Hi there!
I also tried several things with the old xfrog obj. And I also used your tut Helen, but I wasn´t 100% successful. Just let me tell you what I did...
I imported the purple leaved plum (prunus cersifera nigra) obj into wings3d.
Then I followed the instructions in the tutorial.
I selected the trunk, the leaves, and strangely you were able to select two different types of branches too.
I saved them as new material and assigned a color.
Then I saved everything as new obj.
I got the obj and the mtl file and tried to import it into Terragen, what worked without problems.
I figured out that the mtl-file hadn´t the textures included, meaning, the saved images of trunk and leaves. I changed the png and rgb files into jpg files and put them into the same folder as the obj and mtl file. After I added the location of the image-files to the mtl-file, they all loaded in Terragen without problems, I found them all in the multishader.
So far so good.
I got a tree after the first render, but what I got wasn´t much satisfying. Somehow the leaves were green, they should be plum-colored like the image file of the leaves. Well, as well I couldn´t see any leaf-texture on the leaves. They were leave-shaped but had a bright-green colour - and now comes the clou. In the middle of the bright-green shapes leaves, there are smaller, dark-green leaves with texture....
At least there is some texture, but again in the wrong colour...and why do they have this strange bright-green border (also leaf-shaped, but no text). It´a real riddle to me. Whatever I did with the image files, and the alhpa-image files...nothing seem to work.
The trunk as well is very square-cut and there´s also not the right texture on it.
I don´t have any clue where the problem is....maybe someone has some idea what else I can try to get a natural looking tree?
Maybe I did something wrong in the wings3d program? I´m not sure...cause when I added the colour in the program it seemed to keep exact this colour in Terragen...and I wasn´t able to change that (as pointed out above).
Maybe, when I´m home, I can add a picture so you can see more clearly what I was referring to...it´s always difficult to describe such things....a picture often says more than thousand words.
Maybe you have to add the right textures in 3dwings?
And what else wondered me a bit, when I changed the images, first the png: I followed again the instructions and in the end the leaf was white (only the shape remained) and then the background was all black. I saved it as jpg and was done. With the rgb file it was more difficult, because there wasn´t only the leaf, there was some strange texture in the background. I considered that to be the alpha-channel picture, cause when I finally succeeded in changing it the same way like the png, and wanted to save it as jpg, the program said that with saving the alpha-channel will be lost.
I also saved the original pictures as jpg and with the rgb it was again the same: the alpha-channel will be lost.
So I´m not sure if this has something to do with it. Any suggestions about that?
Hell, I hope I´m someday able to get these things right.....
Thanks in advance for ANY help on that...I´m really at a loss at the moment....
Aenea
