Thanks for the responses concerning texture with the Impact!
One thing that I did notice is that the texture images being loaded in
were 774 x 1024 images, so we scaled them down as Ran had mentioned (to
75% of orignal) and they were loaded in and displayed ok on the Impact,
however, as expected, the resolution appears to degrad more
significantly as you zoom into the terrain than the previous 1024 x
1024 images did.
I am wondering if this image size is a limitation of the Impact in
general, or our particular Impact configuration? Should more texture
memory take care of this? Is our TRAM card providing additional texture
memory, above the standard 1 Meg? Can I expect the same situation with
the Maximum Impact, or should the two texture engines solve it?
I know that I may have diverged alittle from Performer, but any info
would be appreciated.
Thanks,
Bruce McQueary
