    deform instance geometry along path

    Instead of cutting could you use the cropping tool in the "bitmap parameters" tab of your map in the material editor ? Then you could just apply the atlas like a regular bitmap onto the native GrowFX leaf mesh. I am not sure if this is exactly what you need, but it would allow you avoid using instances. I am not really sure if my method is the correct way, but it works for me. UPDATE: Try rotating the pivot of your instance object. It looks like GrowFX deforms instances along the z axis. On a flat object there is no z info. You have to align the z to the long axis (the one you want to bend). In the image on the original post it looks like the z is aligned to the long axis, unless the leaves were created flat and then rotated into position. This wouldn't change the pivot and would give the above result of a flat non conforming leaf. also, make sure that you cut some segments in your geometry to allow for the bend. Hope it helps !
  2. Hi Danilo Its hard to say without looking at the file. You could try checking the "turn off central edges" in the mesh builder panel for your leaves, and making the segment distance (modifier panel), and the minimum face size (modelling panel) .This will bring your poly count down, which might help. In the main menu under preferences you could try turning off "meta mesh" universally. If you model works properly with with this option checked then the problem is occuring when your meta mesh is being built. It's hard to say without more information, could you do a screen capture with all three tabs expanded? That would allow me to see what your settings are and hopefully give you a better answer.

    Cylinder mesh thickness

    Thanks sajith ! you are totally right, thanks for the correction You branch structure looks much better!

    Cylinder mesh thickness

    It looks like your graph is just dropping off too soon. Your initial radious is set at 2mm so at thirty (the left hand side of your graph) your branch would be 60mm tapering down to about 8mm for your first branch. Your min is 3mm so you get a taper from 8mm to 3mm at around half the second level. This isn't very perceptable. The remainder of your levels would be 3mm (your minimum). What I would do is Input the largest radius the branch would be into the radius dialog. After you have done this just set your left side of the graph at 1 (the largest the branch would be) and the right hand side at around .5 or .6. Over the course of three levels this would get you down to your minimum diameter smoothly. so if you have a 50mm branch, at the first level at .5 on the right hand side of your graph then you would have a 6.25mm branch on the third level. This should be pretty smooth. Hope it helps

    GrowFX + Forest Pack

    You will definitely save RAM, I am not sure about hard drive space. It depends upon how Forest pack treats your animated proxies. For stills, I did a test and Forest pack objects made with .gfx files do appear smaller than polygon meshes, but I could have misread. I think the .gfx file is just a set of instructions to build a mesh, that is why it is so small. The actual mesh produced (which is probably what Forest Pack scatters) is still pretty big. I have been using the combination of these two plugins for a long time and together they have saved me a ton of time.

    Angle Axis in Leaves Mesh Modifier

    Could you use the vector orientation modifier with y axis at 100% ?

    Get Fruit To Hang Properly

    Hi Joel, You could make a small path connecting the fruit to the tree and apply a large downwards vector direction to it. You could also try the hard bend modifier. Hope it helps

    Multithreading - Any updates?

    Hi Mugga A few things I do to make trees more manageable. 1. In the "direction modifiers" panel, make the "steps" larger. Default is 1" use the largest step you can without sacrificing quality. 2. In the "mesh builders" panel change your "face size" again, make this as large as you can without sacrificing quality. 3. In the "mesh builders" for "leaves mesh" turn on "without central edges" Also, turning off the leaf and twig paths like you said you were doing is a big help. If your larger branches look correct (as few intersections as possible) your twigs and leaves should be fine. hope it helps!
  11. Its been a while, but I think I remember not caching within GFX. The Grow FX model was just used to generate the point cache file.

    Mesh Anchors

    that is a really neat feature! I am not sure how you would accomplish something like this in GrowFX natively. You might be able to model parent branch/plane and child twig/plane's manually then apply them to your tree as a reference object. Interesting problem. I am not a developer but I will play with this and re post. Thanks!

    Self shadowing

    Hi Macker, As far as I know there isn't a way to do this efficiently with modifiers. In my experience you just have to avoid intersections of the branches within the first few paths while your modelling. If your initial paths don't intersect then your later ones shouldn't as well. I'm sorry its not a very good answer. Self intersection and self shadowing are something I bear in mind when modelling,but there isn't an automated way to avoid them.

    Proper documentation

    Hi viniciuspaciello, The manual can be found here, https://exlevel.com/download/ It is about halfway down the page. It covers every button and is a pretty quick read. Hope it helps
