I experienced boygroupping problems with textured FX .
With any other patch without textured FX all is working fine in boygroup.
On the server all is ok and on the client too but the texture is not displayed
In the TTy client window all is ok texture is loaded and VVVV start with the good texture path.
the texture are on each computer , or only on the server ?
If only on the server , you have to place the texture on each client or use dynamic texture.
hope thats help you…
