Hi,
I try to achieve the following:
Given a Texture2DArray with different textures I want to draw a specific one. As I’ve done it without shader graph I set
uv0[index] = new Vector3(uvPosition.x, uvPosition.y, textureArrayIndex);
and use uv.xy as real uv coordinates and uv.z as my index for choosing the Texture out of Texture2DArray.
Somehow I do not get it to work with shader graph.
I use this layout:
It somehow does not pick the correct index but uses some other (constant) index.
I have a functioning workaround using another uv channel, but I suppose it should work as I’ve done above, right?
Here is my work-around using uv2 only for picking the correct index:
uvs[index] = new Vector2(uvPosition.x, uvPosition.y);
uvs2[index] = new Vector2(textureArrayIndex,0);
With a graph like this:
So, am I doing it wrong or is there a bug?
