Hi Im trying to export a TreeIt tree into AGKStudio.
The main 3D tree object imports fine and the textures do. But one texture covers the whole tree?
I usually make a 3d object and then make 1 texture for the whole object. TreeIt and some other programs have several textures like one for bark and one for leaves for example.
Is there a way of importing an object with these different textures into AGKstudio?
Or is there an easier way or different program?
Thanks
Chris

If you use the .x file format to export then load into AppGameKit it creates an object with multiple meshes if more than one texture is needed. (typically 2 meshes)

You can then use GetObjectTexturename() to get the names of the texture filenames that you need to apply or set them in your code directly.

You then use SetObjectMeshImage() to set the correct image to each of the meshes in the model




You should also, generate mip maps, and turn on alpha masking and set the cullmode to 0 too to get it to look near correct. Ohhh and also set texture wrapping to on as well. To make it look really really good you will need a decent shader with translucent rear face shading

You could use the texture atlas tool in TreeIt to create a single texture instead and so you wont have to load multiple textures instead.

Don't know if Chrissell had any luck with this one but I am struggling with the same problem.
I have tried to follow your suggestions Bengismo but still only get 1 texture to apply.

Anyone have an example code?

Thanks

if the leaves are children objects you can do it like this


Well maybe without the randomness I use lol but that code works well for trees I have converted

@ fubarpk. Thanks for your coding example but unfortunately all the tree examples that I have do not have the leaves as children. Useful though for other projects.

Hopefully i will find a way.

Hi

My GodRay Demo in the Shader Pack uses a Tree from Evolved's TreeIT too.
I had it setup like so:

@ Hi janbo and thanks for your posting.
I have your Shader Pack which certainly enhances the model, however the bark and leaf textures shown in your post have been merged in to 1 x png presumably through TreeIt.
With textures merged you are still only applying 1 texture image to an object whereas I really need to know if it is possible to add 2 or more textures, i.e 1 for trunk bark and 1 or more for leaves.
Unfortunately I have been unable to get TreeIt to run on a W10 64bit pc as it was really only intended for the 32bit DBPro days.
Consequently I am unable to merge textures unless you or anyone else know of another app that can do this or APKS already has the capability for this but which isn't very obvious.

Cheers

As per my post above...Use GetObjectNumMeshes() to find out how many meshes there are in your object. Its quite likely to be 2. You then use SetObjectMeshImage() on each mesh to set its image. So one mesh has bark applied and one has leaves.

Hi Bengismo.
I did try your method earlier but the first 4 models only had 1 mesh each so didn't work so I gave up.
I have now found 1 model with 3 meshes, so fingers crossed.

rem *** Loads the Object in direct x format ***
obj_Palm_x = LoadObject( "Palm.x" )

rem *** Use this to get the texture name for each image ***
TexImage$=GetObjectTextureName(obj_Palm_x,2) : rem *** Texture index 1 to 2

rem *** Position Object to fill screen ***
SetObjectposition(obj_Palm_x,0,-10,0)

rem *** scale object ***
SetObjectScale(obj_Palm_x,.2,.2,.2)

rem *** load images found from GetObjectTextureName ***
img_palm02 = LoadImage( "palm02.png" )
img_date_palm_leaf = LoadImage( "date palm leaf.png" )

rem *** set images to mesh ***
SetObjectMeshImage(obj_Palm_x,1,img_palm02,0)
SetObjectMeshImage(obj_Palm_x,2,img_date_palm_leaf,1)

rem *** darken scene a bit ***
SetAmbientColor(50,50,50)

rem *** turn on apha masking ***
SetObjectAlphaMask( obj_Palm_x,1 )
rem *** Cullmode to 0 ***
SetObjectCullMode( obj_Palm_x, 0 )

do
Print(TexImage$)
Sync()
