Using `uv6` buffer in mat plugins, when using a texture throws a redefinition error

This PG

throws an error when I try to use uv6 w/ a texture applied
image

so I thought I’d just regex that out if it was being declared other than me declaring it, like so

        "!in vec2 uv6;": "",
        "!attribute vec2 uv6;": "",

but that doesn’t work : /

Is there a way I can get rid of this and use a vert buffer to carry my extra data?

also is uv4, uv5, and uv6 smth that’s being used for smth important internally? cuz I wanted to have my own extra data in it : O

tysm! : )

Does it need to be name uv6 ? I believe any name is fine as long as it’s not already in use

you’re right! for instanced buffer I can use any name : )

but for regular vertex buffers, can I use any name as well?

like in this PG

afaik I’m limited to,

indices, positions, normals, tangents, uvs, uvs2, uvs3, uvs4, uvs5, uvs6, colors, matricesIndices, matricesWeights, matricesIndicesExtra, matricesWeightsExtra

yeah?

In this example from the documentation, a new vertex data texIndices is created, filled and used in the vertex shader and forwarded to the fragment.
