    Hello.

    I have created a material plugin and whenever i assign that material to an object the initGLImage runs to calcualte the bitmap that will be used in the viewport.
     
    I want different image based on each object.
    Can i do that somehow ?

    As i see, even though i assign the same material in multiple objects, initGLImage runs only once.

    Thank you.

    I think it is doable.

    in simplematerial example, check for MATPREVIEW_MODIFY_CACHE_SCENE
    depending on the scene, you can set a member with the required data.
    make sure to copy that member "CopyTo function"

    using that member, you can change the initGLImage behavior.

    Hello,

    don't confuse the material preview image of the material editor with the OpenGL preview image. The OpenGL preview image is used to create a preview of a complex material in the interactive viewport. This bitmap is stored with the material and is only created for the material, not for each material/object combination.

    Best wishes,
    Sebastian
