Blender Trees?

[Blalack77]

I created some trees in Blender.  The first one was perfect in the Blender preview and I exported, then it was near perfect in Terragen 2.  But, then I made a second tree in Blender.  It also looked perfect in the preview but, when I got into Terragen and made a population their colors were bad wrong; like the leaves were brownish instead of green. I checked all the settings and they were the same as the first tree.  But, what could this be?  What settings do I need with a program like Blender?  Do I need to create the object with environment lighting and light sources and such or just make the object plain by itself?  Any other tips?

Heres a visual on the problem...

And this is what the render looked like in Blender:
 

So I'm not sure what goes wrong between Blender and Terragen. I don't know if it's a simple lighting problem or a setting or some complex texturing. Any thoughts?

Looks like Terragen can no longer find the image and mask files.  Highlight the tree's object name and select the Surface Shaders Tab > "Go to Parts Shader 01" > "edit Internal network".  For  each of the Red node entries for your tree,  click the "Color Tab" and then the folder icon for "color image".  Navigate to your image library and load the image file.  Then in the "Opacity Tab" select the folder icon for "Opacity image" and load the image mask.  Now re-render your image. If the tree looks good , you can save it as a TGO file for future use.

Like he said...

Remap your textures in Terragen and the save as a TGO.

How do you save as a TGO from Terragen?  I think I'm on to something.  I tweaked with some of the texture settings within Terragen and now some of the tree population is looking better, but some are still dark...This is even weirder now.

If anyone is seeing this:  I figured out how to save the file but I'm still having some gnarly problems.  I have 3 sets of leaves for my tree.  One set is bright green and I'm guessing the other two are dark green-black.  The picture files are roughly the same lighting and color and as you see from the Blender render they looked fine at some point.  But I've been tweaking the settings inside Terragen and some of the leaves brightened up and some didn't.  I've tried a variety of settings and with this picture all the textures have the same settings yet they look different in render view.

right click the object in the node pane and a drop down of options appears...select Save Object File>a requester comes up with your current object name .obj...get rid of the .obj, and hit Save as it's changed to Terragen Object Type in the object types automatically....that's all...you can only save single objects tho, not populations. I've saved groupings I made(non population style) and saved them as clip files cuz sometimes I want a group but that's the saving options....

not understanding the problem, maybe having  the model with all the maps and your scene setup I could help...

[Blalack77]

I'm not 100% exactly sure what you want.  If you're talking about the actual object file, I think it's too big to attach.  I have everything, but what exactly were you wanting?

Maybe this will help some.

In the node network, find your object (tree, either .obj or .tgo) and right click it.  Select "Internal Network."  Now right click "Internal Network" again.  You should see your "Parts shader 01" (unless you renamed it.) Right click it and select "Internal Network" again.

Now you should see each of the materials you assigned to your mode.  They will be labeled something like this:
     "material_1 shader" attached to "material_1"
     "material_2 shader" attached to "material_2"

Now right click one of the shaders and select "Settings."  You should see a panel open where you can verify/assign/adjust your texture image maps.

It looks like one leaf image is projected onto the whole population.

I think you should definitely try passing the model through Poseray. Hopefully this thread isn't yet out of date: http://www.planetside.co.uk/forums/index.php?topic=9798.0
