Problem solved! Thank you!

Hi all,

I want to use a "config" plugins to read the loading queue in R19. A QueryStartupOrder() function works well in R20 and R21, but it seems like that it is not supported in R19. So, is there a way around it? Thanks!

Thank you for your reply, the BaseShader::Sample() helps me solve this problem. (Except that when the layer shader use transform layer, scale transformation is not automatically handled.) Anyway, thanks a lot!

Hi,

I'm working on r20, and I found I can't use BaseShader::BakeShaderIntoBaseBitmap() because it is a new feature in r21. Trying find a way around, I want to extract the bitmap of the layer shader. However, my code does not work.

BaseBitmap* diffuseBitmap ;
GeData gd;
BaseShader* shader = bm->GetChannel(CHANNEL_DIFFUSION)->GetShader();

if (shader->GetType() == Xlayer) {
    LayerShader* layerShader = static_cast<LayerShader*>(shader); 
    LayerShaderLayer* layerShaderLayer = layerShader->GetFirstLayer();
    while (layerShaderLayer != NULL)
    {
        if (layerShaderLayer->GetType() == LayerType::TypeShader)
	{
	    Bool res = layerShaderLayer->GetParameter(LAYER_S_PARAM_SHADER_LINK, gd);

	    // diffuseBitmap = layerShaderLayer->GetPreview(); // this does not work, too!

	    BaseLink *bl = gd.GetBaseLink(); // program stop here, and I can't see why
	    BaseShader *thisShader = static_cast<BaseShader*>(bl->GetLinkAtom(bd));

	    thisShader->InitRender(irs);
	    diffuseBitmap = thisShader->GetBitmap();
	    thisShader->FreeRender();

            break;
	}
	layerShaderLayer = layerShaderLayer->GetNext();
    }
}
else
{
    // ...
}

ShowBitmap(diffuseBitmap); // can't see anything here when using 'layerShaderLayer->GetPreview()'
diffuseBitmap->Save(fn, FILTER_JPG, nullptr, SAVEBIT::NONE); // fail when using 'GetPreview()'

Could anyone kindly explain where I am doing wrong? Thanks a lot!

Thanks a lot!

Hi all,

I'm trying to use BaseShader::BakeShaderIntoBaseBitmap() to get a 2D representation of the shader. However, I couldn't get the correct result.

BaseDocument* bd = GetActiveDocument();
InitRenderStruct irs{ bd };
BaseBitmap* bit = BaseBitmap::Alloc();
BaseShader* shader = mat->GetChannel(CHANNEL_DIFFUSION)->GetShader();
shader->BakeShaderIntoBaseBitmap(*bit, *bd, irs.thread, false, irs.document_colorprofile, irs.linear_workflow, true, 0, 1000, 0, 1000)
ShowBitmap(bit);

I have read 'BaseShader Manual', but I'm not sure where to get a parentThread, so I used irs.thread...

Any ideas or examples?
