Can anyone look at my results and tell me where I went wrong? I used the fire (fir) tree and followed as best as I could. I am using Vue 4.10-02. Here is the tutorial I was trying to use: Create a fire tree, copy-past it and leave it at the same place. Choose the pasted fire tree in the world browser. Click with your right mouse button in the vegetation window (it's grey for the moment) and choose LOAD A MATERIAL. In the new window, go to FILE - VUE D'ESPRIT - PLANTS - FIRE TREE BRANCH.MAT and click. Now, you see the fire tree leaves in the vegetation window. Double click at it, choose PROCEDURAL COLORS - NEW. Choose white color. In the BUMPS window, choose the NULL function. Click OK. Twist the pasted fire tree gentle (you just need to twist it a very little bit, try out what's the best), then superimpose exactly the trunks of tree 1 and tree 2. (example IMAGE 1) Instead of twisting, you also can raise the pasted fire tree (z=0.2 i.e, thanks to Jean-RenLivenais !). The result is a little different. This permits you to create several aspects of the trees. (example IMAGE 2)
