I have a .x file and the material is 0.690196 this represents a light blue color or 0xAFD6F6
I am having trouble getting from 0.690196 to 0xAFD6F6
When i multiply it by 1000000 and use hex to display the value i get 0x0A8814
Ultimately i want to set a sprites color using it

Attached is the .x file

The value 0.690196 is the first component of the color of the material you are looking for
It's the Red component followed by Blue,Green and Alpha...combined it is Lightblue Indeed

You want:

Also there are more who need Vertex Colors
Vertex Color
Load Object with Color

...And they ^ are the active part of our community
I'm sure there are much more in the silence/much bigger part.
I was one of them a long time ...before I started writing shaders.
I see every feature request as some sort of % ...sadly I don't know how many active/passive members TGC have or how many AppGameKit versions are sold
Maybe TGC/Paul should look into Vertex Colors if he finds some time

Maybe usefull sidenote:
In the documentary of Library AppGameKit uses to load the objects: Assimp
Quote: "if parts of the model use a different material, this part is moved to a separate mesh at the same node"

But it seems only the x format behaves like that

Attached is my progress with the kenny models.
Run the app and you will see the models loaded in agk with their colors
click right side of the screen for the next model, left side for the previous model
there a still quite a few models where the normals are haywire (i'll look a little further into that)

Well done
I tried to read the material color from the file, but instead of creating images from it I made a vertex color shader and didn't get the linkage between Vertex and Face working.
I also attached images to the mesh at some point but not like you.

Thank you
There is nothing left to stop me from creating an awesome 3D-top-down-multilayer-zombie-shooter

ps the "delim" parameter of the "GetAToken" function is somewhat redundant
