Hello Ryan, I have done this with Xpression for some TV-Shows. I doubt, that this would be possible just within Xpression. I used the Xpression SDK within a .net framework programming. The issue is, that you need access to a volume analyser. There are some libraries available to do this in .net. ...

Hi Sonja, a second approach you could do is putting the content of scene2 as a group into scene1. In this case you could do it in visual logic by setting this group invisible if the conditions do not met. There is imho no way to adress a different scene from within visual logic. Tom ...

Try to add 2 shaders to your material. 1. Refraction with which you can make a material transparent with refraction effects like glass or diamond. 2. A bump map shader.

Hi Avery, the answers to your issue are already given. Anyhow there might be circumstances where there is no way to avoid to use the OnRender event. As Garner said whenever you can avoid it you should do it. Situations where you cann not avoid to use On_Render might appear, if you need information ...

Hello guys, is there any way to find out by code, if a specific scene in Xpression contains a script or some visual logic. I would like to use this information to automatically build a projects documentary which would be helpful if you pass a project to other colleagues. I did not find ...
