The textures should be cached in a similar way to the shaders. If they
are not in your case, it's a bug. Please file a test case.
Cheers,

I just put a QHash table to return the previous

Need I fill a bug for this?

I took a look with nsight and it appears that my textures are
currently loaded many times, certainly one for each object instance.
Need I manage textures resources my self?

I forgot to precise that mipmaps are already generated in our
file format and texture compressed (PVRTC, DXTC,...)

Hi,
I finally come back into Qt3D tests.
For the texture loader, I made my
own QAbstractTextureImage and QTextureDataFunctor, I do
the loading of our files in the override
of QTexImageDataPtr operator ()().
But I don't understand how to give to Qt3D texture's
format, mipmaps,... because I can set only buffer,
pixelType and pixelFormat on QTexImageData class.
Need I also implement my own
QAbstractTextureProvider functor to provide other properties?

Hi,
sorry, forgot to reply to the texture part.

Hi,
Is there a way to add a loader for our custom texture
format?
I think you can use the functor approach exposed by
QAbstractTextureProvider or QAbstractTextureImage.
Cheers,

We also have to use our existing shaders for
materials, but I don't know how to manage uniforms.
We are generating our shaders based on macros
depending of the number and types of light
sources,..., is it possible to keep that?
