Default texture using llSetTexture

Is there a way to tell this child prim via link message that if the specified texture is not in the objects inventory then to display another texture (i.e. DefaultTexture.jpg)?

Right now, if the texture is not in there, then it just gives the error:
Bottom Bar: Couldn't find texture yourTexture

default {
	link_message(integer sender, integer side, string textureKey, key methodName) {
		if (methodName == "setTexture") {
			llSetTexture(textureKey, side);  //if it's not there, then show something else!
		}
	}
}

Use this LSL command to add in a detection step before calling llSetTexture.

You can use llGetInventoryType to check whether the texture exists first using the name....

e.g.

if (llGetInventoryType(textureName) == -1) textureName = "Default Texture";
llSetTexture(textureName, side);

but if you're referring to textures by UUID, why do you care whether they're in the inventory or not? Or is textureKey actually the texture name?

Yep, it's the texture name
I'm logging in to try out your solution. I'll post back in a few. Thanks!!!

Works beautifully hun! Thanks!!
