Hey this software is fantastic, im really looking foreword to the full version.
I did however manage to find a glitch I haven't seen mentioned here. The cycle change for a new model i made seemed to be working fine, it used a static png as the closed mouth and a talk cycle gif as the open mouth. I set the gif to be pretty slow so most of the time it just showed the first frame before the audio level went back down and it closed again. But when it did go to the second frame, i was reduced to a little talking mouth and there was some obvious glitching.
Luckily I checked my gif first and I found that on that second frame I had a little section of transparency that wasn't in any of the other frames. This didnt effect the gif when displayed normally, it was just a small patch in the chest area I didn't cover, but it did effect the way veadotube displayed it. Once I fixed the model, it worked perfectly, so no need to look into it too hard, but it would be good to mention it here with the solution. And once again, amazing work, i'm excited to see the full version.
