I have point attribute and I want use it to set different texture for each object. Point attribute is named frame and it's a number between 1 and 10. Files are named "code (1).png", "code (2).png", "code (3).png".... Ussualy to pass attribute to material network I use RSUserDataColor node, but I'm not sure how to pass that value to as a string to texture field.
Filename now looks like this:
$HIP/images/code ($F).png
But instead of $F it should use point attribute named frame.
Please help!

Personally I'd just construct the texture paths using a wrangle in SOPs, save that as a string attrib on the geo then read that into your shader.

But how to read that into the shader. RS texture node doesn't have Filename input.

I haven't used RS in a while but pretty sure RS has it's own node for reading in images. RSImage or RSTexture or something. Isn't TextureSampler a native Houdini node? If so, you should stick to RS nodes.

If the RS image node doesn't have a plug for filename then I'm sorry but I don't have a good answer off the top of my head.

I found solution. So you can pass texture name value with material node. And in the material network add filename input and connect it with the rs texture filename.

Or you use a RS shader switch. feed in all the textures with texture nodes. Then use an integer point attribute to switch between them.

You can also use the rsUserDataString connected to the Redshift OSL Texture node(From Github).
