Many thanks Bobby, much appreciated. With the weekend coming up I will attempt Dune's instructions
Have in the meantime softened the water along Hannes suggestion and for my own testing imported a figure from Poser Pro 11 which is/was my main interest.
The results are instructive as you can see from the zoom, very rough for some reason...
Looking at the MTL output from Poser shows only a limited subset of the shader settings have been exported (Poser problem) and I need to look at and explore this.
Manually updating the MTL file with more refined settings, e.g., transparency, reflection, colour, and reimporting doesn't seem to improve textures however, see close up of the transparency and reflective settings on the glasses in the zoom.
Also trying to refine individual component textures in T4 resulted in my first ever crashes.
Also, each change to a setting took 45 secs to make, which I assume is because T4 is trying to live update (?)
I've seen some results by Hannes (I seem to remember) that looked very promising, but am stymied owing to an underpowered machine, which doesn't lend itself to making those kind of changes
Now understand why most of the figures I've seen in T4 renders tend to be small.
Anyway, for those interested in such things I enclose a second render with tweaked water and a Poser import.
If anyone would like a figure of any sort, to play around with just let me know and I can upload a zip with all associated textures in the same folder. Small gallery at
