Hi,
I created a texture and set to a camera. Another camera was set to a text.
Text and the texture are in different views. Always the text goes behind the
texture. What needs to be done to make the text appear always in front? I
tried by setting the texture state's rendering hint as T

I'm moving my backend to OSG, but I'm too chicken to do it all at

The transfer code should:

You can also use part of the nodemask You only need the top bit for the
culling, you can use the rest for any id number you want.
The advantage of this is also that the nodemask is saved in the osg file
without you having to make any modifications - assuming your id is valid across

The OBJ and 3DS plugins have duplicate symbol names, notably
