Is there any way to access the opacity of a BodyPaint layer? I have tried reading the ID_PAINTLAYER_OPACITY value from the BaseContainer as well as GetParameter but it doesn't seem to work.For reference here is where the ID_PAINTLAYER_OPACITY is defined.

And although I haven't tried it yet, since opacity didn't work, I would also like to access ID_PAINTLAYER_BLEND as well.
Ideally I would like to be able to both read and write these values.
Cheers,

Hello,
at least in R18, setting ID_PAINTLAYER_OPACITY seems to work fine:
// get texture PaintTexture* texture = PaintTexture::GetSelectedTexture(); if (!texture) return false; // get layer PaintLayer* layer = texture->GetFirstLayer(); if (!layer) return false; // change opacity GeData data; layer->GetParameter(ID_PAINTLAYER_OPACITY, data, DESCFLAGS_GET_0); Float opacity = data.GetFloat(); opacity = opacity* 2.0; layer->SetParameter(ID_PAINTLAYER_OPACITY, opacity, DESCFLAGS_SET_0); // set blend mode layer->SetParameter(ID_PAINTLAYER_BLEND, LAYER_MULTIPLY, DESCFLAGS_SET_0); EventAdd();
best wishes,

I have only been testing with R17 so far. Great to know that its working in R18. My code was doing the exact same thing as what you have there. I will double check this all again, but its good to know that its working for you in R18.
Cheers.

Just a follow up on this. Totally my own fault. I was missing an EventAdd();
Silly mistake on my part. Thanks for testing.
