Hi! I'm trying to cull 3D object during runtime, it is esential for one of my
game scenes.
I can not think a way to do it using vertex animation. I can not "hide"
vertexes, as far as I know.
The only way I can think is to cull object at runtime somehow? I can not simply
cut its mesh, because it will need to return to normal later. And I think
creating mesh duplicate from object, cutting it somehow, will be too long.
Maybe some shader? Like, is it possible for shader to hide certain vertexes,
lets say, on the right side of objects X axis? Or anyone has some other
ideas of how to do it? Any help appreciated.

maybe you could use a alphamap for your texture and than shift the tex

What do you mean by "culling" the object. Culling means removing hidden and hence invisible surfaces of an object to me. This is automatically done by the engine. You don't need to that yourself.

Sorry, I used word "culling" to make it sound simplier. So You know what I was thinking ^_^ Just cutting the object

Thanks, Revo, I'll look into alpha maps, maybe this will, indeed, be a solution

Some time ago there was a "dissolving shader" written by some user. Maybe you could do a search on the user contrubutions forum or the shader forum for this. If I remember right this one could do what you want to achieve.

Thanks a lot for the tip! Currently, I can not find it neither using a7oogle or forum searches, probably it was there by different name? But I'll try some other search quires and see how far I can get.

I spent some time seraching but I can't find it eather. Maybe someone else remembers?

Hmmm... Probably I'll create topic in shaders forum. Looks like I'll have to write it myself.
