I'm quite often editing maps for shaders (diffuse, specular, displacement, etc) in photoshop. Whenever i use a new name for the file the changes i made are directly visible in my viewport. However if i overwrite the file, the update in the viewport is not happening. I can bypass the material and re-enable it but somewhere the old texture stays in Houdini's cache.
On file nodes and mdd nodes etc there is a reload file button.
Is there a “reload texture” button somewhere?

Hope this makes sense.

Yes, in the main menu - Render > Update Textures.

Thank you twod, i know about that one, but it does a global reload. This takes quite a lot of time if the scene has a lot of different textures. Isn't there a per texture way?

I don't think there is…
one trick is to change the path, then change it back again…so
/path/to/myTextureFile.rat
change it to
/path/to/myTexture File.rat
then back again

Thanks Arctor, i already tried that trick but it doesn't work here. Me trying to out-smart Houdini this way isn't working, it just re-uses the cached version.

No, there isn't a per-texture reload for GL textures.

Too bad but thanks for clearing it up. Maybe i should post this as a RFE?

I think this has already has a RFE attached. Last I heard from Support was they were working on it getting fixed.
