Sorry I have not been back before now but three days a week I'm under medical care.
You will find attached the image of the problem I described. The test was run using stock FPSC Scifi segment's Full Labatory in a 3x3 room with Blinking Corridor as a 3 segment hall. I used Control room auto door for the connection.
As you can see the whiteout happens even without shader effects turned on. For this image it is default FPSC install with v1.17 upadte, so Bloom is active as stated in the addenduim. I will test the bloom effect later today by turning it off. The lighting is set to Full for all the test images.
I will be upgrading my PC soon so this issuse my just go away. My current PC is old and stock with a wippy vid card. FPSC X9 v1.16 runs like a charm on this PC, so i'm able to design using that for now. If I could get the full effects before I upgrade that would be great.
Thanks again for all the help.
