Hi

I’m trying to make a maritime pine tree 3d object from a picture.
So far I have my tree ready to get its textures.
I have a really basic problem which is to select the foliage part and apply the texture and then to select only the the tree trunk and
apply the corresponding texture.
How can I select those different parts independently?

Thanks in advance

What application are you modelling the tree in?

After you complete your model, the next step is to UV Map it, so that DAZ Studio knows where to apply the textures to.  It involves using the built in UV Mapper for the modeller you are using, or the (free) UV Mapper application or similar (Blender?).  Once the UVs have been laid out, you create a template from the OBJ file, and take it into a paint program and apply the texture to it.

I Hexagon, for example, you can create Shading Domains, which is a way of selecting polygon groups, and applying a seperate texture to them.  These shading domains will appear in the DS Surfaces pane.  You could try that?

Another way is to use the Polygon Group Editor inside DAZ Studio, and assign a name to any group of polygons, and then apply the texture in the Surfaces pane.

UV Mapping will give far better results for most things.

Sorry I’m using Bryce 7

In that case, I will leave to a Bryce user to help you.

Chohole will know what to tell you I’m sure.

Is this a tree from the tree lab.

If so

I select the tree

2 selct edit from the attributes screen

3 select edit(next to material) for the leaves   then go to the material lab and select leaves

4 go back to the edit screen select edit material for trunk   THen select a trunk material from the trunks mats.

Hi Chohole, no it’s a tree I made myself from a picture I found on the web. There are no maritime pines in Bryce or DAZ studio and the only ones available on the web are very expensive.

Here is the state of my development; remains to round the tree and foliage and trunk and to apply the textures(foliage and bark)

So I need to select first the foliage part and modify it and then do the same for the trunk, but I don’t know to do the partial selections and I did not find in Bryce manual a topic on this matter.

Ah, okay.  Are your leaves and trunk separated meshes ?  THat looks very much to me as though you have made that from a terrain or a Symlat.  If so, then you would need separtae one for the 2 different parts of the tree.

If it is two separate parts then use shift+Ctrl and then select one part of the tree that way, while in the wire frame view

No unfortunately the the mesh is as a whole. I used Bryce to do this after making a mask with Photoshop elements 11 (I used this tutorial Bryce Tutorial: Create a 3D Gate Using a Black and White Picture

It looks to me that I’ll have to reform my mask by separating the trunk from the foliage in Photoshop….and create two objects that I’ll regroup once the textures are applied.!?

Yes, Is the only way to do it really

If your tree is exactly the same shape as the image you used to make it from you could try add the texture as a picture image in the mat editor, but it is not guaranteed to succeed.

I have a new problem I don’t see how I should solve it.

The trunk of my tree resulting from the image I used is not cylindrical. (see picture). how can I change that? The top branch should also
look cylindrical .

The technique is going to give you only a “cardboard cutout” - to be honest, I think your best bet would be to apply your image to a plane and use the mask you created to cut it out, to give a flat (but coloured) billboard.

The rendering would be horrible when the camera will go along the alley separating the palestra from the amphitheater see picture here:

I would suggest abandoning the method that you are attempting and find a tree shape in the tree lab which is close to what you are looking for and modifying it to what you want using all the available tools of the tree lab. Using a terrain type mesh is not going to produce a very good looking tree.

Have you experimented with some of the alternative trees
