Proper RGBA32F fbo support in deferred rendering

[HezkoreParticipant]

I notice that despite the Mojo3D deferred renderer requesting an rgba32f texture, Mojo actually only provides 8bit rgba textures.
This means dark colours are losing precision, due to the gamma adjustments (for linear lighting)

Here’s a simple gradient:

And here’s how it looks in the deferred renderer:

See how poopy it is?
And that’s without any light sources and the EnvTexture being a 1×1 black texture.

Is there an eta. on when we can expect rgba32f support so that linearspace lighting doesn’t ruin the darks?

Here’s the code if anyone wants to give it a go themselves.
The “test.png” file is in the first post.

See the fix here:

Mojo3D PBR material "glows in the dark"

[HezkoreParticipant]

Thanks.
Why is PixelFormat.RGBA32F not default.. infact you’ve commented that out.
Is it for backwards compatibility or something?

UPDATE: Looks like it’s been changed in newer Mojo3D, it was just my old version

[Mark SiblyKeymaster]

Not sure what the default will be yet. Float textures are strictly speaking an extension under GLES2.0 so I initially just wanted to play it safe.
