Analog-X64 does have a valid point on the percentage of import content vs. Bryce content,which is what I was trying to express in the guidelines for the new challenge.I don't feel we should ban imports all together,be they models,textures,effects etc.I think we just need to set a guideline for the amount used in a Bryce scene in order to say it is a Bryce image,or just accept Bryce as the render engine used and judge the image on it's artistic merits only.This is going to be a tough call,but I would comply to whatever rules are stated.
