I am experiencing problems with renderings.  See the below image showing some red reflections which appear within reflective materials.  these red spots occur throughout various sun angles and from various view angles.  I am unaware of objects within the file which would create these red reflection.  any ideas?

I had similiar artifacts a little time ago. But they were disappeared after reopening and i couldn´t reproduce this bug. Ferry knows about.

I´ll attach a pic when i´m back in the office on monday.

And nice rendering that you created, btw.

They are render artifacts that only exist because of some numbers the 3d card uses incorrectly. We don't know how to reproduce it but probably updating your driver might fix it.

Nice scene indeed! However, I noticed that the floor and wall textures look rather blurry. If they look different from your original scene, it's most likely because Lumion automatically reduces the texture resolution while importing if you have a lot if high-resolution textures in your scene.

Small tip:

If you have a graphics card with a lot of memory and you want to increase the amount of texture memory that Lumion allocates to a model when importing, try holding down CTRL when you click the Reload button (The green circular arrow in the Material section) Wink
