Unable to draw on Custom Shader Graph Shader with "Paint Texture" on the Terrain

Hi y’all

So recently I made a custom triplanar shader for my terrain, so the ground and walls have different textures. It looks great so far, but I’m unable to draw on it. I have tried drawing on this a lot with different plain textures I have:

But whenever I change the shader to the built-in “TerrainLit” material I am able to draw on it no problem (see image). Actually, the drawing I do on the above terrain will show up when I change to the TerrainLit material.

Any idea why this would be? The custome shader I once again made in shader graphs, unsure if that would matter. I also get this notification with the custom shader

Could that be part of it? I don’t think I need a shader which needs tangent geometry on the terrain, but I’m unsure how to remove those. I’m extremely new to shaders, and the terrain tool, so any help is appreciated.

I’ve also done all the answers I’ve found on google to no success. I’ve restarted my computer, changed the layout to default, and a couple other things.

I’m also using Unity 2019.4.0f1 Personal and the preview Terrain Tool (I started using it in the hope that it would fix my problem).

Thanks!
