It sounds like texture_data is null. It's added automatically by the runtime if the plugin specifies the texture flag. Are you using animations instead? That uses a different system. Animations aren't actually supported in the C3 SDK right now, so if you are somehow using that already, please file a bug about it to make sure the implementation is completed.
Hi, thanks for your quick reply lucid and Ashley
Just to clarify a bit, I followed the instructions on page 1 of this thread to the letter, using the "spritesheet" (I just import the spritesheet in the Spriter animation window under the "Animation 1" name, I don't change it) and import the "scon" file method and the C2 runtime in advanced section of C3. If I try to select the C3 runtime, it does say that the addon is not supported yet.
Another thing I noticed is that if all of the spritesheets I import are all pretty much the same size, I got it to work! But if one of them is way bigger, then the bug appears and all of the other Spriter objects use that big spritesheet instead of their own.
Please let me know if you'd like me to try anything at my end or log it as a bug.
Thanks a lot!
