Simpler method of refresh/texturing.

[Dannington]

Hi - it seems that the node which refreshes the texture from the spout stream is doing quite a lot - is it creating a material instance every time?

I'm actually using it to just get a texture which i'm feeding into a material which i've previously made, so to do that I need to call 'Spout Receiver' followed by 'Spout Info From' to get the 'Sender Struct Texture Color' which I need to apply to my material using 'Set Texture Parameter Value' each frame.

Would it be easier to initially get the texture reference, apply it to the material, then just use some kind of 'Refresh Spout' node each tick. BLUI runs like this. The same would apply to the pre-made material - you shouldn't need to make a whole material for each frame, just update the referenced texture.

What do you think?

Thanks for the plugin!

the material instance is created when check this and call the ResetTexture function:

if (!SenderStruct->MaterialInstanceColor || SenderStruct->TextureColor == nullptr ||SenderStruct->MaterialInstanceColor == nullptr){

        //TextureColor = new
        UE_LOG(SpoutLog, Warning, TEXT("No material intance, creating...//////"));
        // Prepara Textura, Set the texture update region
        Width = SenderStruct->w;
        Height = SenderStruct->h;
        SenderStruct->UpdateRegions = new FUpdateTextureRegion2D(0, 0, 0, 0, Width, Height);
        ResetTexture(SenderStruct->TextureColor, SenderStruct->MaterialInstanceColor, SenderStruct);
}

let me think about that
