Hi,

in dont know why, but in my case transparent gui elements (childrens) lead to also transparent parents(at the position of the childrens).
Is there a inverse "InheritsAlpha"-version? I want to see the parent by using transparent childrens. But in my case i can see through all windows.

Is this effect is desired ?
- sorry for my english

Doesn't sound desired. Can you reproduce it in the Sample Browser with a minimal example?

It seems to me to be an irrlicht renderer issue. So the problem just appears by rendering an 3D texture object with the irrlicht renderer in the gui background.

I can't help fix the CEGUI Irrlicht Renderer and we have no one currently among us active devs supporting Irrlicht.

If you find a fix please make a PR or at least post it here, to support the Irrlicht community.

This is probably a relatively easy fix, if it is related to CEGUI's Irrlicht renderer and not Irrlicht itself, because the CEGUI renderer is fairly simple regarding shaders etc.
