Any way to acheive shadows like this ?

[spring kestrel]

I know there is no way to acheive Point filtered shadows in HDRP using the default unity shaders/shadows, how could i go about making something to have pixelated shadows like the image ? Would i need to change the object's shaders ? or something about the lights ? or the render pipeline code itself ? i just need indications on where i should look in the first place

I've answered you in the dicussions thread.

(here for reference)

[spring kestrel]

thank you ^^"

[spring kestrel]

there is in fact a way :D
its not antialisaed like the picture but it works anyway

[spring kestrel]

answer is in there

[thick sphinx]

I've answered again on discussions ^^
I think there might be a solution to have a "pixelated filtered shadow", by keeping the PCF_Tent_3x3 method, but use a point sampler state inside it.

[spring kestrel]

In discussions again
Couldnt make it work :(
all the shadows are broken

[thick sphinx]

I answered again, with actually trying it on my side and gave you a solution.
I think this is what you want now :

[spring kestrel]

This is perfect, thank you

[spring kestrel]

I know this is solved, but any idea how to do it in URP ? i cant find a file that defines what filtering to use

i assume it is somewhere in this one ? https://github.com/Unity-Technologies/Graphics/blob/master/Packages/com.unity.render-pipelines.universal/ShaderLibrary/Shadows.hlsl

[thick sphinx]

Yes, from L234 to L340
You can see the individual filtering functions, and the global sample calls.

Did you try to disable soft shadows in the URP asset ?

[spring kestrel]

i did turn off soft shadows, but they are still bilinearly filtered and not point filtered

[spring kestrel]

yeah it seems to be the place to change something but i dont really know what to change-
Doesnt seem as simple as in HDRP

[thick sphinx]

L332 is where the shadow is sampled when softshadows are off.
I guess you just have to change the sampler state, like for HDRP.

[spring kestrel]

i test it and i come back

[spring kestrel]

huh
I added a step 0.5 around the function but its not exactly what i expected

attenuation = step(0.5, real(SAMPLE_TEXTURE2D_SHADOW(ShadowMap, sampler_ShadowMap, shadowCoord.xyz)));

Im not sure if i can change the sampler state, i assumed i couldnt like in hdrp but Im gonna try anyways
Sorry if im really slow its a lot of trial and error lol

[spring kestrel]

got it !
ill be honest i had to use chatgpt for help but it did figure it out after a lot of handholding damn

basically, replace line 332 with

        attenuation = shadowCoord.z >= shadowDepth ? 1.0 : 0.0;```

[spring kestrel]

Thank you for helping find the line btw, you're an angel!

Minecraft's shadows are not exactly point filtered
They are soft but snapped to world coordinate grid, or texture UVs (times two) like this, no difference if the world is a voxel grid

[spring kestrel]

Oh damn
I might try doing it in shadergraph, it looks cool
Thank you!
