hi,

so my problem about the Shark tutorial is that i can't actually control the transparency of my image planes once i've mapped them with pictures with alfa-channel, just as was done in the tutorial. both diffuse and transparency buttons get locked, even though i load the picture into the diffuse slot only... the issue is only with the alfa-channel pictures...regular (rgb channel) pictures don't cause this problem (i can easily change transparency value)... it's not such a big issue for me but i'd be nice to be able to control planes' transparency with the locator via 'set driven key' option. so if anyone knows whats the problem please let me know. thanks.
