hello .... i can set DR on every model but except my model BC-305 .... ( with this model i have video and 3D wiev) but i can not set DR
I have had this problem too, I think GC knows about it and is trying to fix it. A work-a-round until they do is to edit your file and highlight the video link and right click it. Then select cut and press the save button. when you are back at your model the video will be gone and you can change the default render. then go back in and edit your part and re paste the link of your video back in.
Hope this helps.
