I am studying the same features of water. I am interested in nands work with sculpties too. its how i came to your web page. The approach using moving textures is ok.. if it can be smoother and flow better. I use psp / animation shop to create 2d flowing water effects. rippling water has often an underlying cycle, the ripple in a stream is often near stationary and the surface is what one see`s flowing over that. Im thinking of combining ( if possible ) two elemental 2d movement anims on a rippleform sculptie. element 1: the standard revolving prim texture.. ie how one gets waves on a shore by revolving a texture on a prim. element 2: the animation of that texture... say 16 frames thats how many frames i use to create flowing water falls.. haze.. water movement, smoke flames etc..in 2d using psp and animation shop. so the water surface moves and its cycle changes on a rippled prim.. ive not tried combining the two anims.. element 1 example is: llSetTextureAnim(ANIM_ON | SMOOTH | LOOP,ALL_SIDES,0,0,0,0, 0,0.20); element 2 example is: llSetTextureAnim( ANIM_ON | LOOP , ALL_SIDES, 4, 4, 0, 16, 15); ive no idea if its possible yet.. do you think so? on a rippled prim the right shape, waves, water and smoke and fire would be much more defined naturally. just thought i would bounce that off you..:) regards Incony The Tree Of Life Trueblood 51, 78, 24
