Warning on render logs: rgba attribute has no alpha component, exporting as RGBA

The warning above happens when my texture maps don't have alphas in the texture maps.

If plug in a procedural node like the maya ramp node into a file nodes default color, the warning goes away.

Working with a large scale of textures i'm wondering if there is something else i could do instead to avoid getting these warning pop up on the render logs.

I use a file node, with a texture plugged in (The texture only had RGB channels), and that connects into Base Color of aiStandard Surface shader.

The warning appears with the same file node structure mentioned above, connected to specular attributes etc.


Wondering what the benefit/difference would be of using the aiImage vs file nodes.

To get this warning, what do I have to connect to what?

With a 3 channel texture, an aiimage node into the input of an aicolorcorrect doesn't give me that warning.

It is, however i'm trying to clean up on warnings to ensure 150+ textures aren't called out in render logs as it adds to the render time.

It's just a warning, and in this case, it's safe to ignore.
