What are you trying to achieve exactly?

[fanbinnet]

I plan to load three gltf at the same position, the color of the overlap will be too bright.
I need to lower the color of the over-bright parts and keep the color of the rest of the parts the same.

Sample-gltf-bloom is very helpful for my question.But it don't contains in latest code.
I find it in old version code,and it hlep me resolved my problem.

Glad it helped. Note that we replaced that sample with a simpler one (see samples/rendertarget.cpp) after we introduced our first-class bloom effect and post-processing framework.
