Hi Chirone. The example in the post was just a quick play I had before I went out last week. I have the scene saved but I changed something which I can't remember now and Im not getting the same results as in the picture. I've just tried to recreate it from scratch, but Im getting different results entirely.

Since I first posted this thread Ive had a little play with a couple of other displacement tests. I don't think I quite understood when I did the one in the pictures in my first posts that you create the approximation node for the object. I think I thought you created for the renderer, if you see what I mean, so it's possible I just didn't have the object selected when I created the approximation node.

As I've understand it from google searching, the option to go for is the subdiv option, then select the distance/length/angle option. That seems to be the majority options people set from the seaches I've done. But it's confusing. I don't really understand what all the different options for the approx node do, and I seem to get different results each time, even when I'm pretty sure I'm setting up my object i.e, basic poly cube at the origin, and my material, the same way.

Id like to feel confident I can create some nice displacement cause remember when I worked with source engine for a bit? I made those guns? A comment I got from an ex-tutor of mine, was that I should learn how to do displacement mapping, to add the detail to low poly objects. I tried a brief experiment with a flamethrower model I made for the mod, but the results were pretty funny, the whole low res ballooning thing. Gotta rush to work now. I shall try and add some more useful information to the discussion later on!
