losing sight of object when adjusting sunlight level

[arisdemos]

I am setting up my lighting on tgd that has some seven or eight objects and populations as well as a procedural landscape, and as I fine tuned the lighting upward to a brighter shade all of a sudden one of my objects moves out of sight as if it dropped down in elevation below the ground. When I move the object back upward then the lighting changes back to a darker tone. Can anyone explain why this should be occurring?

The object you're seeing moving is probably the sun itself! It does have a visible bounding box...

No one of my actual objects sinks below the ground when setting the intensity of the sunlight lower then if I set the object back upward the light/sun goes darker.

can you upload some screenshot comparisons or a zip of the files involved?

I agree, what you're describing really doesn't make sense and I can't reproduce here, so having a scene file to test with would really help. Ideally you could include all the objects, though I realize that may be difficult.

This tgd has a very large number of objects and populations I put the basic tgd minus all additional figures up some time ago. the upload was a volker tgd that I altered with a painted shader mask to expose an underlying dirt and rock layer. The individual object that moved out of sight was xfrog's pink prickly pear cactus, and the rest of the objects where either xfrog or xfrog objects of my own creation. There was one saguarro cactus not of xfrog creation that I was adjusting the light to bring out texture features when this aberation occurred. I will be uploading the image in the WIP section for Frank;s contest within the next couple of days and I can put up the final tgd sans objects then. Thanks for the input so far, and I do believe this little mystery burial of my object warrants me/someone trying to get a repeat occurrance going if possible.
