Hi ezanih
I did put a link on your thread to uvs check it out it does explain how to use uv projection to get the best results, you have to understand the work flow between maya and zbrush to get the best out of them, say you have a good low poly base mesh that only needs fine detail like skin porse what you do is first you create UVs in maya (at a later date you could use zbrush UVs) then export to zbrush, in zbrush you divide the mesh to level 6 then create the porses on the model you then move down to level 1 and create your bump map then export your mesh plus the bump map to maya, sorry have not create explosions but should be some thing free on the net.............hope you are well.........dave
