    so seeing this error in my shadergraph using LWRP,I’m guessing I’ve hit a limit on how many textures I can use in my shader. I’m just staring to work with shaders so my understanding is next to noting but I’ve seen shader that can take 256 textures , how can I use more than 16 textures in my shadergraph,please help

    You’re limited to 16 sampler states per shader, not 16 textures. By default each texture gets its own sampler state, which means you hit the 16 sampler limit after 16 textures. You can work around this by defining a sampler state and reusing it to sample multiple textures. I believe Shader Graph has the Sampler State Node for this. However that only gets you to 128 textures. The real solution to get past that is using a texture array, which is how those shaders that advertise 256 textures work. And those shaders really have a limit of 256 texture sets, which includes the diffuse, normal, and smoothness textures. A texture array is a special kind of texture which the shader sees as a single texture, and the 256 limit has more to do with the way the texture stores which texture layer to sample. Really you could have 65536 textures in a single shader by using 128 texture arrays with 512 layers each, but that’s overkill.

    If all you need is to get a few more textures, a shared sampler state is the easier option.

    Thanks for the info, looks like I will need to use a texture array. Have you done texture arrays in shadergraph I would know where to start, so I need to create a texture array or can I just plug textures in as I go

    Unity's editor doesn't help with creating texture arrays at all. You have to construct them entirely on your own from script, or download something from the asset store which can help. Once they've been setup, they can be plugged into a sample 2d array node.

    Hi there, I have the same problem but I am using ASE. I am doing a terrain shader and I just need a few more than 16 textures, 20 in fact. Is there an equivalent of this Sampler State Node in Amplify?

    Ive used a textureArray in Amplify, seems like this is what you need. I used over 50 textures that way in a single sampler

    Thanks Bgolus, using the Sampler State node worked perfectly to have more than 16 textures at once in a shader. Now is it optimized? Time will tell... :)

    @Horus_Sungod42 How did you use SamplerState node? Just attaching its output to sampler input ok?

    @Horus_Sungod42 I don´t know how using the samplerState node resolve this issue. I´m using 12 textures and one SamplerState node and Unity is having problem to render preview for material. You can post the schemas of how you work with this issue? Thanks

    I'm getting this error on Shaders made by Unity URP, only while building, which is extremely weird (Unity 2021.2.7f1 - URP 12.1.2):

    upload_2022-4-12_16-35-45.png


    Does anybody know why? And the solution to it? The build somehow does get completed but the errors worry me a great deal.

    I have exact same errors when I build my project or my addressables groups. I am using Unity 2021.2.14.

    I'm not 100% sure about this, but if you work for Unity perhaps you have a way of testing this.

    We managed to build the game by removing all the shaders (we added them all into a Shader Variant) and then build again with all the shaders.

    It makes no sense but we figure (because we tried this in a couple of PCs) it's something related to a Unity cache bug (not project cache because we re-generated the project like 5 times and even updated it).


    That's it.

    Our weird process was like:

    Build with all the shaders - Fail.
    Build with 0 shaders - Success.
    Build with all the shaders - Success.


    ¯\_(ツ)_/¯

    Same - got it after upgrading to 2021.3.2 looks like we got LTS release with a breaking bug... I think if the tech bubble bursts we might lose Unity altogether if they keep working like this.

    How do you build without the shaders? I do not understand what you did

    I'm also having this problem, a shader I've used for a long time keeps getting this error suddenly. I thought it was an amplify error.

    It appears to be an actual Unity error, and the temporary workaround until a proper fix from them was to move URP to the Packages folder and edit all the ShaderGraph shaders and leave them empty (helps with project size at least...).

    I'm getting this with 2021.3.7f1
    Built my Addressables Groups for the game yesterday and everything was fine. This just suddenly popped up today after I made some script changes (unrelated to shaders).

    If I delete 'library' this works initially, then after some time the error comes back again. What's going on? This is preventing building for Android.

    I am also having this issue with 2021.3.7f1.

    @Unity, can we get an answer on this?

    Hi!
    It would be great if someone filed a bug report detailing the inconsistent behaviour.
    Thanks!

    Happened to me today in a URP project on 2021 LTS, after installing Unity Terrain tools, Removing the Unity terrain tools also removed the error.
    Lesson, don't use unity asset addons in Unity..

    Thanks for the input, it didn't work for me, so i tried also to delete TerrainTools folder under the Library folder in the project folder and it worked for me

    Hi, this is the full report of the bug knowing that i'm using the 2021.3.15f1 and using a texture from SampleTerrain Asset in a Terrain object (i've tried to use only One Texture but the problem stays):

    No one have a solution?
    what i have see if when i do build, works, if i do build & run then it breaks

    I'm getting

    Shader error in 'Tobyfredson/Detailed Map Coverage Moss_URP': maximum ps_5_0 sampler
    register
    index (16) exceeded at line 331 (on gles3)

    On URP build for no reason, I don't even have 4 texture samplers in my shader, doesn't make any sense the same for my other shaders!

    Is there a performance cost to reusing the same sampler multiple times? Why reasons would there be not to use a single sampler for a whole shader?

    GPUs can use multiple samplers in parallel to hide latency in the shader. If you use a single sampler the texture reads can end up being serialized.

    For example, when using separate samplers for diffuse and normal, the shader can request data from both textures at the same time. If you use the same sampler, it will first read the diffuse then read the normal, taking double the time.

    As Neto suggested above if your shader is small don't bother as you will increase complexity
    if it's a large shader lots of samples ok as you get past a certain point you gain by using sampler states

    common practice
    when you use sampler state macros in a shader you should have some SS macro assigned to every sample within that shader all or nothing. You should not use a single sampler state for everything as you can break the mip chain crossing in the fragment stages. i suggest think of it in 3 SS groups and you should be safe.

    -- base color aka main tex can share with anything such as specular, smoothness, ............... except the below:

    -- normal maps should be in its own SS group

    --- anything that uses vertex offset in its own group

    cheers
