As VRay becomes more complex (or more simple some may argue) I find that the tooltips that appear when you hover your mouse cursor over a value disappear before I get past the first few words. Is there a simple setting to change to keep the tooltip there for longer?
I would love to see this as well!
I think 3ds max had some limit on how long tooltips stay on screen, so I don’t think we can do anything about it.
OK - it’s probably a bit of a waste of time having tooltips in that case as many of them are quite long. Maybe a little question mark next to each value that will take you to the appropriate web page for help?
I agree, it would be nice if they would stay up longer. They’re kind of unusable as is. Tooltips on custom toolbar buttons stay visible indefinitely on mouseover
This has been asked for so many times - come on Vlado, pahlease ! 
Will get to it…
Best regards,
Vlado
