Bert,

Performer uses 16 Bit texels as the default internal format, if not told otherwise. So depending on your modeling
software and the appropriate format loader you have to explicitly tell the modeler to use 24/32 Bit textures, or modify
the loader you are using which probably is not that good an idea .

For more info take a look at the man page of pfTexture::setFormat().

Hi Performers,

I've a question about displaying and rendering true color (24Bit)
pictures.
After modelling and texturing our geometrie, we use
perfly (pf2.1) for testing.
The resolution is 1280x1024_76 on a Octane MXI (maximum impact graphics).
Now the problem, all the textures (24Bit) looks like
true color pictures in a reduced color space...
They are smeared, not sharp, smooth colors look like steps...
But when we view them with e.g. xv or our modelling soft
they look ok !!!!
Is it a perfly or pedrformer setting problem ??????

Thanks for your help.........
