Hey Dillster,
Thank you so much for replying and no worries, hope you had a great Bank Holiday-I totally get it.
I have only just seen this reply so I shall try it out immediately.
Thanks again for all the info and images.
I shall let you know if it works for me.
Felling thankful and hopeful.

Hi guys,
So, I split my model in Zbrush-applied different materials to subtools [Can’t see a way to apply materials to different polygroups when the model is all one thing] . I then Merged the model back into one piece -making sure I had merge uv on. So far so good, feeling excited.
Made sure auto Merge was off and group by materials and took into keyshot. Yay, that worked great.
The downside is that the texture map I need to apply is all wrong.:(
Went back into Zbrush- did Joseph Drust’s technique of exporting a new (holding texture map] over with the model so it recognises the uvs and I can apply my other maps, but now the model is just one thing again and I don’t have the option to apply separate materials.
If only there was a way to save the model with all its separate parts and keep the uvs.
Am I doing this spectacularly wrong?
Can’t see a way to apply materials to different polygroups when the model is all one thing.
Mask the polygroup you want to apply material to, then invert mask so that polygroup isn’t masked and all the others are. Then “Fill Object” to add material only to the intended polygroup.

Don’t send the texture from ZBrush with the mesh. Instead (after adding your materials) you can apply the texture in Keyshot by clicking the Texture icon, locating it and dragging it onto the mesh.
My uvs are all on the same texture map when I apply the texture I don’t understand how to get it to cover the model as a whole when it has seperate parts? As it sees all the different parts and my texture map has all the parts in one place-Am I being really dumb here. Probably.
I didn’t realise your model was in separate parts, I thought it was just one part with several polygroups. In that case you need to apply the texture map in Keyshot to each part, remembering to check that “UV Co-ordinates” is ticked.
Hey Dillster,
My model is one thing in Zbrush, with lots of polygroups, I applied different materials to polygroups.
I send it over to Keyshot and it sees it as different parts so I can apply different materials. 
Brilliant.
My problem now is the texture /normal maps don’t align up.
I cannot get it to line up at all on all the different parts. The texture map wasn’t made in zbrush. That shouldn’t be an issue as before when I took the model in to KS without fiddling with the groups etc the map saw the model as a whole piece and lined up nicely with the uv coordinates…
After much frustration on the Keyshot forum,I have sent a support ticket to Keyshot in the hope that they can point me to where I am going wrong. As soon as I get an answer, I will post here.
Thanks again Dillster and Mealy for all your help.

Dillster,
I tried to line up the maps using uv coordinates on all the parts, not working for me.
Ticket sent to Keyshot support and I will let you know how I get on.
Thanks again for taking the time to help. You are a star.
So, it turns out that I needed the newer version of Keyshot.
Thanks for all your help guys.
