So Carlos said he was having problems getting the displacement map for the iceberg working properly. I helped him set up the correct process in class, but the result was not what we wanted, as there were seams showing through and it did not look good. I said I would give it a try myself at home, as I thought there were a few things I could try. So I UV mapped the low res iceberg properly to ensure that it would not give any bad seams or cuts through the displacement. I then created the map using maya, using the transfer maps method.
I tried twice but each time the results were not good, I had to go back and check the search envelope to make sure it was not the reason for the displacement looking like it got cut off, the second time I made sure it was big enough but still it came out badly. I referred to my displacement map notes I had made whilst watching tutorials before, I set up the approximation for the mesh and then started tweaking the settings but alas...I could not get a better result. So it looks like the high res maybe the only option for the final shots...I will inform the group and see what Andy, the director says about this.
I personally feel annoyed as I have had lots of experience with displacement maps and it seems there are always issues. I tried the best method and settings but still not joy..Guess this is all part of the learning process.
