh.SetUVs (0, List (…)) to pass in the 3D UVs.
Why do we need a texture array in Unity?
From the shader side, they are treated as a single resource, and sampling them needs an extra coordinate that indicates which array element to sample from. Typically texture arrays are useful as an alternative for texture atlases, or in other cases where objects use a set of same-sized textures (e.g. terrains).
Can a 3D texture be imported into unity?
Unity doesn’t support directly importing 3D textures, only constructing them from script, so if you have something that’s doing that it’s not an official Unity thing. But there’s no reason why a 3D texture couldn’t be any format Unity currently supports for 2D textures, it just requires modifying the asset when it’s being built from script.
Is there import pipeline for texture arrays in Unity?
Currently in Unity texture arrays do not have an import pipeline for them, and must be created from code, either at runtime or in editor scripts. Using Graphics.CopyTexture is useful for fast copying of pixel data from regular 2D textures into elements of a texture array.
Why is my texture2darray bound as a render target?
So the problem was that my Texture2DArray was still bound as a render target as I tried to set it as a resource in the compute shader. before using CSSetShaderResources ().
How to reject a sample in texture2darray?
Samples a texture, using a comparison value to reject samples. Samples a texture (mipmap level 0 only), using a comparison value to reject samples. Samples a texture using a gradient to influence the way the sample location is calculated. Samples a texture on the specified mipmap level.
How to create a texture2darray in C + +?
I first prepare a set of “render slots” by creating a Texture2DArray using CreateTexture2D with texArrayDesc.ArraySize = numRenderSlots:
