    And the link to the WH:

    The trees you are making do have the .ArPlant information, so go ahead and upload them.

    If you use custom leaves or bark, we will want to upload them again after we make a new version next week which stores the custom images on the tree as well.

      Prior to rendering in Vray, I had to explode the Faceme component twice, then return it to a faceme component. I had to generate a transparency/alpha/clipmap (I use Deep Exploration)to plug into the transparency slot in Vray. This worked fine and the trees rendered well. The process is a bit of a pain, but who can complain about such nice trees for free!

      It would be nice to see an option added to put in a flower map. This would open up the possibility of doing and assortment of flowering shrubs and trees.

        Al,

        Thank you very much for this application. Works great and the trees and the options all work like a charm. Even tested it with other leaves as someone suggested -- having converted them to PNGs.

        Thanks again.

          Al,

          As earthmover stated we (vray users) will still need to generate a alpha/clipmap for these to work. I am not sure how much trouble it would be for the program to export out the associated clipmap at export but it would be a huge time saver.

          Thanks again,
          Scott

            Hi Al,
            Just wanted to get back on the 2D/3D subject.
            As I understand, the treegenerator is actually 3D based by default right?
            So what about the option to have the full 3D tree as output?
            Would be great for us render headz. πŸ‘

            cheers,
            Kwistenbiebel

                  Send me, or upload, a .SKP file or .PNG of a RpTreeMaker tree and a alpha/clipmap of the same tree so I will know what it is you need. Is the clipmap stored in SketchUp anywhere, or separately?

                  We store all the old .PNG files in the RPS_TreeMaker_Images sub-folder of your temporary folder. If we can easily make a clipmap we could store it there as well.

                    Got it working. It's a pretty neat tool. Can you change color? If so, how? This would be very important.

                    Thanks,

                    Huck

                    To change color, you can take the raster images for the leaves or bark, change the color, and save them with a new name.

                    These are stored in:

                    C:\Program Files\Render Plus Systems\RpTreeMaker\Support\Plants

                    in a Bark and a Leaves sub-folder.

                    Here I took the standard leaf, made it yellow, saved it as a new leaf, and used it to render the tree.

                    yellow-leaf.jpg

                    You can create your won bark and leaf images by altering the color of existing images.

                    You will need a paint program which respects the Alpha Channel.

                    (I don't have one, but there is a tool in RpTools which will convert the background color of an image to an alpha channel which I used.)

                      There are methods of obtaining a clipmap from a png using any decent image editor. What you effectively end up with is an alpha-channel image. That is a separate image of the tree, exactly the same size as the png, in which every transparent pixel is represented as black and every opaque one as white.
                      I'm assuming Rick has already worked this out in his image profile ruby in order to generate the path of the vector outlines....but that'll be the encrypted or server-side bit. πŸ˜‰

                        I will try this out (creating full 3D plants) and see if it works and or is practical.

                        However, this may effect the "Free" aspect of RpTreeMaker. I will have to discuss this with the developer, since he includes this product as a tool in his own rendering package (nXt) - which is not free.

                          That will be easy to do - to create a second PNG image.

                          The RpTreeMaker images are not all-on / all-off transparent. the edge pixels are partially transparent.

                          partially-transparent.jpg

                          See how the horizon is partially visible through the pixels at the edge of the leaf. This helps make the tree blend in better at the edges.

                          I presume a clipmap uses gray pixels to represent partial transparency?

                          Also, is there a naming convention which would make these easier for V-ray users to use?

                            I'd imagine that there would need to be a degree of feathering around the outline, Al. A pixelated all-or-nothing outline would be just plain nasty.

                              The sample clipmap Scott sent me does indeed have feathering around the edges:

                                Al, thanks for the fantastic plug-in; you've solved the problem of cloned tree/shrub components.

                                While playing around with it, I noticed it makes the insertion point at the center of the component. This means if you have a lopsided or leaning tree, it's not at the trunk; when orbiting the model, the trunk's location will change. Any chance the program can be modified so that the insertion point is always on the base of the trunk?

                                My avatar is an anachronism.

                                  I might be missing something here, but is there a slider to adjust the taper for the actual trunk object? I am thinking of the giant redwoods or ponderosas out in California- they are hundreds of feet tall and don't have the cute "flare" at the base of the trunk that I can't seem to get rid of.

                                    We're going to do two things.

                                    1. Clip the roots at the ground - right now we make an image which includes roots below the ground. That is useful sometimes, but much too confusing.

                                    2. Create the image (and component) so that the center of the bottom of the trunk is at the center of the image (and component)

                                      Go to 'Trunk'...and use the 'spread' slider

                                      A 3D version sounds attractive but if you look at the way this app can produce leaves [or in 3D, polygons] I would guess that you could come up with 50 and 60 Mb trees [if you could get that far without SU crashing πŸ˜„]

                                        Okay. . .So I am playing with this, and Have created a Dang Ugly tree if I say so myself. When I did Render 1, I didn't see it at all, but then exploded it and it showed up--But as you can see--rectangular shadows.

                                        Any quick tuts on a remedy? I have read thru most of this stuff, and I am a bit confused. (Nothing new there, hehe, but still . . .)RPTRee Test Image.jpg

                                        If I make it look easy...It is probably easy

                                          Dave...youve got me confused now.....how did you explode the tree without seeing it? πŸ˜•
                                          But anyway, there is no point in exploding the tree unless you are using it in a renderer like Podium [in which case the square shadow turns into a realistic shadow after rendering]
                                          At the moment, the trees dont cast shadows in SU....unless exploded....and by doing that you also loose the 'face me' capability.

                                          Oh, and Id loose the roots....looks a bit like one of those plastic Xmas trees πŸ˜„
