I spent quite a bit of time thinking of what to make the this challange. I chose the subject to allow the most amount of people the opprotunity to have some fun. I also wanted to spark some imagination. Now someone who only has bryce and no other application including no paint or photo program has to stretch the imagination muscles. Still there are a ton of objects out there that can be imported. You just have to use some imagination to create an image that fits the theme. No one just renders in bryce. No one. You compose, light texture, adjust your image in dozens of different ways at the very minimum. You actually spend more time doing this that making the initial object were you to model it within bryce. Choosing challange topics that only limit what can be created only in bryce and using no other application, that would include no post processing, no object imports and no custom maps or painted textures or material presets. Because those would require a external paint or photo application. You would very quickly run out of Challange topics and the whole challange topic would die real quick. A really alented Bryce artist would have no problem comeing up with something to fit the theme without haveing to resort to outside applications. But this challange is not just limited to really talented bryce only artists nor are they excluded. So as no one cam only render in bryce, The use of imported objects is not detracting from the faithfullness of the challange.
