    Hi there,
    I' currently searchin for a possibility to browse through a material, for the plugin i'm developing.
    Now i want to check if a shader is a layershader or fusionshader, and browse through its subshaders.

    Am i on the right way if i do a GetData() on the Shader?
    If yes, how can know if its a layershader or any other?
    and how can i access its subshaders?

    Many questions for the first post, huh ;-)

    thanks for each reply,

    affa

    huh, thats really hard to figure out. That's how far i've come:

    m_shad->GetDescription(desc,0);
    BaseContainer *bc = desc->GetParameterI(DESCID_ROOT,NULL);

    but then, how do i get the infos? there is this IDS_SLA_LAYER, ...?
    Or are there any documents that could help me?

    thanks,

    affa

    Within an XSLAFusion shader you will be able to get the sub-shaders through the SHADERLINKs in the res-file. Unfortunately for XSLALayer there's just a single big SLA_BLEND, which is a private structure. So fusion yes, layer no, afaict.
    Getting the fusion sub-shaders should be a simple material->GetChannel(CHANNEL_COLOR)->GetShader()->GetParameter(SLA_FUSION_BLEND_CHANNEL, link, 0) operation.

    thanks very much for your answer.
    So there is no way to get Infos out of the Layer-Shader? That would be bad :-/
    Thats nearly the whole purpose of my plugin, d'oh

    Have you tried getting the layer shader and then browse through it with layershader->GetDown(); and then GetNext()? Not sure if this works, but worth a try. :)

    You're right, that will work to get the actual sub-shaders. However, I double checked with the develoepers and there's no way to access the actual SLA_BLEND structure. So you won't be able to access the blend parameters for the layers etc.

    hmm, ok thanks. the blend parameters whould also have been nice, but subshaders is a good start ;)
    I'll post the plugin here when i finished it

    Old thread revive - I take it that it is still not possible to access the layer shader properly?

    Huh!  Well i`ll be damned..

    Weird how they`ve included LayerShader in the docs and no mention of Fusion for example ( at least from what i can see ) even though fusion is accessible..

    Cheers Niklas.

    The word "properly" can mean different things to different people.
    AFAIK. We still cannot insert or remove shaders from the Layer Shader. And I don't think Maxon intends on fixing that in any future releases.

    Therefore.
    It's my own personal opinion that we do not have "proper" access to it. And never will.
