   Seems A.RABBITS code works, and workds quite well... But, with a few caveats: - The effect is broken when the material is applied to a mesh used in foliage mode. The same mesh/material works perfectly as a billboard as a static mesh, but rotates through the air (rather that simply angling its face towards the camera) when…

   Hey all, Okay! So this may be a little confusing but I need to understand how to "code" something in UDK. I need to have my grass alphas always face the player as he is walking around them. So, in L4D2 when you are walking around grass cards they always face you so you don't see the weird disappearing faces or the side of…

   Nope, that doesn't work... Does the A.RABBITS code work as described, or is it as broken as it looks in tomacmuni's video? Cheers.

(yeah ,1 more axis is enough but knowing the other 2 would be great)float4 output;float3 CameraToObjVector;//Get Camera to Object…

   test postx sorry this is playing up at work, already wrote a response that got lost. Basically you can do this three ways. In decreasing complexity. 1) i think you'd need to transform the matrix for the vertex shader to get it to stick to screen. you cant do transforms through the built in nodes in to vertex shader (at…

   you can make a shader that makes a fake sprite by using world position offset. http://udn.epicgames.com/Three/WorldPositionOffset.html You need to make a material that rotates the vertexes of the model to face the player. It's a bit complicated for me to easily make an example so hopefully this will give you an idea and…
