I didn't really know where to post this, so I posted here, sorry if it's the wrong place.
Anyway, I'd like to know how is it possible to make a character visible to the camera if there's a block between the camera and the character, blocking the view. Kinda like in Mario Galaxy or Left 4 Dead, where you can see where your characters are even though there are walls blocking the view. I hope you understand what I mean. Thanks in advance

I think it's possible with a FFP effect in the entitie's material effect. But I don't how it goes.

perhaps create a 2nd View-Entity?
but i think, that would not look nice -.-

hmm...
Is there no way to change a shader for Outlines, to show the Outlines over everything ( like in diablo.. the red enemy marker behind walls )..

The

my.ZNEAR = ON;
set(my,ZNEAR);

commands might be able to pull this off

taken directly from the manual

"If this flag is set, the MaxZ value of the D3D viewport is temporarily reduced by the d3d_near_models or d3d_near_sprites factor, depending on the type of the entity. Adjust the factors for fine-tuning the clipping".

dont quote me on this working as you hoped. but i remember accidently setting this flag on the wrong model and i could see it through the walls
