Thanks for using Dropbox. Please do not use the Link-code-setup, I had asked IT to shut it off, as everyone needs to see what link is clicked. Anything else is not secure for anyone to use. I have changed it, in case you wonder.

What is going on in the scene is not in the images. Before you share more images, please don't. What I need is a project file. So I can see the material setup, the light, the camera settings, etc.

If the scene itself can't be shared, I'm sure it should be simple to place a few cubes into the scene instead and share it if it produces the same problems. I'm happy to explore it.

Thanks for the dropbox use.

If you can do that for various reasons, as this is a semi-public forum, please check with tech support.

Either way, I hope it is solved quickly for you.

All the best
