Hi guys ! I find a way to render every obj with the ptx image. Now I'm trying to understand why and how I can have the same look has what did doubleailes (http://guerillarender.com/forum/viewtopic.php?id=1270) especial for the palm tree. I wonder if it's because it's using xgen to render the palm tree leaves. But has I can see from his image is that there are two types of palm tree (the light green leaves are why i rendered) and the other palm trees have many details onto the leaves so has I said it might be a xgen stuff so I'm digging on that !
