urgent problem

[reality3d]

Hi all,

seem to be having a problem, when I render the image at 640 by 480 it is fine, but when I do it larger at any thing over 1500 by what ever it gets all these overbright warnings.
Any Ideas?

I think I have figured it out. was using RPC stuff and had deleted it as it causes overbrights, however for some reason, even though it is deleted the material is still associated with the scene.
