Hi John,
I don't know of a reason why the .ive format should be size limited,
everything is allocated dynamically on demand by the plugin. I
haven't seen reports from the community w.r.t size issues with ive
either, your experience is the first I've seen pop up.

Hi Mahendra,
This look like you haven't taken into account the glare rendering in your
shader.
If you want the glare pass to ignore your model you need to set the value in
the glare buffer to zero

Hi Bawenang,
You should need to use osg::CullSettings::DO_NOT_COMPUTE_NEAR_FAR.
I'm not familiar with Delta3D but last time I heard about the osgOcean actor
that was generated for it, it was using osgOcean 1.0. The version in the
trunk now contains quite a few changes.

hi, Sergey,
Thank you for your help. I used Texture2D, not use mipmap.
I need to render the camera frame to the whole size of viewer.
Do you think it will improve my program's efficiency to use mipmap?

Hi,
could you explain what the texgen is for?
You could also try osg::TexEnv::DECAL instead of BLEND. This should make
the bottom texture appear in all transparent regions. You might have to
set a border with 0 alpha for the mask texture depending on the tex
coordinates generated.

There are bug on some ATI drivers versions that mess texture coodrinates when

.ive is deprecated. The new formats are .osgt, .osgb and .osgx.
These youe the serializer function, whhich should make it possible to parse it

Camera frame texture is likely to be not power of two size. Osg by default
resize textures to be power of two size, this can take a lot of time each frame
in your case. You can disable resizing by calling

Hi,
if you don't set texenv for texture unit 0, the osg default is MODULATE
which will then modify the underlying geometry's colour. Do you set a
colour for the geometry? If not, set it to white. Otherwise change the
texture unit 0 to DECAL too.

Hi Tang,
just some tips:
* disable the autoresizing of NPOT-images via
texture-setResizeNonPowerOfTwoHint(false);
* set the internal format of the image to GL_RGBA and the format of the
image to GL_BGRA, so the conversion is done by hardware/driver.
image-setInternalTextureFormat(GL_RGBA);
problem solved

Hi Eric,
The functions are virtual, so it is up to each loader to override it and
