Hi Dwaik - thanks for that but that isn't the problem I'm afraid. The textures are loaded at the beginning with the model - as I said they do appear in the assets list at step 2 and they do appear in the runtime visualisation. This is what confuses me - the textures do seem to be there but just not making it into the executable. I have even tried dragging the textures in again at step 2as you suggest but no joy!

Additionally - the textures for the model used to load fine and all was great. I then made a few small alterations to the model (in 3Ds Max) and re-exported and lo and behold the problem started.

I am just going to start running through exporting bits of the model at a time but hoped that someone may have come across something similar before. My betting is that it is something else simple that I have overlooked.

Cheers

Dave
