Unwanted "Smoke" texture being substituted

I didn't know whether to post this to "Design and Textures" or "Scripting", and it could also be considered a "Technical Issue"...

I have a script that is setting many primitive params, but intermittently, when setting the texture, the "Smoke" texture that comes in the default Library is being used instead. There is NO place in the script that I address the "Smoke" texture, either by name or by UUID.

Is this a "default" texture that is used when lag is bad? Or, is there another reason "Smoke" is being used?

Thank you.

This can happen if you pass NULL_KEY as the texture for llSetTexture or a PRIM_TEXTURE setting for llSetPrimitiveParams(). I think it might also happen for an invalid key. Is it possible that some circumstances are causing you to use bad data for your parameters?

This should not be happening, but what "should" and what "does" happen are completely separate.

Time to have the script report out all the keys it thinks its using, and see what is happening. Thanks for the information -- it gives me a place to start looking.
