I want to make multiple float buffers (RGBA32F) to use for the MRT.
OpenGL ES 3.0 supports float texture, but it seems not to support float renderbuffer for the MRT.
There is no way to use float texture for the MRT buffer?

This comes as a surprise to me too, as I could bet the specs were saying RGBA32F was only color renderable (but not filterable so only render buffers would work, not texture attachments) only a few days ago, but I think they recently changed it. You should try using RGBA16F though, that works, I have an issue where RGB16F doesn't work for some reason on Adreno 320.
